Why it scores 69

It measures the published files, not the robot · How we score

69/100

Buildable with some effort

How complete the published files are for rebuilding this robot, measured by Robotheca at commit 2dad901. It isn't a rating of the robot. Counted out of 80 points and scaled to 100: the parts that don't apply to this robot are left out.

How to run it: Robotheca's summary

Written by Robotheca from the project's documents, not by its creator.

  1. 1Clone the repository with git clone --recursive, or run git submodule update --init to fetch ArduSnake.
  2. 2With PlatformIO, run pio run in the firmware folder to build, or pio run -e calibration -t upload to upload one sketch.
  3. 3With the Arduino IDE, copy lib/Zowi and external/ArduSnake/ArduSnake into the sketchbook libraries folder, install the Servo library, and open an example sketch.
