This car is a combination of the RIS 2.0 set with several parts of the #8421 crane set. The back wheels are driven by one motor, which also makes an ‘engine’ run. A motor in the front allows for steering using a rack-and-pinion steering mechanism. A touch sensor in the front detects a bumper press which tells the robot to turn around. This car was designed in June 2006.
I love the old RCX!
