Linear guides that depend on metal-to-metal contact require frequent lubrication to maintain smooth, quiet operation. Thermoplastic sliding elements run smoothly and quietly without lubrication, even in moist environments.
Adjustable clearance lets engineers use the guide in either fixed or floating carriage applications. Currently available in 20-, 25-, and 30-mm sizes, a 15-mm size will be available in the near future.

Festo's BionicKangaroo combines pneumatic and electrical drive technology, plus very precise controls and condition monitoring. Like a real kangaroo, the BionicKangaroo robot harvests the kinetic energy of each takeoff and immediately uses it to power the next jump.
Design News and Digi-Key presents: Creating & Testing Your First RTOS Application Using MQX, a crash course that will look at defining a project, selecting a target processor, blocking code, defining tasks, completing code, and debugging.
These are the toys that inspired budding engineers to try out sublime designs, create miniature structures, and experiment with bizarre contraptions using sets that could be torn down and reconstructed over and over.
PowerStream is deploying the microgrid at its headquarters to demonstrate how people can generate and distribute their own energy and make their homes and businesses more sustainable through renewables.
