2. CRC Card MovesCollaborations Responsibilities 1.Detect Obstacles 2.Detect Remote control Signals 1.Turn following on 2.Switch between following & running away 3.Move getIR getObstacles motors Alex coded main following functionality Nischal added code to detect signals from TV remote & switch between following & running away.

3. Controlling Scribbler  Scribbler has IR receivers  Original intent was to detect specific button presses on the TV remote to control robot  TV remotes use pulses  Robot detects any button press as “1000”  Used remote as toggle switch

4. Controlling Scribbler  Robot is on “standby” to begin with  On detecting a remote press, robot enters “follow mode” Robot follows any obstacle placed before it  On subsequent remote presses, robot toggles between “follow mode” and “run away mode”

5. Lessons Learned  This project taught us the basics of how to use sensors to detect a robots environment  Also, it taught use how we can interact with a robot to change its behavior
