NASA Plans to Fly Helicopter on Mars
There are two robotic rovers traversing and exploring the surface of Mars – NASA’s Opportunity and Curiosity rovers. These rovers, along with two others (Sojourner & Spirit) from past missions, use(d) specially made wheels to get around the Red Planet. Instead of just wheels NASA now wants to try a different way to travel around Mars. […]

Robotic Arm Has Split-Second Timing
Swiss scientists have developed a robotic arm that can catch items thrown at it with split-second accuracy. Researchers say the new invention, described in IEEE Transactions on Robotics, catches various sized objects within 5/100 of a second. The mechanized arm has three joints, a complex and sophisticated hand with four fingers, and measures about 1.5 […]
