| Venom does not document very well at all. [[http://www.competitionx.com/pdf/esc/venom-pro-brushless-esc-manual.pdf|This]] is not the electronic speed control (ESC) for our car. The programming is at least similar enough to let our car go backwards. If it is not in the correct mode, the car will only be able to go forwards. How can you go two steps forwards without at least one back? You can't. | Venom does not document very well at all.

| We used an [[http://arduino.cc/en/Main/ArduinoBoardUno|Arduino Uno]] with its [[http://www.atmel.com/Images/doc8161.pdf|AtMega328 microcontroller]]. 90% of the information on the Arduino board is irrelevant if you're just using it as a platform for the AtMega but the schematics are there. The most significant detail is the connection between the raw AtMega pins and the I/O pins of the Arduino. | We used an [[http://arduino.cc/en/Main/ArduinoBoardUno|Arduino Uno]] with its [[http://www.atmel.com/Images/doc8161.pdf|AtMega328 microcontroller]]. 90% of the information on the Arduino board is irrelevant if you're just using it as a platform for the AtMega but the schematics are there.

| + | {{:projects:CompArchRobit.zip}}: A .zip archive with all of our assembly. robit.S is our main working build. Similarly-named files are backups of partially functional builds or else broken test builds. Running the following from a command line/prompt will build and deploy robit.S on Com10. Change the flash.bat file as needed to reflect the actual Com Port in use. | ||

| + | {{:projects:Robit_Movie.zip}}: An early example of the car in motion. Later builds were less likely to capsize. | ||
