Compared to many six-strut hexapod configurations, this five-strut design increases the ratio of working space to build volume while providing more residual stiffness at high swivel angles.
In addition to its 5-axis machining capability, this pentapod design can also swivel through ninety degrees. The machine controller, however, accepts conventional co-ordinate information supplied by a normal numerical control program. Bosch Rexroth MHS 40 direct drives with hollow-shaft motors raise and lower the spindles. Compared to toothed-belt systems, the direct drive gives a stiffer design with fewer parts, increasing reliability. As there is no belt, no retensioning is required. Machining applications for the pentapod include models for prototypes and forms for castings.

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.
