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.

Linear motion machine designers are increasingly specifying electromechanical actuators because they are cleaner, easier to control and require less maintenance than hydraulic cylinders. Often ...

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 ...

A continuous passive motion (CPM) machine allows for movement of the joints after surgery. A person may use a CPM machine after undergoing surgery on joints such as the knee or hip. Some people may ...

While this is authentic footage of a genuine product, the "perpetual" marble machine does not operate infinitely without an additional energy source. Rather, it uses batteries and a magnet to create ...
