Licence
The engine in this project (sdk/, package name ohho) is Apache-2.0. That file is in the private workspace. It is not published on GitHub yet, so this page does not link a blob that would 404.
The public robot repository is ohho-robotics/OmniBot. The public ohho-sdk repository is a TypeScript client, not the Python engine, and it does not currently include a LICENSE file.
Do not treat a repository as open source until its own licence file says so.
