Cheetah 2 Robot Now Leaps Obstacles To Get You

MIT's Cheetah robot, now upgraded to Cheetah 2, is now able to get you even if you put obstacles in its way.

Now, the robot can "see," with the use of onboard LIDAR—a visual system that uses reflections from a laser to map terrain. The team developed a three-part algorithm to plan out the robot's path, based on LIDAR data. Both the vision and path-planning system are onboard the robot, giving it complete autonomous control. The algorithm's first component enables the robot to detect an obstacle and estimate its size and distance. The researchers devised a formula to simplify a visual scene, representing the ground as a straight line, and any obstacles as deviations from that line. With this formula, the robot can estimate an obstacle's height and distance from itself.

Once the robot has detected an obstacle, the second component of the algorithm kicks in, allowing the robot to adjust its approach while nearing the obstacle. Based on the obstacle's distance, the algorithm predicts the best position from which to jump in order to safely clear it, then backtracks from there to space out the robot's remaining strides, speeding up or slowing down in order to reach the optimal jumping-off point.

Fans of Neal Stephenson's 1992 novel Snow Crash may recall the Rat Thing:

The body is Rottweiler-sized, segmented into overlapping hard plates like those of a rhinoceros. The legs are long, curled way up to deliver power, like a cheetah's. It must be the tail that makes people refer to it as a Rat Thing, because that's the only ratlike part - incredibly long and flexible.

William Gibson fans will chide me if I forget the slam hound from Count Zero (1986).
