Design Requirements

In addition to achieving the required tasks to complete a full game round, the robot must also:

• Automatically determine which side of the arena it's on

• Electro-mechanically indicate the side of the arena at the beginning of a game

• Provide an indication of when a game round in progress that deactivates once time expires

• Fit within a 320 mm by 320 mm cube at the beginning, and may expand up to 480 mm by 480 mm in length and width and 570 mm in height after the game starts

• Contain at least one PIC32 SPI leader and one PIC32 SPI follower device

• Fall within a total budget of $200 per team

Core Features

Game Strategy

PIC Destroyer begins by rotating out of the starting corner, using signals from the IR sensor and limit switches that detect the walls until the beacon is located. If Beacon L is detected, the robot identifies that it is on the green field and rotates the flag-indicating servo in one direction; if Beacon R is detected, the flag servo rotates in the opposite direction.

The robot then turns toward the line leading to the coal dispenser and follows the line to reach it. At the dispenser, PIC Destroyer collects six pieces of coal using the grabber arm and deposits them into the robot’s bucket, dropping three pieces on each side. It then follows the line to the nearest game bucket and pulls it down using the lever arm. Once the game bucket is lowered as close to the ground as possible, PIC Destroyer positions its own bucket directly above it and releases half of the collected coal by rotating the bucket floor.

Next, PIC Destroyer follows the line to the middle bucket and repeats the process, dispensing the remaining coal. Finally, it follows the lines to the furthest bucket from the dispenser and pulls it to the ground using its lever arm, allowing the PIC Destroyer to win 3 buckets in the allotted game time.
