  1. Remote Control of an ATV Team members: Bryce Aberg Eduardo Barcellos Faculty: Stacy Wilson Ron Rizzo

  2. Background Information • Originally developed by WKU’s Engineering Manufacturing • Commercialization Center (EMCC) • Used as a mobile platform to detect subsurface voids • Applications include: Sinkhole detection, tunnel/bunker detection

  3. Project Objectives • Remote control of the steering, throttle, choke, brakes, start/stop • of an ATV • Communicate through WiFi to a myRIO that will control these • systems by using shared variables.

  4. Block Diagram

  5. Haydon Motor Controller (Throttle, Choke) • Step-motors need a driver • Clipper has internal and externalcontrol • Stepper-motors can be controlled by sending a clock signal • (10Hz – 2KHz) from the myRIO to the Clipper • Inputs on the Clipper for direction, clock, motor enable

  6. Sabertooth 2x25 (Steering) • Linak actuator controls steering, requires 20A • Sabertooth 2x25 motor controller can control up to two 25A motors. • Two control options: Serial and analog on S1 and S2 • For analog: • <2.5V on S1: Backwards • =2.5V on S1: No movement • >2.5V on S1: Forwards

  7. Relays (Brakes, start/stop) • Zettler relays used to control solenoid actuator • Solenoid is connected to thick wire to control brakes • Another relay controls the engines ignition

  10. Shared Variables • Variables that can be shared between programs or across a network • Several types, this project will be using network-published • shared variables • Can be changed using an app on the iPad (Data Dashboard)

  11. Current Status • We have almost all the basic functions complete • All motors and relays can be controlled through LabView • No wireless connectivity • Wiring system is a mess

  12. Future Goals • Update code to use event handling • Implement shared variables in LabView • Design board that will connect to myRIO to replace the stock board • Streamline the wiring on the ATV
