The approach to developing this iteration of the machine will be different than before and rather than focusing so much on making it autonomous, the focus will be more on what can be achieved with remote control as a rational stepping stone to the ultimate goal of full autonomy.

Stage 1:

• Make the steering and the throttle radio controlled using the onboard quadrature encoders in the motor and linear actuator in combination with inductive sensors to provide 'homing' locations at the mid point of the steering and the neutral position of the throttle. Since the machine is hydrostatic, the throttle moves seamlessly from reverse to forward with a neutral position somewhere in the middle for 'stop' - trying to operate normal manual gears would be much more challenging!

Stage 2:

• Build up a super structure for protecting the internals from the weather and provide mounting points for the various antennae required.
