This repository contains executable files that Robotheca doesn't check. Only run them if you trust the creator.

Which files (59 scripts, 37 programs or installers, 6 firmware images)

Suggested by Robotheca, created by @golaced (opens in a new tab), from github.com/golaced/OmniBotSeries-Tinker (opens in a new tab), pinned to commit 075e79c (opens in a new tab). You buy the parts yourself; Robotheca doesn't sell robots.

What to buy

Wiring and electronics

Notes written by Robotheca from the project's documents

Main parts

  • Brushless motors drive the robot's joints.
  • Odroid C4 onboard computer runs the control policies.
  • ESP32-S3 based remote controller with a 2.4 inch LCD module (from the ESP32 example README).
  • Custom Altium PCBs include power boards (power-one, power-two, power-four, power-one-usb), a core board, a debug board, an external CAN board, and a remote board with a USB converter.
  • Bill of materials is maintained externally in linked documents rather than in the repository.

Connections

  • Power boards in the OmniBotHub design are split into several variants, indicating power distribution across the robot.
  • An external CAN interface board (omnibothub-extcan) suggests motor communication over CAN bus.
  • A debug board and USB converter board are included for programming and communication with a computer.
  • Detailed pin and connector wiring is not described in the provided documents; refer to the Altium schematics and linked guides.

What it can do

Written by Robotheca from the project's documents
  • Bipedal walking gait trained with reinforcement learning and transferred to a real robot (sim2real), described as closely matching the BDX style gait.
  • Runs trained locomotion policies (TVM) on an onboard computer (Odroid C4).
  • Locomotion with reinforcement learning is shown in the Ctrl package README, with real-robot performance demonstrated in an external video.
  • Optional large language model voice interaction via installable Xiaozhi AI modules.
  • Remote control handled by a separate ESP32-based remote with an LVGL display.

Works with AI

Found by Robotheca in the project's files at commit 075e79c, its robot.yaml and Robotheca's notes on its documents. Never guessed; Robotheca doesn't run the code.

How to run it

Written by Robotheca from the project's documents.

  1. 1Refer to the linked software guide describing how to run TVM policies on the Odroid C4 onboard computer.
  2. 2Training your own policies uses IsaacGym according to the linked repository document.
  3. 3The OmniBotTele ESP32 example documents that the code is built for a Zhengdian Atom ESP32-S3 development board, with LED on IO4 and an LCD module; flashing steps are not given in the provided text.

Software that runs on this robot
