// 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.

Structure

A sabot is used to enclose a payload for launch, and - in Raziel - consists of two main sub-assemblies: the foamboard sabot shell and the inner metal enclosure.

...

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 aroundplaced within a notch cut into the sabot shell.

Deployment is achieved when a team-built PRC (Pyrotechnic Rope Cutter) installed onto the loop of rope activates and cuts the rope, releasing the energy in the torsion spring hinges and allowing the sabot halves to separate.

Lesson #1: To inhibit rotational freedom on a bar fastened down at both ends, consider adding extra bolts (one would probably suffice) to block the motion of the bar in the desired direction.

Lesson #2: Make doubly sure that the materials you plan to order (be it from McMaster-Carr or another vendor) are the ones you require. If you are not sure, do not hesitate to contact your vendor.

Lesson #3: Never give up.
