This Is a remote-control car project that had as an objective to climb a 35-degree slope, lift a broom-stick and pass under it, and release a golf ball into a hole/goal.
The car uses standard sized servo motors that were modified for full rotation, and are meant to be between 5-12 volts. The motherboard is a pollulu microcontroller and needs to be powered by a 6V battery pack and connected by a usb cable to a computer. to control it, use the python code I provided below (note: the controls are connected to each connection slot for the servo motors, so you might need to play around to find which slot is supposed to be which motor ;) )
The controls in the program are WASD, EQ are also movement just slightly different from the normal right and left, and to lift the bar, it is TG.
Enjoy!
