Ball-E by Lee Tsakh EEL5666C Fall 2011 Oral Presentation 2
Operation • Search for a target wearing a certain colored shirt (like bright red) while avoiding obstacles. • Center on the target once it is found. Move to proper distance from target. • Launch tennis ball at target (simulates a difficult shot in tennis). • Report successful launch by flashing an LED at a certain rate.
Sensors • ACMUcam IP Cam to find a target and center on it. • Sonar to determine the distance to a target or an obstacle. • IR to determine if obstacles are close to the sides.
Actuation and Platform • High RPM motor attached to wheel for launcher. Motor sourced from a scooter. • Two wheels and a caster for movement. • Space frame design for platform for maximum rigidity (necessary to support heavy launcher battery and absorb vibrations from launcher).
