The problem Automatic s&c robot solves

Automatic collects waste from the garden and time to time sprinkles water in the garden

Challenges we ran into

During designing the robot, creating outer contour was difficult. After exploring various options available, we decided to design it with surface modelling, giving us a great grip over design.
During, designing number of parts are to be adjusted within limited space available, hence optimization was issue.
As space was limited, space for setting up a turning mechanism for wheels was difficult, hence we came up with idea of using omni-directional spherical wheels.
