Pivoting 2-Stage Cascading Telescopic Arm
The purpose of this project was to design a cascading arm that can operate in a plane of motion rather than an axis.
- Two-stage cascading arm driven by chain with option for third stage allows for extended reach with a compact stowed position
- 120:1 reduction to drive pivot - calculated using motor current charts
- 6.5:1 reduction to drive extension - calculated using gear ratio and chain reduction
- Three Kraken x60 motors minimizes brownout currents and avoids overheating
