// Actually, I don't think this is true --> For Raziel's rover deployment, a sabot assembly was initially developed, but ultimately did not make it into flight hardware. Included here are lessons learned during the making of the sabot.
// Please update this page as you wish, payload person or non payload person!
Components
A sabot is used to enclose a payload for launch, and - in Raziel - consists of two main sub-assemblies: the foam sabot shell and the inner metal enclosure.
Sabot shell halves in closed configuration. Rover enclosure in open configuration.
The square enclosure fits into the sabot shell to create a housing, further modifiable to be robust enough to withstand a rough landing.
The flight competition required the enclosure be made to resemble a Cube-Sat of designation 2U.
Deployment Mechanism
Upon landing, the sabot is able to automatically deploy its rover.
Torsion spring hinges were installed along one edge of the enclosure connecting its two halves, allowing the energy in the springs to be stored while the sabot is in closed configuration. To remain in closed configuration, the sabot assembly was held together by one loop of (dimension) rope, tied around.
Deployment is achieved when a team-built PRC (Pyrotechnic Rope Cutter) installed by the loop of rope activates and cuts the rope, releasing the energy in the torsion spring hinges and allowing the sabot halves to separate.
See the sabot assembly in its open configuration below:

Materials and Preparation
Stiff foam was used to fabricate the sabot shell in the aim of absorbing impact upon landing.
