2x Tip 120's, diodes, and resistors - Step up/down voltage regulator - The Arduino was not able to sufficiently power the LED flashlight / laser. Quick release power connectors - Attaches head to the bodies power supply Metal Pushbutton switches with LED - Used for Glowing "eyes" and Arduino reset button.

Ultrasonic Distance Sensor - Used for ultrasonic mapping and object avoidance. (Found mine at KMart) Xbee - *Optional, if you want to talk to devices from the robot (The head is the highest point.) Wire terminal blocks - *Optional either use these or solder the wires to each other. Laser diode - Bonus if it is included in the flashlight. USB Webcam - I choose a Logitech® B910 HD USB 2.0 Webcam LED Flashlight - Easier to use a pre-made flashlight that already has a lense. Motor shield - Various companies make them, Sainsmart has more robust screw blocks. Parts List: Electronics: Arduino Uno R3 - Serial controller with limited programmed logic.
