POSITAL Kit Encoder for Servomotors and Robots 

Vaughan, Ontario, Canada — Motion Control Components — A very exciting development in the area of robotics is the development and growing popularity of so-called collaborative robots, or “cobots”. Cobots, in contrast to traditional industrial robots, are designed to interact with human workers in a shared workspace. They are typically smaller and less powerful than traditional factory robots and are equipped with a variety of proximity sensors, load sensors and other features designed to avoid dangerous collisions between the robots and the people working around them. This focus on safety means that cobots are easier to deploy in a normal factory setting, since they don’t required special fenced off operating areas. Cobots have been used to perform repetitive tasks in light assembly, packaging, materials handling and medical laboratories. Cobots have also been used to help workers avoid direct contact with environments not conducive to direct human interaction, such as high temperature environments, chemically aggressive reagents and toxic pathogens.

Enabling Technologies for the Cobot Revolution

Motion Control robot with POSITAL Sensors

Many cobots are designed to mimic a human arm, with flexible “shoulder”, “elbow” and “wrist” joints. Accurate measurement of the rotary position of these joints is central to enabling the cobots’ control system to keep track of the spatial orientation of all of its moving parts. This is typically provided through rotary encoders mounted in each of the device’s joints.

Encoders measure rotation and return a digital signal that reports the angle of rotation (absolute encoders) or rate of motion (incremental encoders) to the control system. The ‘right’ encoders for cobots need to be accurate, reliable, and compact, with excellent dynamic response characteristics. They also need to be reasonably priced. POSITAL-FRABA has responded to this challenge by developing new sensing technologies – such as magnetic and capacitive rotary encoders – that provide cobot manufacturers vital feedback for closed-loop control systems. In order to ensure that these devices meet the needs of cobot builders, POSITAL-FRABA offers products with a wide range of performance characteristics, communications interfaces and physical configurations.

POSITAL‘s kit encoders offer a unique combination of accuracy, reliability and cost efficiency. Absolute measurement versions provide 17 bit electrical resolution and multiturn position measurements with a range of more than one million revolutions.

  • Electrical Resolution: Up to 17 Bit, Multiturn: Up to 32 Bit
  • Accuracy: 0.1°
  • Compact Size: 36 mm diameter, 24.2 mm Height
  • Operating Temperature: -40 to +105°C

The Engineering Edge – Application – Trunnion Grinding Slide for Oil Field

 

We are shipping another slide today for the oil patch. When Weir Oil and Gas called with a slide application that required special engineering, LM76 was all ears – as it was right up our alley. This slide is a Trunnion Grinding Slide which has a 56HP motor running at 3500 RPM mounted to the Y Axis – with a 12″ grinding wheel attached. The X Axis (52″ Stroke) runs on 440C stainless linear ball bearings that have special beryllium copper scraper seal cartridges while the Y Axis (4″ Stroke) employs profile rail guides with double scraper seal kits. Our customer did not want protective bellows so we had to ensure grinding debris would not cause bearing or screw/nut failures. On both axis, we employed our proprietary “Polymatrix, Double Preloaded Nuts” as opposed to recirculating ball nuts. Why LM76? Good question…we were the only company that got back to them with a thoughtful solution.

Motion Control – Compact Linear Induction Motor Is Available from H2W Technologies!

H2W Logo

Santa Clarita, CA —– Motion Control – H2W engineers have developed a compact Linear Induction Motor (LMAA-04-01) that can generate 10.6 lbs [47 N] at a 15% duty cycle. Operating at 208 VAC 3-phase 60 Hz, the synchronous velocity of this LIM is 160 in/sec [4 m/s]. This LIM was designed for high speed operation; however, it can also be operated at stall (zero speed) to produce static thrust. This motor is encapsulated using high temperature 350°F [176°] potting compound which protects the components and seals it from moisture.

A non-contacting, high speed, linear motor measuring just 8.7 in. [223 mm] long x 3.0 in. [75 mm] wide x 1.7 in. [43 mm] high this LIM operates on the same principal as a rotary, squirrel cage, induction motor. They are typically used in applications that do not require positioning.

The 3-phase coil assembly can be directly connected to the AC line for single speed applications or to an adjustable frequency drive for variable speed control of the motor. The motors are reversible and can also be dynamically braked.

The laminated coil assembly is used in conjunction with a customer supplied aluminum and steel reaction plate to produce a force. A customer supplied bearing system is required to maintain the .125 in. [3.0 mm] air gap between the coil assembly and the reaction plate. The length of the reaction plate is typically equal to the coil assembly length plus the stroke.

Advantages:

  • Only 2 Parts
  • Wide Speed Range
  • No Maintenance
  • Non-contact
  • Ease of Control and Installation

Typical LIM Applications:

Motion Control – Custom Linear Mechanisms

Custom Linear Mechanisms from Steinmeyer …

Welcome to Where Precision Is.  You Can Turn to Steinmeyer for Design and Assembly of Custom Linear Mechanisms for your Precision Positioning Systems
Modern mechatronic systems consist of numerous precision components that must be assembled in complex configurations. Here, every detail counts.Steinmeyer Mechatronik, a division of August Steinmeyer GmbH, offers design and assembly services for a variety of demanding applications.We have deep experience in medical devices, laboratory instrumentation, optical inspection & semiconductor positioning. Our engineers can implement your finished design or optimize your concept.

For Example …

Zoom Unit

Sliding axes for the adjustment of two optics

Two lenses must be positioned relative to each other and also positioned together. Since the unit is exposed to stray radiation from the exposure process, lubrication must withstand these conditions in the long term. The basic solution consists of two sliding axes on a common guide system. Two moving sliding carriages have three carriages each, which allows them to move partially within each other in order to bring the lenses together as closely as possible. The drives consist of smoothened ball screw drives driven by a direct current motor with a rotary encoder. The motor encoder assembly is designed to be interchangeable for easy maintenance.

Designed for extremely dry environments

By choosing a PFPE-based lubricant and a special surface coating, the requirements for clean room compatibility and UV resistance were met. All accuracy-relevant parameters are verified by a measuring station after installation. This measuring station is located in the clean room and records accuracy, repeat accuracy, straightness, evenness and current consumption. Additional tests are performed to ensure minimum clearance in the bearing and smooth running of the drive system.

Steinmeyer has decades of experience in precision assembly. All of our systems, whether single or multi-axis, are manufactured carefully. Our high standards, monitored continuously through vigorous quality systems, are evident in every assembly we produce. We pay attention to every detail.

Motion Control Application – Intelligent robot systems are increasingly being used in disaster control, rescue missions and salvage operations!

After the severe earthquake in Japan and the subsequent nuclear disaster in Fukushima, Quince managed to reach the upper floors of the ruins of the power plant. There it measured the radioactivity levels and sent HD images to the world outside.

Wherever it is too dangerous for humans. Robots that can look for survivors after an explosion, an earthquake or other natural disasters, providing humans with a view of inaccessible areas. Powerful EC motors from maxon motor give the Japanese rescue robot “Quince” its drive.motion control application robot Quince

 

Maxon Logo

Fall River, MA — Motion Control Components Application – Robots that are used in disaster areas have to have a very high level of adaptability. They have to be fairly small, not too heavy and maneuverable enough to get through cracks or narrow spaces to reach areas deep inside a building. Furthermore rough terrain should present no problem. These rescue robots enter and explore buildings to determine if there are gases, radiation or other life-threatening hazards, before human rescue teams can search the area. Quince has proven that it fulfills all these demands. After the severe earthquake in Japan and the subsequent nuclear disaster in Fukushima, Quince managed to reach the upper floors of the ruins of the power plant in June 2011. There it measured the radioactivity levels and sent HD images to the world outside (To see video – CLICK HERE). The robot was able to supply valuable information from areas where no human can set foot.motion control robot goes down stairs

Quince weighs 27 kg and is equipped with four moving caterpillar drives (flippers). These flippers automatically adapt their angular position to the surface underneath – regardless of whether the robot is climbing steep stairs or crossing rough terrain. Correct ground contact is a very important prerequisite. This contact is accurately analyzed by measuring the power consumption of the flipper motors. Furthermore PSD (Position-Sensitive Device) sensors on the front and rear flippers measure the distance to the ground. In addition to a gripper arm (see fig. 2), two laser scanners can also be attached to the robot. These scanners are capable of accurately capturing the structure of the terrain.motion control robot navigates rough terrain

Additionally Quince is equipped with a “bird’s eye camera” and can travel quite fast, at 1.6 meters per second. The operator that controls the robot has to tell it which direction to take, but the robot itself determines the optimal flipper positions for crossing various surfaces, for example stairs. Newer Quince motors have additionally been equipped with a device for collecting radio-active dust or ultra-fine particles, as well as a 3D scanner. To ensure that no robot is lost, a connection to a wireless network is possible, which is the only way to navigate the robot if the connection cable breaks.

The rescue robot was developed by Eiji Koyanagi, Vice-Director of the Chiba Institute of Technology Future Robotics Technology Center (fuRO). Koyanagi started his career as a teacher – at the age of 51, he became a professor. This means that he has a completely different background than other researchers in the field of robotics. Quince has been specially designed for extreme conditions in environments where it would be too dangerous for humans. Therefore its main area of application is disaster areas. “When you develop a robot, you first have to consider the tasks that it will perform later. That is the biggest challenge,” explains Koyanagi. Hitherto eight Quince robots have been built. But before this could be done, all components had to be 100% functional. To this end, various trials were run in the large “Disaster City” training area in College Station, Texas. Quince was the only robot that successfully completed the entire obstacle course at the site as part of a RoboCup contest. In preparation for using the robot inside the Fukushima Daiichi nuclear power plant, several specific customizations were required. “The conditions in the nuclear reactor buildings are very tough. If we had attempted to send Quince in without modifications, it would probably have met its end,” says Koyanagi. Therefore the robot had to be able to survive a fall from approx. 2 m high unscathed, and had to be largely maintenance-free.

Powerful motors to beat every obstacle

Motion Control -Maxon Motors used in robot Quince

Where the motor selection was concerned, fuRO required absolutely reliable drives. The motors have to provide high power and high efficiency, yet be small and light. These requirements were precisely met by maxon motors, explains Koyanagi. Six powerful maxon motors drive the robot. The brushless EC-4pole 30 direct current motors each provide 200 W; two of these have been installed in the two main chains. The powerful 4-pole units give their all when Quince maneuvers its way across uneven terrain. Four additional motors (EC22) drive the moving chain drives (flippers). These can automatically adapt their angular position to the surface below. The 3D scanner unit of Quince is moved to the right position by an RE-max 24. Thanks to the special winding technology and the 4-pole magnets, the maxon EC-4pole drives are unbeatable when it comes to delivering the highest driving power per unit of volume and weight. The motors have no cogging torque, high efficiency, and excellent control dynamics. The metal housing additionally ensures good heat dissipation and mechanical stability. All motors of the chain drives have been combined with the GP32HP (High Power) planetary gearhead with MR encoder. This gearhead was customized by installing a large ball bearing and a reinforced motor shaft. With this power pack, Quince has no trouble managing almost any obstacle.
