Stepper-driven tank platform for remotely operated vehicle

thingiverse

This inexpensive Foscam knockoff WiFi pan-tilt camera was purchased on eBay for approximately AUD$60 with delivery and was strapped onto an RC car chassis. The project involved developing an application for the camera and using Python along with an Arduino. However, the RC car had high speed and poor maneuverability due to a large turning circle. To overcome these issues, a printable tank chassis was designed for better WiFi connectivity and improved control. It has been successfully tested on various terrains around the house. The parts required include the printed tank, two NEMA17 stepper motors, Foscam-knockoff wifi camera, Arduino, Pololu stepper drivers, a 3S 2200mAh battery, a 5W 5V regulator, cardboard, and Velcro. Custom code for the webpage built into the camera and the Arduino code can be found on pastebin, along with a script to decompile and recompile the webUI for the camera and a compiled webUI replacement. The steppers may initially have trouble turning the treads due to friction, but it will quickly wear in and become more efficient. Potential future improvements include integrating stepper mount and spacer pieces into the main beam and creating a printable platform.
