Open-source models for robotics

Robotics models connect vision, instruction understanding and action: they teach an arm to grasp objects and a mobile platform to navigate. This is a field for warehouses, manufacturing and research projects. Check which hardware the model supports, whether fine-tuning is needed and what the license allows.

Need a model for your task?

An open model can run on your own server: data stays in-house, there is no per-request fee, and the model can be fine-tuned on your documents.

  1. SelectThe model and size for your task and hardware budget
  2. DeployOn your server or in a closed network, with an API
  3. Fine-tuneOn your data, or connect a knowledge base
  4. IntegrateInto your CRM, ERP, bot, website or team chat
