The benefits and design considerations of lubrication-free plastic components for harsh industrial environments How igus’ continuous-flex cable carriers support rotational motion without slip rings.

Perhaps the most persistent nonsense in physics: the perpetual motion machine. Bad ideas come and go in physics. But there’s one bit of nonsense that is perhaps more persistent than all others: the ...

A continuous passive motion (CPM) machine is a motorized device that passively moves a joint through a pre-set range of motion. These devices may be used after surgery to reduce joint stiffness and ...

Start in a standing position. Grab the handles and bring them up to your shoulders palms facing each other. Squat down to a quarter squat positions; then on the way up, on you will press the weights ...

Efficiently integrating multiple axes of motion within limited spatial and mechanical constraints remains a significant challenge for machine designers. Leveraging compact servo drives with real-time ...

At the turn of the 20th century, the quest for a perpetual motion machine took hold of public imagination. A number of Hoosiers were among those captivated by the idea of creating a perpetual motion ...
