Space Robotics for On-Orbit Servicing
Research Guide
What is Space Robotics for On-Orbit Servicing?
Space Robotics for On-Orbit Servicing develops manipulator arms, dexterous hands, and control algorithms for satellite refueling, repair, and assembly in orbit.
This field covers visual servoing, force-torque control, and dual-arm coordination for cooperative and uncooperative targets. Key missions include ETS-VII with a 2-m six-DOF arm (Yoshida, 2003, 263 citations) and Orbital Express for autonomous rendezvous (Friend, 2008, 202 citations). Over 20 reviews and experiments span 2003-2021, with Flores-Abad et al. (2014) cited 1235 times.
Why It Matters
On-orbit servicing extends satellite lifespans by refueling and repairing, reducing launch costs for space infrastructure. ETS-VII demonstrated robot dynamics in orbit (Yoshida, 2003), while Orbital Express proved autonomous capture (Friend, 2008). DLR technologies enabled servicing hardware (Hirzinger et al., 2004), supporting debris removal and assembly missions amid LEO congestion (Boley and Byers, 2021).
Key Research Challenges
Uncooperative Target Pose Estimation
Determining pose of tumbling satellites without markers requires vision-based methods. Opromolla et al. (2017, 296 citations) review techniques for close-proximity operations. Accuracy degrades with lighting and relative motion.
Contact Dynamics and Force Control
Manipulators must handle uncertain contact forces during capture. Flores-Abad et al. (2014, 1235 citations) detail compliance control needs. Microgravity complicates stability (Yoshida, 2003).
Dual-Arm Coordination in Orbit
Synchronizing arms on chaser satellites demands real-time planning. Papadopoulos et al. (2021, 173 citations) survey capture strategies. Disturbance from motion affects precision (Li et al., 2019).
