Arachnoid robotic shells are 1-meter in length, segmented into two parts, with a smaller head like a spider or termite. They feature four pairs of 1.5-meter-long retractable arms/ legs, capable of rotating around the axis of the body, with built-in pneumatic systems for propelling the bot with small leaps. The manipulator claws on each arm/leg can be switched out with extendable mini-wheels for high-speed skating movement. A smaller pair of manip- ulator arms near the head allows for closer handling and tool use. In zero-g environments, arachnoids can retract their arms/legs and maneuver with vectored air thrusters.
