Problem Overview
• RoboDog is built on an AmigoBot with a top-mounted Kinect sensor
• Capabilities– Wander– Identify tennis ball– Grab tennis ball– Identify human (through marker)

Implementation Overview
• Sensing– Ball/Human Detection– Obstacle Detection– Odometry of AmigoBot
• Thinking – State machine
• Acting– Wander Straight– Wander Turn– Drive to Ball/Human– Manipulate Ball

Conclusion
• Sensing: detects ball and human• Thinking: state machine• Acting: retrieves the ball• Successful implementation and integration of
all sub-components• It works!
