Do you have an arduino robot you already made that you wish to integrate? By connecting a raspberry Pi loaded with our software over USB, you can easily get your robot to work on the site.
Here is an example of the interface protocol for serial commands:
controller.py can send commands from the Raspberry Pi to another device using a 9600 baud serial connection. Configure with command line arguments to controller.py --type serial --serial-device /dev/ttyYOURDEVICE Commands have the form of lower case text terminated with the two characters: \r\n Custom commands configured in robot profiles will be sent (lower case) and you can process them as you wish. Examples of commands: "l" Left movement pressed "r" Right movement pressed "f" Forward movement pressed "b" Back movement pressed "brightness_down" Brightness control pressed "brightness_up" Brightness control released "leds ff8000" LED color set by hex values, red=ff, green=80, blue=00
Here is an example of how this is handled on the Arduino side:
Here is another example one of our Robocasters uses for driving 2 DC motors
