Fall River, MA — Motion Control Components Application – Toxic paint is used on the bottoms of large ships to prevent fouling, which is when a biofilm layer develops, decreasing the ship’s efficiency in moving through the water. The toxic paint continually leeches copper and other heavy metals into the underwater environment as well, causing damage to the organisms that live there. To further complicate the matter, the paint must be blasted off and replaced every 5 to 10 years, at which time literally tons of toxic waste is produced and needs to be disposed of. A ship that operates with a clean underwater surface free from fouling—even thin biofilm layers—will operate so much more efficiently that potential savings can easily reach over five percent in fuel costs alone. Without the concern for fouling, a ship’s underwater coating can be engineered for corrosion protection and longevity rather than its need to eliminate the potential for biofouling. If realized on all the ships operating in the world today the energy savings would greatly reduce the presence of greenhouse gases, as well.

To eliminate the requirement for toxic paint and its cleaning waste, there needed to be a method to “groom” the biofilm from the underwater portion of a ship. The idea was to create important changes for the ships being built as well as for the environment. That is where the HullBUG (Hull Bioinspired Underwater Grooming) concept originated. “The most important feature of the HullBUG is its small size,” according to SeaRobotics Research Engineer, Dr. Kenneth Holappa. “It is only about half a meter in length. This was a necessary design feature, needed to allow the vehicle to maneuver over the curved surface of the hull while continually maintaining close contact with the surface.

This close-up of the HullBUG clearly shows its sensor alignment
system that helps it keep on course while cleaning a hull.

Because there are hazards associated with operating such a device underwater and in a harbor environment occasionally a HullBUG might be lost or destroyed during operation. Keeping the size and cost of the system low definitely helped to eliminate damage as a major obstacle to implementation. So, from the very beginning of the project, small size and low cost have been identified as being critical to the satisfactory implementation of the HullBUG project. As can be expected, this need to maintain a particular size and weight filtered into the selection of every component of the design.

Motion Control Components

The selection of the motors to drive the HullBUG involved a number of critical engineering constraints and compromises. SeaRobotics decided to make two basic models, one with wheels and one with tracks, and offer several options for keeping track of the system’s progress, which will be discussed later. Sizing of the motors, for example, required a calculated estimate of the power, speed, and torque characteristics of the manufactured devices. Determining factors included the resistance caused from pushing the grooming tool across the surface of the ship, the hydrodynamic resistance of the vehicle itself as it moved through the water, friction losses in the shaft seals that were used to protect the motors from the saltwater, and track or wheel friction dependent on which version of the unit was used.

maxon motors offers a full line of fractional horsepower moving coil DC motors and brushless motors ranging in size from 6mm to 90mm, and from 30 mW to 500 watts. They also offer gearheads, controllers, and accessories. “The breadth of their product line and quality of their service helped us to feel comfortable that we had selected the right partner,” Ken said. Flat motors manufactured by maxon Precision Motor provide long life along with their low profile package. The entire EC series of brushless motors are electronically commutated, which enables them to have extremely long motor life since there are no mechanical brushes to wear out. The motors incorporate ball bearings or ruby bearings that also add to the longevity of the motors, especially needed in such harsh conditions. The flat motors were designed specifically for robotics applications where size and weight are important selection criteria. The EC45 flat motors selected for the HullBUG are very efficient and weigh only 75 grams. Continuous output power is 30 watts, while the maximum speed is 10,000 rpm (much faster than what was needed for this application). The important specification for this application was torque. Even under the potentially harsh environments that the HullBUG would be engaged in, the EC45 offered a maximum continuous torque up to 56.2 mNm depending on the winding chosen by the user. The Maxon brushless motors are built to IP54 standards, which was important to the application. Furthermore, the motors were also available in the system voltage that SeaRobotics required for the HullBUG application.

According to Ken, “The large load capacity of the shafts of the GP42 gearhead allowed the wheels to directly mount to the gearhead shaft, greatly reducing the complexity of the overall design of the system.” Gearheads manufactured by maxon are available in a wide range of ratios to enhance speed reduction and/or torque multiplication dependent on the needs of the user’s application. Concentric input and output helped to facilitate simpler and more direct mounting arrangements, as well.

Given that the HullBUG vehicle was to be completely autonomous, it had to be designed in such a way as to operate for many hours on batteries (cables would simply get in the way of the grooming operation). In order to maximize battery life, the grooming of the biofilm had to be performed in the most efficient manner possible. Navigating in a random pattern may eventually get the job done, for instance, but not in a reasonable amount of time. Plus, a typical ship presents a very large underwater surface, often as upwards of three thousand square meters. To keep this amount of area groomed it is expected that a user would employ multiple HullBUG vehicles to operate at the same time and, consequently, require a method of acquiring sophisticated coordinated navigation.

Navigating the HallBUG

A toolset of navigation modes has been created to allow multiple HullBUGs to efficiently groom a ship by dividing the ship’s underwater surface into regions. Numerous algorithms have been incorporated to accurately groom the ship in steps down to the turn of the bilge. Additional algorithms and associated sensors are used to allow efficient grooming of the flat bottom of the ship. Miniature acoustic ranging sonar (MARS) is also an option for navigation control of the HullBUG. This is where a very small close range, pencil beam sonar was specifically developed to allow the vehicle to “see” an upcoming wall or cliff condition such as bilge keels and bow thrusters. Yet another mode of navigation uses a MEMS rate sensor for navigation information. Another feedback mode uses encoder based odometry. Hall sensor feedback from the motor is used as an encoder signal to establish an accurate estimate of odometry. Hall sensors were used instead of optical encoders because of size and cost. The Hall sensors provide better than 1mm accuracy in the measurement of odometry with the motor/gearhead combination chosen.

Ongoing Software Development

An autonomous vehicle is often software heavy in terms of engineering efforts once you’ve selected and implemented the proper motion control system. Getting smooth reliable navigation maneuvers that result in accurate positioning in a widely varying environment was one of the more difficult challenges for the design team. Multiple layers of software were necessary for handling the number and variety of possible events that can occur during grooming. And, the proper organization of the control logic to allow extensibility of navigation behavior was the most difficult part of this complex system. “Software development will continue to be an ongoing effort even after the years already put into it,” Ken said. “Though the vehicle is completely operational, there remains a considerable amount of on-ship testing to be done.” As the project moves forward and into the field, there will no doubt be additional issues that will crop up and need to be addressed, as well. Even now, the vehicle must be able to reliably accomplish its task in a hostile environment and in an unmapped terrain. Then it has to be able to return to the waterline of the ship for retrieval.

This operation must be done repeatedly for days, months, and years, and with multiple systems in the water at the same time. Although this sounds as though it is overly difficult, according to Ken, “A technician was recently trained to use the vehicle and was fully competent within a short period of time. The user interface was borrowed from SeaRobotics’ Unmanned Surface Vehicle (USV) product line and presented an intuitive graphics-driven interface that has hundreds of hours of use by many different customers.” The vehicle is operational and the navigation software is working. The next primary focus will be the structuring of the interface to improve ease of use and allow non-engineering personnel to manage operations.

Is Your Workplace Safe? Make sure with the Free Gotcha Stick!

safety gotcha stick

 

STI — Omron introduces the safety Gotcha Stick Safe Distance Scale. This three-segment safe distance stick accurately tests the allowable barrier opening size based on the distance from the point of operation. It features English measurements on one side, and Metric measurements on the other.

Although not officially adopted by OSHA, the safety “Gotcha Stick” is based on data from “A Review of Machine-Guarding Recommendations,” by Donald R. Vaillancourt and Stover H. Snook of the Liberty Mutual Research Center for Health & Safety. This data redefines the dimensions of the human arm for the purposes of machine guarding. The resulting new stick has been modified to include openings of less than 1/4 inch over the first 1/2 inch distance.

Guarding machinery by means of hard (fixed) barriers is one of the main ways of protecting personnel from point-of-operation hazards. The safety “Gotcha Stick” is the easiest means of verifying that openings in hard guarding will not allow the point-of-operation to be accessed by the operator.

With headquarters in the heart of Silicon Valley, STI was founded nearly 30 years ago and employs more than 350 people. STI has been selected twice by Forbes and three times by Business Week as one of the “world’s best small companies.” STI’s safety products are used to protect workers around machinery, automated equipment and industrial robots. Their products serve a wide variety of applications and markets, including semiconductor, automotive, electronics manufacturing, packaging and consumer markets.

Motion Control Application – Implantable medication delivery systems: Where every microliter counts!

Motion Control Application – Implantable medication delivery systems can have a decisive influence on the quality of life of the patients. In many cases, such delivery systems are vital for the survival of the patients – the systems have to be absolutely reliable. maxon motor manufactures high-precision micro drives for medication delivery systems.

Maxon Logo

motion control application - implantable pump Fall River, MA — Motion Control Components Application – Patients that suffer from chronic pain, metabolic disorders, diseases of the central nervous system and tumor diseases require accurately dosed medication. Here implantable medication delivery systems are used. Through the localized medication delivery, the dosage can be reduced to the required minimum. These infusion systems thus improve the quality of life of the patients. For many patients, it is only the medication delivery system that allows them to have a life outside of the clinic. Repetitive invasive, painful operations can be avoided. The risk of medication dependency and undesired side effects are reduced to a minimum. All these factors can contribute to the disease no longer being the central focus of the patient’s life. For example, an active implant is implanted in the lower abdomen directly underneath the skin, where it delivers the medication dosage, programmed by the physician, to the body at the defined times of the day. The implantable unit has a wireless data interface to a patient interface by which the dosage can be adapted at any time. At regular intervals, the internal medication reservoir can be refilled by a specialist. The life span of the active implants measures many years and is limited only by the life of the battery. The core of the active implant is a piston pump manufactured by maxon medical, which specializes in medical technology and is a division of the maxon motor Group. However, the micro drives for implantable medication delivery systems are not comparable with customary maxon motors. In a customary motor, rotary motion is generated and yields torque and speed of rotation. maxon miniature piston pump The reciprocating piston pump generates a linear movement that results in liquid pumping. The individual parts of the pump have very narrow tolerances and allow the pump volume to be adjusted with a precision of less a microliter per piston stroke. As active implants are in direct contact with human tissue, biocompatible materials are an absolute requirement. Therefore, in most cases, titanium is used for the implants. Machining of titanium, especially safe and reliable laser welding, requires a very high level of expertise. Special testing and quality methods, such as inspecting the penetration depth, microhardness and density of the weld seams, are established procedures at maxon medical. The customer requirements on the product are thus fulfilled and the reliability and constant quality of the manufacturing processes are guaranteed. The entire assembly of the implantable micro drive takes place under cleanroom conditions. maxon medical – Specialist for medical drive solutions and active implants maxon medical specializes in the manufacturing of medical drive solutions for active implants. The division received ISO 13485 certification in December 2008. The quality management system and the project organization ensure safe, reliable and standard-compliant products and provide the customer with a sound basis for statutory approval of the final products. Professional project organization and a proven risk management system allow efficient implementation of customer projects. Strict maintenance of statutory requirements has top priority in the implementation of medical technology projects with risk class IIb + III.

Van Nuys, CA – — Motion Control – High Resolution, Motorized, Pan-Tilt Stages have been added to the extensive line of OES (Optimal Engineering Systems, Inc.) motion control products. These motorized Pan-Tilt Stages are available in two sizes. The PT60-1 Pan-Tilt Stage is a combination of two 60 mm (2.362 in.) rotary stages and the PT100-1 is a combination of two 100 mm (3.937 in.) rotary stages, set at a 90O angle to each other. The rotary stages of each Pan-Tilt stage features a high repeatability of 0.005O (18 arc-sec), a positional accuracy of 0.005O (18 arc-sec), and a resolution of 0.001O = 3.6” (10 Micro-steps per Step Motor Driver in use). These Pan (horizontal table)-Tilt (vertical table) Stages are deal for: Scanning, testing, inspection, assembly, positioning, laser and micro machining, pointing optics and cameras, and other applications.

The pan and tilt axes on both stages have precision V-grove and crossed roller travel guides and are driven by a worm gear with just of 0.005O (18 arc-sec) of backlash. These compact, easily integrated motion control Pan-Tilt stages weigh just 2.0 kg (4.4 lbs) for the PT60-1 and 4.4 kg (9.75 lbs) for the PT100-1 and load capacities are 10 kg (22 lbs) and 20 kg (44 lbs) respectively). Each axis is driven by a standard bi-directional stepper motor with a knob for manual adjustments and each rotary axis has a vernier scale for setup. The knob on each motor can be replaced with an optional encoder for position verification. Travel speed of each axis is 12O per second with a stepper motor or for higher speeds and closed loop operation, servo motors are available. Electrical connections are made using 9 pin DB-9 connectors. The PT60-1 and the PT100-1 Pan-Tilt Stages can be ordered as complete plug-and-play systems with a multi-axis controller, joystick, trackball or keypad.

Motion Control Servo2Go-Logo

Motion Control Components – Servo2Go.com announces the release of the DZRALTE Series of High Performance Digital Servo Drives from Advanced Motion Controls of Camarillo, CA, which are engineered to conquer the most demanding industrial applications!

The DZRALTE Series are motion control digital servo drives that control brushed & brushless servomotors in a compact form factor which make them ideal for embedded applications. These fully digital drives operate in torque, velocity, or position mode and employ Space Vector Modulation (SVM) which results in higher bus voltage utilization and reduced heat dissipation compared to traditional PWM drives. The command source can be generated internally or can be supplied externally. In addition to motor control, these drives feature dedicated and programmable digital and analog inputs and outputs to enhance interfacing with external controllers and devices.

The DZRALTE Series feature a RS-232 interface for drive configuration and setup as well as a RS-485 interface for drive networking. All drive and motor parameters are stored in non-volatile memory. Drive commissioning is accomplished using AMC’s powerful & user friendly free DriveWare software.

The combination of a DigiFlex® Performance™ DZRALTE servo drive with its DriveWare software establishes a new benchmark in versatility!

Motion Control Capabilities built into the DZRALTE servo drives include:

  • Size Ranges: 10-175 VDC @ 6A to 30A continuous (60A peak) Output
  • Full tuning control of all three servo loops: Position, Velocity and Torque!
  • Real-time oscilloscope with up to 8 channels to ensure that tuning achieves the highest performance
  • Status window with over 50 simultaneous channels for drive and system diagnostics
