RoboSkills

Python 3.10+ Build Homepage MIT License

RoboSkills is a low-cost, minimal set of agent workflows and tools for robotics.

Workflows

Researched bimanual lifting: 0/2 initially, 2/2 after revision, 3/3 on fresh checks; Blender replay
Auto Research
Improve policies and reusable skills through repeated simulation experiments.

Setting: Auto-research; no direct privileged simulator state in the policy API.

Agent as Policy
An LLM observes an episode and chooses actions turn by turn.

Setting: Zero/one-shot demonstrations; no auto-research.

Two YAM arms thread a rope through a ring in an agent-built simulation
Agentic Simulation
Solve simulation tasks from natural-language instructions.

Setting: Privileged simulator information available.

A DROID demonstration split on a diagonal with its simulation, a Panda taking a marker out of a mug
Real2Sim
Build interactive simulations from demonstrations.

Setting: Physics simulation included.

Studio dance video split on a diagonal with Leonard and Michelle repeating both dancers' motion
Motion Generation
One agent turns a text, image or video request into a motion video.

Setting: Kinematic motion and rendering; no physics.

Features

Low cost

With suitable tools, agents reach comparable performance on fewer, cheaper tokens.

Real2Sim · DexYCB potted meat can Motion Generation · Tennis serve
Cost $0.09. 11% of Codex. Cost $0.00. 0% of Claude Code.

Agent as Policy · RoboDojo stack blocks Auto Research · RoboDojo press by number
Cost $0.16 with DeepSeek. 7% of Claude Code. Both 5/5 on 5 seeds. Cost $0.14 with DeepSeek. 13% of Claude Code. Both 3/3 on 3 seeds.

Minimal

We commit to keeping each workflow under 1,000 lines of code.
