Overview
The Multipurpose Mobile Manipulator MkII, nicknamed the Megamark, is the upgraded successor to the MMM MkI. It’s bigger, better, and stronger — now featuring an all-metal aluminum body for improved durability and payload capacity, plus a host of new features.
Key Features

- Two 12V 7AH SLA batteries — 6–8 hours of runtime under normal load, with battery life indicator
- Arduino Mega 2560 — connects to the robot’s laptop-for-a-face via USB
- Modular 3D-printed grippers — swap end effectors for different tasks (coffee delivery, plant watering, door opening, and more)
- Plenty of mounting holes — easily add custom sensors and electronics
- 0.5kg payload capacity per arm
