Kinematics and Direct Torque Sensing in xMate CR Collaborative Robots

Engineered by Beijing Rokae Technology Co., Ltd. (ROKAE), the xMate CR series of flexible collaborative robots establishes a milestone in safe cage-free human-robot collaboration across demanding manufacturing cells.

In conventional cobot designs, collision detection relies heavily on monitoring motor phase currents. Due to internal gearhead friction and arm link inertia, current-based estimation suffers from delayed reaction intervals and reduced sensitivity thresholds.

ROKAE engineers solved this limitation by embedding dedicated high-resolution joint torque sensors inside every rotary articulation (full-joint torque sensing architecture).

Each of the 6 or 7 rotary joints on xMate CR manipulators is continuously sampled by the servo controller within 1 millisecond.

This enables instantaneous contact sensing down to 0.5 N and smooth deceleration profiles, entirely preventing impact damage and satisfying ISO 10218-1 and ISO 13849-1 (PL e, Cat 4) standards.

Benefiting from a 7-axis kinematic topology on redundant models, xMate CR robots possess kinematic redundancy.

This allows the arm to circumvent physical workspace obstacles, reposition its elbow while maintaining fixed tool center point (TCP) orientation, and perform complex electronic assembly, optical inspection, and medical rehabilitation tasks with high mechanical compliance.

OptiMotion Dynamic Path Planning and TrueMotion Active Vibration Suppression

The algorithmic core of ROKAE robotic systems resides within the Titan motion control architecture and xCore cabinet platform, powered by an industrial hard real-time operating system.

The proprietary OptiMotion algorithm models dynamic multi-axis interaction torques in real time, accounting for actual payload weight and moment of inertia.

Rather than imposing arbitrary static acceleration caps, OptiMotion computes dynamic motor capacity along every trajectory segment, maximizing velocity on linear stretches and adjusting deceleration ahead of tight bends.

This shortens manufacturing cycle times by 20% to 30% without over-torquing reduction gearsets.

To prevent micro-vibrations during high-speed contouring, the TrueMotion algorithm applies active resonance compensation. By evaluating structural compliance throughout arm linkages, TrueMotion generates high-frequency anti-phase compensating commands across servo axes.

This guarantees precise path tracking during rapid dispensing, laser cutting, and robotic arc welding on delicate thin-gauge sheet metals.

Industrial Articulated Arms: XB Precision Series and NB Heavy-Duty Lines

ROKAE industrial articulated robotic portfolio caters to divergent automation requirements, bifurcated into agile compact XB robots and robust medium-to-heavy NB articulated manipulators.
