Early model concepts

Based off initial sketches I began modelling and texturing roller concepts. At this stage it was all about finding the most efficient way to model the roller and it's various components. This would speed up my workflow once I began modelling final models.

This model lacks some of the key features of the roller. The cap that allows the operator to pour in the insecticide, the hand pump to pressurise the tank and the spray gun and hose. Also At this stage I do not know where I will place the hose.
I received some feedback on this model regarding the treads. They were too thin and would have trouble gripping a tarmac or dirt road.On future iterations I will focus on increasing the grip of the roller.

On this tank model I increased the treads so they covered the entire area of the container.
Still this type of treads would have trouble gripping the grounds as the treads lacked any teeth.
Also because the treads covered the whole area of the tank there is no room to place the window, which allows the user to check how much liquid is in the tank. I still want to include this feature so I will have to reconfigure the treads.
