Rover Mechanical Design
The Rover design includes several innovative
mechanical designs including:
Low Temperature Actuators
Custom actuators were designed from commercial components so they could function at -80C. These components include:
- Maxon DC motors
- Globe Planetary gearboxes
- Castrol Bray Lubricant
Lightweight Aluminum Structures
Intricate structural designs created by involving machinists in design process:
- "T-slot" hollowing
- NC machining
- Integrated Bearings
Kinematic Lander Supports
The Rover is held against the Pathfinder Lander with three stainless steel cables. Upon arrival at Mars, pyrotechnic devices will cut the cables, freeing the Rover.
