Assuming a finite electric power supply, one should design a control circuit
that would take into account:
Power Available = Power to wheels + Power to blade (or some other cutting
device?)
I am new to this group and am curious how far the group has gotten in
deciding the design goals. Is this supposed to end up like the lawn mowing
robot at Epcot in Disney, Orlando, Florida?
