Remote Controlled WheelchairWith Collision Avoidance Joseph D’Amato Husein Rashed Steven Ostertag Rohan Vivek T.S. Rockwell
The System • Hardware • The Raspberry Pi (vs Arduino) • Better Support – Python • Better Development Environment – SSH, HDMI Output • Tradeoff – Less ideal for real-time system • User Input • The WiiMote • Bluetooth Interface • Well defined python module available • The Joystick • Inexpensive • USB Interface • Well defined python module available • Sensor Input – Ultrasonic • Used for similar applications in cars (backup sensor) • Cheap • Easy to use • Motor Control • Controlled with PWM from the Pi
The System • System Operation • User in Chair • Operates chair in same manner as standard electric wheelchair • Remote User • Has ability to gain control of the wheelchair while disabling onboard control • Remote user maintains control of the wheelchair until released • Uses directional pad on remote for forward/backward/left/right • Safety • Ultrasonic sensors placed strategically to prevent collisions
Inside The PDF • All this plus… • Major Modules – Contents of each program file • Connections • Future Plans • Reported Problems
