Here is the result of a Metal detecting Robot that I'm built that is fittingly named: "X-marks-the-Bot" or "Xbot" for short. It's made out of a broken original Xbox I bought from a pawn shop for $15 and a Radio Shack Metal detector I picked up at a garage sale for $5. The primary objective of the Xbot is to cruise around looking for metal then stop and blink when it finds some. I wanted it to be able to function outside so I used geared motors (high torque, low RPM) with some monster truck wheels on it. I placed some high wattage, low resistance Sand Stone Resistors on the Arduino Shield for some current sensing for the motors, that way if the front bump sensor didn't activate then the bot would still be able to sense that it's stuck. I entered this robot in the Arts & innovation category in the 2010 Western Canadian Robot Games and it tied for first place for Technical Merit (Best engineered).
Specs:
Microcontroller: Freeduino SB [Atmega 328] with 16 MHz Xtal from Solarbotics
Microcontroller Shield: Arduino Protoshield kit from Sparkfun
Microcontroller Battery: 2 X 3.7V 1000mAh LiPo from Princess Auto
Motorcontrollers: 4 X TA8428K - 1.5A Single H-Bridge from Toshiba Photocopiers
Motorcontroller Battery: 4 X 3.7V Ultrafire 18650 LiPo from Deal Extreme
Metal Detector: Micronta 3001 from Radio Shack
Motors: 2 X 18 rpm, 23.5VDC Buehler Gearhead motors & 2 X ??? rpm, 12VDC Gearhead motors all from Princess Auto.
Wheels: Mighty Mo's from toy truck at a thrift store
Hubs: made from scrap aluminum pieces
Chassis: Original Xbox with broken disk drive from Cash Canada
