Elevating and Scoring Mechanism Design for Mobile Robots

Presented at Advancements in Sustainable Manufacturing Practices

The VEX Robotics 2023-2024 game “Over Under” is a game where two teams of two robots each compete to score points within a 2-minute time limit. Robots must be able to score points both autonomously and with input from their drivers. Points can be scored by moving Reuleaux triangles, similar to rounded pyramids, under goals and elevating their robots off of the ground using a vertical pole, called the elevation bar. The objective of this project is to design and build an offensive robot that will be able to score a high number of points as efficiently as possible. This will be done by creating a well-rounded robot that can move and score Reuleaux triangles, referred to as triballs, as well as elevate off the ground at the end of the match. The robot will also be compact and lightweight, so it can easily navigate the field. It must also be able to withstand minor collisions with other robots and the elements on the game field. The robot will feature an intake to move triballs, wings to push multiple triballs at a time, and a lifting arm with a claw to grab onto the elevation bar and lift off the ground. Most of the construction of the robot will be done using standard VEX parts, 3D-printed polylactic acid (PLA) parts, and milled aluminum and Delrin parts.
