Robot base

Right from the start, I wanted to try something different than everyone else, so instead of going with the standard robot base design, where the motors and wheels were simply mounted on a single, flat piece of wood or plastic, I split my base into two parts connected by PVC pipes. This allowed for the two ends to rotate when coming across rough terrain, and for the front to crush in if I were to ram my robot into a wall. The latter feature plays a crucial part in my main strategy.

Strategy

Since we're limited to 4 motors, and 2 are likely used to provide the drive, we can only power our scoring components using the remaining 2 motors. However, I decided it was entirely possible for me to work around that with my extendable robot base. By ramming my robot into a wall, it essentially moved the back of my robot forward just through the drive wheels. If I were to mount a claw on the back end of the robot, I could spare a motor that would otherwise be used to extend the afore-mentioned claw.

Hence, my strategy involves going after the 1st four noodles in the noodle forest, scoring with the 5 balls that I would be allowed to put on my robot beforehand, and then driving my robot into the river at the conclusion of the rounds while carrying the extracted noodles. Since this takes advantage of 3 separate scoring components, it actually allowed me to score a maximum of 546 points without even using either of the 2 remaining motors.

MCM (Most Critical Module)

My most critical module was a spring-loaded claw of sorts that mounted onto the back of my robot. As I crashed my robot into the edge of the noodle forest, the back of my robot would move forwards and squeeze the noodles into my claws. Due to spring-loaded doors, my claw then essentially locks the noodles in place, and I can just back out to extract the noodles

Secondary Modules

To deliver the 5 food balls into the starting box, I created a ball carrier with a spring-loaded door that would open once I rammed my robot into the side of the starting box. The door has an extension that hits on the outer edge of a scoring hole on the side of the box. This then allows the food balls to fall down by gravity.

To make use of one of my extra motors, I also mounted an arm on top to reach up and snag onto the food ball door. Once the arm catches on to the door, I would just drive foward with my robot and pull the door open, then scoot back to push the fallen balls into the starting box.

I also put in a motorized shovel arm that would be used to push river balls from the river onto my opponent's side. as a defensive maneuver.
