Tbot Linear Robot systems with fixed motor mounting are perfect for pick and place

Macron Dynamics' belt-driven X/Z T-Bot systems (TBG line) are perfect for pick-and-place processes. The simple design, where a single belt drives both axes, means there is no need for costly cable carriers. This type of motion can be used for anything pick-and-place oriented, and the extruded construction means it can scale to virtually any application. The architecture of the line allows for smaller travel heights for the Z axis, providing a more compact structure that is easier to integrate into existing designs. Models available to handle max loads from 10 to 100 lb.

Get a grip: GM and NASA create robot 'power' glove that may help human assembly-line workers

Feel the force. Feel the power.

Robotic glove technology developed from a partnership between General Motors and NASA for use on the International Space Station is finding new life on Earth in health care, manufacturing, and other industrial applications. The project is made possible through a licensing agreement between GM and Bioservo Technologies AB, a Swedish medical technology company.

Working with GM, Bioservo will combine technology from its SEM Glove (Soft Extra Muscle) technology with the RoboGlove, a force-multiplying battery-powered wearable developed by GM and NASA during a nine-year collaboration that included the launch of the humanoid robot called Robonaut 2 (R2) into space in 2011.

Essentially a robot in your hand, the RoboGlove uses leading-edge sensors, actuators, and tendons that are comparable to the nerves, muscles, and tendons in a human hand. One design requirement for the R2 space robot was to operate tools designed for humans, and developers achieved unprecedented hand dexterity. That technology was applied to the RoboGlove.

NASA described the glove technology's capabilities in 2014 like this: "An astronaut working in a pressurized suit outside the space station or an assembly operator in a factory might need to use 15 to 20 lb of force to hold a tool during an operation. Use of the Robo-Glove, however, would potentially reduce the applied force to only 5 to 10 lb."

The original prototype weighed around 2 lb, including control electronics and a small display for programming and diagnostics. Pressure sensors, similar to the sensors that give the R2 robot its sense of touch, are incorporated into the fingertips of the glove to detect when the user is grasping an object. A lithium-ion battery, like those used for power tools, is used to power the system. It is usually worn on a separate belt, but eventually it could be built into the top or the wrist of the glove.

Bioservo aims to take the glove technology one step further by developing a lighter, smarter grasp-assist device for industrial use that could increase human operator efficiency while reducing fatigue in hand muscles. Research shows fatigue can occur within a few minutes of continuously gripping a tool. The company also aims to vastly expand the glove's potential wearer base, with a focus on the medical-assist market.

"Combining the best of three worlds -- space technology from NASA, engineering from GM, and medical technology from Bioservo -- in a new industrial glove could lead to industrial-scale use of the technology," said Tomas Ward, CEO of Bioservo Technologies.

Ward described the glove's capabilities as a major step toward introducing soft exoskeleton technology globally.

GM intends to be the first U.S. manufacturing customer for the refined robotic glove and will test it in some of its plants. Bioservo will make and sell the new glove for a variety of uses, including medical rehabilitation and any place or repetitive task where additional gripping strength is needed.

"The successor to RoboGlove can reduce the amount of force that a worker needs to exert when operating a tool for an extended time or with repetitive motions," said Kurt Wiese, vice president of GM Global Manufacturing Engineering.

GM briefly tested RoboGlove in a preproduction plant before looking for a partner to help refine it to fit different hand sizes and address other issues.
