I used a motorcycle type bullet nose quick-connect at the end of the 6 inch wire, but a 3/16 spade quick-disconnects are more readily available. Solder a 6 inch wire to this strap and cut a slot in battery housing to route the wire out. Separate battery pack halves and with a multi-meter find the battery connecting strap providing +12 VDC output. Thread a 3/8-24 hex nut onto the motor drive shaft followed by driving link, and lastly use a small washer and reverse thread screw to complete the attachment of the driving link to the motor shaft. Use two #4 washers to move the disk from the end of the motor a little bit, see photos.
Second using Dremel tool or round file, cut 2 semicircular grooves on either side of “double D” section to accommodate the mounting bolts, see photos.įor the jaw opening mechanism motor you’ll need to reattach the drill chuck.įor the neck motor reattach the black cover disk. First using Dremel tool or file remove semicircular rib at the top of one of the “double D” the sections. Two additional modifications are required to the front “double D” black plastic section of the drill.
For this application I used an O-ring, rather than set-screws, to lock up the gear box torque limiter because it was cheap and simple. See how-to link below for removing motors from electric drills.
Safety First – the robot throws Tic-Tacs at high velocity, stay out of harms way by always standing either in front of or behind the robot - never at the side of the robot. Hopefully this serves as a “starting point” to perhaps motivate makers and inventors to create even better robots to compete in entertaining physical challenges such as those presented on “Minute to Win It” game show.

You’ll notice a few extra holes here and there - that reflects the trial and error development process. Construction requires basic circuit building and wood and metal-working know how – mostly drilling and sawing – no welding or machining required. Labor cost only $2 assuming I pay myself 5 cents an hour. Main components: Harbor Freight cordless electric drill motors (2), automotive wiper motor, Picaxe 18 M2 microcontroller, wood and metal components made from stuff available at hardware or home improvement stores. Mad Dog Robot functions: mechanical jaw opens / closes, and tightly holds the ruler, simulated neck rapidly tilts ruler clockwise / counterclockwise about 45 degrees from horizontal, and finally a powered platform moves robot forward / backward to pickup and replace the ruler.

Here's a DIY robot designed to compete in "Mad Dog" challenge as seen on NBC game show "Minute to Win It." In "Mad Dog," two Tic-Tac boxes are mounted to each end of a 12 inch ruler contestants pick up the ruler with their teeth and have to shake out all the Tic-Tacs within a minute.Īny universal IR remote control which can produce Sony TV IR signals can control the Mad Dog Robot - either with individual functions or macros running pre-programmed command sequences. After seeing IBM computer Watson beat two former champions in Jeopardy earlier this year, I wondered if a simple robot could compete with people in more physical challenges.
