Bumblebee 2.0 Mechanical

The 2013-2014 vehicle, BumbleBee 2.0, features a complete redesign from the previous vehicle. This design improvement, inspired by industrial ROVs (Remote Operated Vehicles), has reduced the overall weight to 48 kg while allowing more sensors and actuators. At the same time, this increases robustness and modularity to aid disassembly during troubleshooting. The key features of the mechanical system are the frame, the hull, the manipulators and the external housings. Custom battery pods have been built to accommodate the newer and larger battery management system.

All aluminum components of the mechanical subsystem are fabricated from 6061-T6 aluminum. They are then hard anodized and sealed for maximum corrosion resistance, electrical insulation and scratch resistance. FEA (Finite Element Analysis) is employed for weight optimisation.
