PROJECT TOPICResearch Frontiers & Advanced Kinematics
Deployable Scissor Truss Boom
A deployable structures mechatronics concept studying kinematic pantograph scissor linkages, synchronized lead-screw drives, and over-center locking hinges to deploy long rigid booms from ultra-compact canisters.
High-Expansion Deployable Kinematic Structures
- ✓Expands over 15x its stowed length from a compact transport box in under 30 seconds.
- ✓Maintains high bending stiffness using triangulated cross-braced scissor members.
- ✓Features over-center mechanical locks to remain fully rigid without continuous motor power.
The Engineering Challenge
Problem / Objective
Long inspection booms and camera masts cannot be transported on small mobile rovers without massive vehicle overhang.

Engineering Considerations & Edge Cases
- Cumulative joint pin play causing drooping and sway at full 8-meter extension
- Jamming if scissor links deflect under asymmetric lateral wind loads
Applications
