As a team, our Robot design will have two modes. One having remote control, and the other having autonomous guarding capabilities with soft weapon activation on close proximity.

Our weapon of choice is to have a spinning blade with the option for interchangable weapons (pending due to safety restrictions).  The 'soft' weapon option would be a confetti  or cotton ball cannon (lol)

For robot movement, we have decided to use 2 motors (at the rear) and 2 dolly castor wheels (front). 

We have decided to salvage parts, aluminium extrusion profile and fasteners from our old project 'farmbot' to cut costs on materials.
