Martian is a one-arm cleaning robot designed for the Stanford Research Center that reaches high and low to clean showers, tubs, sinks, floors, and countertops. Unique tool ends, or “hands,” can be swapped out for specific cleaning needs. Cleaning fluids are stored on its base for easy robot arm access. Three omni wheels that can turn sideways let Martian maneuver within tiny spaces. Its slender form helps with camera and LIDAR positioning requirements. We gave Martian a sleek utilitarian look considering its purpose, while also giving it a personality like an at-your-service butler.
