An arduino power quadruped robot sprinter/walker based on the designs by Sebastian Coddington. This version uses a different codebase and has some modifications to the board and battery mounts.
For the original robot, more detailed build and construction information can be found at: https://www.instructables.com/id/GorillaBot-the-3D-Printed-Arduino-Autonomous-Sprin/
All new models were created in Tinkercad and exported in STL format.

I chose to drive the robot with the ArduinoBlue mobile app and library. The joystick is preconfigured (for steering and throttle) but you will need to setup buttons initially to drive the remaining functionality. The following list of functions are available to setup as buttons within the app:
| ID | Name | Description |
|---|---|---|
| 1 | Autonomous | Toggle on/off autonomous mode |
| 2 | Stand | All legs in an up position |
| 3 | Lay | All legs in a down position |
| 4 | Sit | Back legs in down in a sitting position |
| 5 | Crouch | Front legs in down in a crouching position |
| 6 | Tilt | Tilting each leg in a clockwise rotation |
| 7 | Strut | Strut walk forward for a few paces |
