This is the final CAD design of the sumo bot.
The colors in the image denotes the following manufacturing technique
Black= Laser Cut 1/4" Acrylic
Blue = FDM 3D printed PLA
The acrylic-to-acrylic connections are dove-tailed and adhered together. The 3D printed parts have bolted connection.
To the left is an cross-sectional view of the spindle and the actuator motor. When the actuation is triggered, the motor rotates the spindle which unravels or pulls strings that are attached to the wedge arms lowering or raising them.
The boundary of the sumo bot arena is lined with black tape. By using infrared sensors the sumo bot can detect this boundary and alter its course.
For the Category 5 Sumo Bot, an single IR sensor is located at the bottom of the chassis, but also inside each of its acrylic wedges. Increasing its range of detection.
