Notable capabilities (2)
- Embodied reasoning in the public Gemini API: ER 1.5 (2025-09-25) exposed embodied reasoning (pointing, 2D boxes, trajectories, task planning, tool calls) available in the public Gemini API, while the VLA stayed partner-only. source
- Instrument reading (ER 1.6): Reads pressure gauges, thermometers, sight glasses and digital readouts: 86% (93% with agentic vision) vs 23% for ER 1.5 and 67% for Gemini 3 Flash; built with Boston Dynamics and used by Spot for inspections. source
Earlier embodied-reasoning previews; use Gemini Robotics ER 2 instead.
Changelog: 2026-09-29 added ER 1.6 instrument-reading capability and linked the new entry 2026-04-14-gemini-robotics-er-1-6.
