The Earth mining mech is equipped with a laser-cutter on the left arm, and an articulated manipulator on the right arm. After cutting chunks of space-rock, it deposits them into zero-g mining carts for transport. The carts can be attached to the rear of the mech and linked together in a train. Both the feet of the mech and the bottom of the carts have anchor piles to hold them in place when working. The "head" unit can fold flat against the back (like a cape) for easier storage and transport.
The machine is designed to operate in a zero-g environment and is a mining/worker-type robot.
The Mars Military Mech shares a similar frame to the Earth Military Mech, with added Martian technology. It mounts a variety of sensor pods and gear, and each arm can be equipped with punching blades for close combat.
This continues the tradition of "no human hands." The blade unit slides onto the forearm and then the grey clamps at the end of the arm grab onto the back of the blade.
