My Junk-Bot

Last year, my 4th grade teacher gave me a used TV remote control as a GAG gift. Over the summer, I thought about what I should do with it. So I thought that it could be used to control a robot with. This robot cost me about $15 total. The reason why it only costs about $15 is because I don't have a lot of money to spend on expensive robot parts. Alternatively, I had to scavenge parts throughout my garage and old projects that were in no use. Here are the parts that I used to build Junk-Bot:

• 2 toy motors
• Used Dave & Buster's arcade card
• Arduino Nano
• Mini breadboard
• YL-44 Arduino speaker
• 44Khz IR receiver
• DC-DC voltage booster
• 2 AA batteries
• Toggle switch
• Wood ball salvaged from a art bracelet (used as a pivot wheel)
• Various electronix components (wires, resistors, capacitors, and transistors)

    Four AA bateries would of been too heavy and would of scraped the ground, so I used a voltage booster to get 5v for the Arduino and motors. The motors do not have wheels they don't have enough power to turn a wheel, so they have little rubber fittings on the output shafts that makes contact with the ground.

    The breadboard is supported by the old arcade card. Which is the frame for the robot. Two transistors controlled by the arduino  allow the motors to be toggled to go forward letting my robot turn left, or right. I used a 44Khz IR receiver and the Arduino IR library to receive the signal from the TV remote and decode them into commands.

I hope you guys enjoyed my robot! Thanks for viewing it!
