Close call. GR-2 and M1 trade wins across the matrix.
Readiness, uptime, navigation & connectivity
Price accessibility and ROI clarity
Payload, speed, runtime & labor replacement
Environment fit, footprint & long-term upside
Embodied AI research on grasping, force feedback, and sim-to-real transfer
Heavy parts assembly in automotive or appliance manufacturing where human-scale bipedal access to elevated worktables is required
If immediate deployment is the priority, choose GR-2. If the goal is to be ready when M1's capabilities mature, track it.
