The design for the 2015-16 season built off of our successful design in the 2014-15 year. We went, again, with a skid-steer front load bucket design, but made significant changes to reduce ballast need. The changes include longer treads, an integrated hollow chassis, and a sliding arm mechanism to keep the center of mass as close to the center of the robot as possible.

The design of the robot considers the unit operations of mining for determining the most effective methods of loading, hauling, and dumping the material. The robot used a bucket conveyor to load the material. The bucket volume allows for approximately 33 kilos of material to be loaded over three trips across the field. The drive train will be a tread system. Gear and motor selections provide ample power and speed to traverse the course and mine material. This design represents the most effective and simplest solution based on the constraints imposed by the competition.

Control and Communication
Electrical and control systems are designed for efficient data and energy use during the competition, as well as to facilitate implementation of autonomous functioning.
The electronic components are currently controlled remotely by computer input, via a computer program custom made in Java to control and monitor all aspects of the robot.
