Zero-Turn Mower Research Platform 1 Sense the state of the surroundings and the mower 2 Drive with an informed view of one’s surroundings 3 Record driving dynamics for future analysis 4 The sensor suite records the dynamics of the mow- Increase safety and driving performance Drive by wire capability allows implementation of er while driving, giving Ariens the ability to investigate 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. System recognizes dangerous slope Warns operator with visual readout Implements automatic safety response Faculty Advisor: Ariens Scope Team: Aaron Hoover Andrew Carmedelle Tim Raymond Sponsor Liaison: Casey Landey Josh Wilson Eric Jones
