Precision Motion Capture & Dynamic Ground Truth for Humanoid Robotics

Bridging Biological Motion and Multi-DoF Robotic Actuation

Humanoid robots operate with dozens of highly articulated degrees of freedom (DoFs) subject to unstable inverted pendulum dynamics. Onboard joint encoders, foot force sensors, and embedded IMUs suffer from accumulative state estimation drift and dynamic contact shocks.

To synthesize stable bipedal gaits, train neural motor policies, or benchmark push-recovery controllers, engineering teams require an external reference frame. Tracklab’s humanoid robotics mocap platforms deliver sub-millimeter positional ground truth and drift-free angular kinematics, enabling you to isolate algorithmic control errors from physical structural compliance.

Sub-Millimeter End-Effector & Pelvis Tracking (< 0.1 mm)

Accurately measure 6DoF center-of-mass (CoM) drift, pelvis tilt, and swing-foot ground clearance.

High-Rate Joint Angular Velocity Capture (Up to 360+ Hz)

Track high-speed impact transients during foot-strike transitions without motion blur.

Synchronized Kinetic & Kinematic Data Streams

Integrate optical 6DoF markers, IMU attitude, and Bertec/AMTI force plates into a single synchronised clock domain.

Specialised Motion Capture Applications for Bipedal Systems

Swing-Foot Ground Clearance Tracking.

Measure sub-millimeter clearances during swing phases to prevent dynamic trip events on uneven surfaces.

Center of Mass (CoM) & Pelvis State Estimation

Provide independent 6DoF telemetry of the pelvis and trunk to benchmark Kalman-filtered state estimators.

Ground Reaction Force Integration

Synchronise optical foot marker tracking with multi-axis force plates to calculate exact Center of Pressure (CoP) and joint torques.
