Robot: “Emerson” Autonomous robot capable of using wall outlets to recharge itself

Sensors Bump sensor plates –Radio Shack switches IR sensors –Sharp medium-range sensors (obstacle avoidance) –Sharp short-range sensors (wall-following) Battery voltage –Voltage divider Electromagnetic –Op-amp detector circuit with signal conditioning

Actuators Y-Z stage –Linear actuators Bipolar stepper motor Hacked servo

Behavior Obstacle Avoidance –Bump sensors LS, LF, RF, RS differentiation –IR Detect obstacles Fuzzy logic speed control Wall following Detect wall outlets

Conclusion Problems with linear actuator fabrication slowing things down, but should be running by Demo Day Left to do: –Finish actuator –Integrate software behaviors –Refine
