Summary
A low-cost mobile manipulator designed for indoor home and office environments, with a large open-source ecosystem and teleoperation-based data collection.
Abstract Summary
Key Points
- Compact, safe mobile manipulator designed for indoor home/office tasks.
- Low-cost platform (~$25k) with ROS 2, Python SDK, and teleoperation data collection.
- Telescoping arm spans floor-to-countertop workspace; narrow base navigates homes.
- Widely used in home robotic manipulation datasets and imitation learning research.
- Large open-source community with integrations for LeRobot, ACT, and VLA stacks.
Additional Notes
Setup Tips
- ROS 2 Humble is recommended for the latest Stretch driver support.
- Use the provided calibration scripts to align depth and RGB streams before collecting datasets.
- The arm is intentionally back-drivable; gentle guiding is possible for kinesthetic demos.

AIR-VLA+: Decoupling Movement and Manipulation via Cascaded Dual-Action Decoders with Asymmetric MoE for Aerial Robots
Jianli Sun, Bin Tian, Qiyao Zhang et al. · arXiv preprint · Jun 2026
Aerial manipulation systems have long suffered from representation coupling in end-to-end control, as platform-level Unmanned Aerial Vehicle (UAV) movement and end-effector-level arm manipulation differ substantially in action scale, dynamics, and control objectives. In this paper, we propose AIR-VL...
