N2 - Reliable collision detection is critical for high-speed operation of dual-arm Selective Compliance Assembly Robot Arm (SCARA) robots. This paper presents a collision detection framework based on a generalized-momentum extended state observer (ESO) with parameter uncertainty compensation. First, a dynamic model of a dual-arm SCARA robot is established under belt-driven geometric constraints. Then, considering inertial parameter uncertainty, a momentum-based ESO with parameter uncertainty compensation is developed to estimate external joint torques without inertia matrix inversion or jointacceleration measurements. Simulation studies involving rigid and compliant contact scenarios demonstrate that the proposed method achieves reliable and timely collision detection with lower usable thresholds in the presence of parameter uncertainty.
