  2. Main Goal Design and Build a Remote Control Lawn Mower

  3. Design Specifications Overview 1. Turn a push lawn mower into a remote control lawn mower 2. Power 3. Direction 4. Speed 5. Safety shut-off

  4. 1. Remote Control Lawn Mower Battery Powered Rear Wheels Swivel wheels

  5. 2. Power Lawn Mower engine (GAS) 12 Volt Battery, drives circuitry and motors

  6. 3. Direction Skid steer maneuvering, through turning the wheels in opposite direction causing the lawn mower to swing in either direction (left or right) without going any distance.

  7. 4. Speed PWM (Pulse Width Modulation) ~ A way of providing intermediate amounts of electrical power between fully on and fully off, done by changing the duty cycle of the pulse.

  8. 5. Safety Shut-Off The lawn mower engine will shut off when the receiver loses signal. Remote control shut-off switch Manual switch

  9. Timeline May 12, 2010 Decided to design a remote control lawn mower. June 4, 2010 Met and decided on the design specifications and goals of this project. June 20, 2010 Worked on how to implement our goals. Gathered ideas on what design procedure to use. July 20, 2010 Bought a used push lawn mower. July 28, 2010 Decided to use parts from an old powered wheels hummer Took the lawn mowers handle and rear wheels off.
