"Touch Dreaming" Gives Humanoid Robots 90.9% Better Dexterity — CMU & Bosch Paper

The Research

Researchers from Carnegie Mellon University and the Bosch Center for AI have developed a humanoid robot control system that "dreams" — predicts — upcoming tactile signals rather than merely reacting to them. The Humanoid Transformer with Touch Dreaming (HTD) achieved a 90.9% improvement in average success rate over the stronger vision-only baseline across five dexterous real-world tasks.

How It Works

HTD combines imitation learning with prediction of future contact-related signals. Instead of reacting to current tactile feedback, the robot anticipates how touch and force will evolve moments ahead and coordinates movement accordingly. The architecture integrates whole-body reinforcement learning, upper-body inverse kinematics, and dexterous hand retargeting.

Tasks Tested

T-shape part insertion

Book organization

Towel folding

Cat litter scooping

Tea serving

Why It Matters

Contact-rich dexterous manipulation remains one of the hardest open problems in humanoid robotics. HTD's open-source release means other researchers and robot manufacturers can immediately test the approach. If the gains transfer to commercial platforms, the work accelerates deployment in manufacturing, logistics, and domestic service.
