After updating the robot’s chassis to correct existing issues – and to accommodate additional components – the body of the robot was also redesigned.

The new form allows for complete separation between all “skeletal” components of the robot, and the outside container. What this means is that the body can be easily removed and replaced without altering the position of the ultrasonic sensor or IR sensors/lights.

Additionally, this model includes divets for 5-6 solar panels to be attached, as we move forward with implementing solar energy for powering & charging the Sunbots. For now, the panels are situated at a 40 deg angle on the robot’s exterior – though we are about to start experiment with adjustable solar panels to account for differences in sunlight.

Like the previous prototype, this one was also fabricated with sliced forms of cardboard:

While the slice-forms offer no place to attach the solar panels with screws/etc. – the panels fit snugly within the divets. In the future – with a solid prototype – we will need to find a way to secure the solar panels while keeping their wires accessible.
