Algodoo

This is a design i am prototyping called the MRT, or moon rover tank. Weighing in at just a little over one ton, this tank is fast and agile, and provides excelled mobility over its rocker-bogie counterparts. The reason for the turret is not for weapons but to conceal and protect the vital various hard drives inside ( hard drives not included, make your own). The information from the IR sensors at the front of the turret is recorded as a video file that is transmitted from the satellite to the space station. Tools and various items are located on the side of the vehicle. Remember, this is my concept of the functions of the vehicle IF it were a real vehicle.
Controls:
d = forward
a = backward
w = brakes
