|Can you build an all-wheel-drive space rover from standard parts?|
Yup … at least the drive system. Using low-cost, standard motion-control parts from the FAULHABER Group/MICROMO and controlled with conventional components, the eight-wheel Shrimp Rover climbing concept was built to carry instrumentation for space travel missions and challenging Earth-bound applications such as minesweeping. Read all about creating the off-the-shelf drive system for this rover.

|Eccospheres aim to prove their heat-shielding mettle on Mars mission|
High-performance glass microspheres from Trelleborg Offshore were specified by Lockheed Martin for use in the composite aeroshell system used to protect the car-size Mars Science Laboratory (MSL) Curiosity rover launched last November. The aeroshell is a blunt-nosed cone that encapsulates and protects the rover during its deep-space cruise to the red planet.

|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.

|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.
