The thing is a robotic rover that looks like something that would roam the moon. The original launched in 1979, sold through 1982, and was one of the first computer controlled toys. The device has a control pad in the back of the vehicle that you can program to complete tasks.
When you hit the go button on the robot, you can watch to see if the bigtrak robot can make it though the task you programmed it for. The new version is about half the size of the original and will go on sale this summer for $39.99. Accessories including a digital camera will be offered.
