Reviewed By Laura J. Martin, MD. May 28, 2010 (New Orleans) -- If your child insists his positive drug test results are a mistake, there's a chance he could be telling the truth.

According to Fox News, MITâs cheetah robot can now jump over obstacles up to 18 inches tall, which is more than half the robotâs height. âOur goal is to use this kind of robot to save lives in a disaster situation,â explains Professor Sangbae Kim.
On the exterior, the cheetah is the most slender of the big cats; its lightweight body (weighing about 80-140 lbs.), small head and long legs are designed for aerodynamics. Structurally, the cheetah has a unique, flexible spine, which allows for extreme flexion and extension while running at top speeds.ike Bolt, the cheetah is a sprinter â not a long distance runner â and can only attain high speeds in short bursts due to the tremendous drain on its energy resources.
