Step-by-Step Instructions
1
Print the Parts
Download the open-source STL files from GitHub and print the head, body, legs, and feet using a 3D printer.
2
Assemble the Hardware
Insert the servos into the body and legs. No soldering is required if you use their expansion board.
3
Upload the Code
Connect the Arduino to your computer and upload the open-source Otto dance or obstacle-avoidance code.
Why It Works & Notes
Parent Note:
Great first robotics project. Requires basic snap-together assembly and uploading provided code via Arduino IDE.
