Simulation and real-world dexterous manipulation demos

The video shows the high-DoF dexterous hand operating in IsaacSim and on the real bimanual robot platform. It highlights egocentric tracking, retargeting, and tactile residual control across contact-rich tasks, with the simulation segment illustrating controlled behavior under repeatable conditions and the hardware segment showing the same pipeline deployed on the physical system.

Overview

Abstract

Fine-grained, bimanual dexterous manipulation remains a foundational challenge in robotics. Traditional teleoperation systems often fail in contact-rich tasks because embodiment gaps hinder accurate kinematic mapping, while tactile and force feedback remain absent. DexTeleop-0 introduces a tactile-driven adaptation strategy that translates coarse human tracking intents into precise, force-compliant robotic commands with tactile sensing.

By estimating contact points and leveraging a tactile-enabled fingertip force-sensing profile, the system dynamically computes localized corrections using operational space Jacobians. Across simulation and real-world hardware, DexTeleop-0 improves task success rates and execution efficiency in robust grasping, disturbance-resilient manipulation, and complex dexterous tasks.

Sim and Real Validation

DexTeleop-0 system architecture with egocentric perception, retargeting, tactile force balance, and robot execution.
DexTeleop-0 turns egocentric tracking into force-aware robot actions through real-time tactile residual optimization.

Core Intuition

Force balancing corrects unstable contact before it becomes failure.

Vision-only teleoperation captures human intent, but it cannot directly sense pressure, slip, or local force imbalance. DexTeleop-0 keeps the operator's command as the nominal trajectory while adding small tactile residual corrections that restore stable contact geometry.

Before and after tactile balancing showing unstable and stable contact forces.
Before balancing, asymmetric fingertip forces destabilize the interaction. After balancing, tactile feedback reshapes the hand posture into a stable force-balanced configuration.

Method

From egocentric tracking to force-compliant execution

Ego-centric perception

A Meta Quest 3 headset captures human hand joints and wrist poses without external motion capture. Human hand states are represented as transformations \(\mathcal{H} = \{\mathbf{T}_1,\dots,\mathbf{T}_M\}, \mathbf{T}_i \in SE(3)\), while wrist motion provides \(\mathbf{T}_w \in SE(3)\).

Dexterous hand and arm retargeting

Arm IK maps wrist pose to \( \mathbf{q}_a \), while vector-based hand retargeting maps 26 tracked human hand joints to a 22-DoF dexterous hand. A robust Huber objective and temporal regularization suppress tracking outliers and jitter.

Contact state estimation

For each active fingertip, tactile sensing estimates contact force \( \mathbf{f}_i^w \) and contact point \( \mathbf{p}_i^w \). A logistic hysteresis weight \(w_i \in [0,1]\) smooths transitions between release, uncertain contact, and reliable contact.

Force-balanced residual action

The executed command is \( \mathbf{q}_{final}=\mathbf{q}_{tele}+\Delta\mathbf{q} \). A box-constrained QP solves residual joint updates at 30 Hz, combining local fingertip force tracking with object-level force-torque balance.

Unified residual objective
\[ \min_{\Delta \mathbf{q}} \frac{1}{2}\Delta \mathbf{q}^{\top}\mathbf{H}_0\Delta \mathbf{q} + \mathbf{g}_0^{\top}\Delta \mathbf{q} + \lambda_F \|\mathbf{A}_F\Delta \mathbf{q}+\boldsymbol{\rho}_F\|^2 + \lambda_{tb}\|\mathbf{A}_{\tau}\Delta \mathbf{q}+\boldsymbol{\rho}_{\tau}\|^2 \]

A · Sim-to-Real Alignment

A matched digital twin and physical robot, accessible and consistent

DexTeleop-0 is evaluated in both NVIDIA IsaacSim and on a physical bimanual dexterous platform. Each branch pairs a 6-DoF UR7e arm with a 22-DoF Sharpa Wave dexterous hand, producing a 56-DoF control problem driven by egocentric Meta Quest 3 tracking. The aligned setup lets the same teleoperated trajectories be replayed under controlled physical variation before deployment on hardware.
