Leaping lizards inspire robot designs University of California, Berkeley, biologists and engineers studied how lizards manage to leap successfully even when they slip and stumble. They found that lizards swing their tails upward to prevent them from pitching head-over-heels into a rock. But after the team added a tail to a robotic car named Tailbot, they discovered that counteracting the effect of a slip is not as simple as throwing your tail in the air.

| Videos+: Technologies and inspiration in action | Geared slewing rings in action iglide® geared PRT slewing rings from igus® are extremely cost-effective and can be used in place of expensive ball bearings or rolling elements in many applications. igus®' standard PRT slewing rings use self-lubricating, low-friction polymer sliding elements in place of ball bearings. The geared version uses a belt, rack, or pinion gear to drive the slewing ring. It is available in plastic, aluminum, or stainless steel, with no minimum order requirements.
