1 Sense the state of the surroundings

driving performance
Drive by wire capability allows implementation of

electronic controls on a previously fully mechanical
wheel position, velocity, accelerations, and driver
system. The drive by wire system is also designed to be
input for every moment of a test run.
easily adaptable to any mower. Stick input to motor
driving output can now be customized for individual
users.
Slope Limiting Safety Mechanism
Drive By Wire
Old Mechanical System:
Tie-rod physically links operator stick to hydraulic pump.
New Drive By Wire System:
(1) Potentiometer senses operator
stick angle.
(2) Motor receives signal and spins
the hydraulic pump.
