Motivation
- Mobile robots are of highest interest for unmanned planetary exploration
- The European Space Agency (ESA) is seeking for innovative micro-rovers for future missions to mars, moon and other planets
- Human guided mobile robots have a high potential also for various applications on earth

System Requirements
- Stowed dimensions (cm): 30 x 20 x 20
- Mass of the System: 2 Kg (robot) + 2 Kg (payload)
- Electrical power provided by lander: 2 Watt average
- Maximum obstacle height to overcome: 10 cm
- Possibility to precisely position the on board sensors
- Maximum speed: 5 m/h
Proposed solution: SpaceCat, The “Stepping Triple Wheels” Robot
- Rolling capabilities with the three wheels arrabged in a triangle on each side
- Walking capabilities with the two wheel frames
- The center of gravity of the rover can be adjusted with some sort of robot arm >>> facility to climb on obstacles and to recover after flipping over
- All the scientific instruments are arranged within the payload frame which can be rotated to allow precise positionning of the instruments
