TactileStep Makes Humanoid Landings Softer

TactileStep makes a strong case that vision alone is insufficient for reliable humanoid locomotion: seeing a foothold is different from knowing how the foot actually loaded it. The results are promising, but the system remains a research prototype with hardware, sensing-bandwidth, and energy tradeoffs.

• –Compact tactile features let the policy close the loop on real contact without processing the full pressure map.
• –Reported gains include up to 30.1 dB lower impact noise and broader, more centered support across tested terrains.
• –The approach was validated on a real Unitree G1, strengthening its sim-to-real credibility.
• –Simulated policies generally used more energy and moved slightly slower than the vision-based baseline.
• –Code, weights, long-term sensor testing, and deformable-terrain evaluations were not yet available. [Independent technical review](https://roboskin.ai/news/tactilestep-sole-pressure-humanoid-locomotion)
