Robot Platforms for Learning
Comparison of robot arms and systems for data collection and imitation learning.
Overview
Choosing a robot for learning depends on cost, DOF, teleoperation support, and dataset availability. Below is a comparison of common platforms.
Platform Comparison
| Platform | Approx. Cost | DOF | Data Collection |
|---|---|---|---|
| WidowX 250s | ~$5–8K | 6 | BridgeData, Open X-Embodiment. Low-cost, widely used. |
| ALOHA (bimanual) | ~$20K | 2×6 | Bimanual teleop. Stanford datasets. Trossen. |
| Mobile ALOHA | ~$32K | Mobile + 2×6 | Whole-body. Cooking, mobile manipulation. Open source. |
| Franka Panda | ~$12–15K | 7 | Force control, compliance. Research labs. |
| OpenArm | — | 6 | Data-centric design. See OpenArm. |
