Below are some sketches and images showing the evolution of our robot from an incredibly simple trapezoidal form, to its final shape. These images include CAD sketches of the base and three-tier main body. The keen observer will also notice that we replaced our first attempt at a base, as we made improvements to the design to allow for easier access to the motors and stronger mounting points for the line sensors. We hope this series of images will encourage you to start sketching and designing, even on the back of an envelope, because you can quite quickly move from a sketch to a full prototype that you can hold!
