Requirements:
Robot fits in 4" diameter tube
Drops from a height of 1000'
Must travel 10meters after landing on ground.
Ground is tall grass (6" high), along with other small obstacles.
Currently my idea is to use a single-track design. Like a tank, but there is only one tread. A parachute is used to slow the robot down, and once on the ground it releases the parachutes and chugs away with the single tread. Currently the problem with that design is that if it lands on its side, it will not work.
There has to be something to laterally stabilize it. I was thinking small poles stick out on the side, but is it possible that the grass will get caught on the poles and prevent the robot from moving?
