Anti-Creep Mechanism Enables Ultra-Precise Motor Table Positioning

Motion control is essential for the digitization and automation of high-tech equipment, but bearings remain basic to frictionless movement. Bearing Engineers, a bearing distributor, recently changed its name to Motion Solutions (Aliso Viejo, CA) to better reflect their evolution into a custom designer of motion solutions for high-tech electromechanical systems. Developing custom solutions has lead to developing lines of proprietary products that the company manufactures in-house.

Vibration Sensors Add New Touch to Prosthetics

The sense of touch is complex, and an instructor at the University of California – Santa Barbara (UCSB) has the technology to prove it. Yon Visell, assistant professor in the Department of Electrical and Computer Engineering, and his students designed an apparatus that captures the unique vibration patterns associated with touch-specific actions, from gripping a coffee mug to tapping on a flat surface. The findings could support new applications in prosthetics, robotics, and virtual reality.

Solar Orbiter Instrument Filters Powered by Brushed Motor

maxon RE 13 brushed DC motors maxon precision motors Fall River, MA 508-677-0520 www.maxonmotorusa.comIn 2018, the European Space Agency (ESA) will send the Solar Orbiter into space. A joint project of the ESA and NASA, the Solar Orbiter will be an important milestone in the exploration of the Sun. An American rocket will take the probe into space, and it will travel for three years until it can begin its work.

Customized Drone Maps Glaciers

Using a custom-designed drone, a researcher from The Ohio State University mapped glaciers and wetlands in Peru’s Cordillera Blanca mountain range. Despite a discovered drop in glacier growth, the findings from the unmanned aerial vehicle (UAV) revealed a slightly more optimistic picture of the region’s water supply, which relies in part on the ice formations.
