Added 3 Event Controllers that together create a system similar to an automatic gear box. The Rover will now automatically adjust the traction of the wheels and the maximum steering angle based on the velocity of the Rover.

Reworked the conveyors so ice can be put into the O2 generator from either the cockpit or the connector. Bottles can still pass between cockpit and O2 generator as before. Also added a remote control block facing backwards to help with with steering in reverse (for connecting)

Added ice into the O2/H2 Generator

Added a gear system (2 timer blocks) to more easily control the maximum velocity, turn radius and friction of the wheels.
