Drogerdy - Raspberry Pi Controlled Tank Bot

thingiverse

The second prototype from the jRobot project takes shape in this little tank bot that gets by with just a few simple components to get everything done. I've given it an update to make it more adaptable, and the tracks now grip even better too! Watch this demo video: https://www.youtube.com/watch?v=MJIx0cyOL3s&feature=youtu.be . The jRobot project makes it easy for my students to plug in any of their Raspberry Pi's to a robot base and start programming right away. This particular prototype takes advantage of the MCP3008 ADC so the RPi can communicate with lots of different kinds of analog sensors including the Sharp 2Y0A02 Infrared distance sensor. It also uses the same pin-based docking system that was used in the Apogee Robot (http://www.thingiverse.com/thing:648394). Instructions Watch this demo video for an idea of what you're making! https://www.youtube.com/watch?v=MJIx0cyOL3s&feature=youtu.be . You'll need 26 tracks on each side, held together by 35mm long, 2mm stainless steel rods. These same rods are also used to keep the RPi secure in its slot. To assemble each set of tracks, you will need: 2 cogs, 2 inner cog brackets, 2 outer cog brackets and 1 track mid frame (the inside frame still needs some testing though). Then attach the two track assemblies together using 2 body parts. Make sure the motors are fitted to their slots first - I use no-name, yellow geared ones from eBay for this model. You'll find them at: http://www.ebay.com.au/itm/1pcs-Anti-interference-f-Robot-Smart-Car-Chassis-DIY-DC3V-6V-DC-Geared-Motor-TT-/291314517942?pt=AU_B_I_Electrical_Test_Equipment&hash=item43d3b2c7b6 You can install the motors after gluing all these pieces together using five minute epoxy - adding a bit of steel to the ends will prevent them falling apart.
