Tactile Simulation Learns Shear Without a Soft Body
TactileLab derives dense tangential flow from rigid-body contact, then translates real sensor images back into the simulated representation.
Summary
TactileLab derives dense tangential flow from rigid-body contact, then translates real sensor images back into the simulated representation.
The framework pairs simulated tactile flow with a contact-depth field and a policy architecture for long proprioceptive and tactile histories. It scales reinforcement learning without the cost of deformable-body simulation, then maps heterogeneous real tactile streams into the learned flow-and-depth representation. The authors demonstrate dual-arm and in-hand manipulation deployments. These demonstrations support the pipeline on tested sensors and tasks, not universal sim-to-real transfer.
