Robotics Day at Sac State 2025




The first annual Robotics Day at Sac State took place on March 21st 2025! I proposed this outreach project to the Competitive Robotics Club back in late 2023 and have been working on planning this event since then. I wanted to provide an opportunity for students to explore engineering and show them a fun side of engineering. I wanted them to see the really amazing things they could do with engineering rather than the challenges that come along with engineering that discourages many students from following this path.
My goal from the start was to make this event completely free for students and remove that financial barrier that comes along with many robotics and engineering-related activities and I am so proud to say that we were able to accomplish this goal and allow students from any financial background an opportunity to build and compete within robotics.
In addition to providing a way for kids to do engineering, we also displayed work from our passions within engineering to bring the arenas to life. I programmed four Raspberry Pi Picos to put on different light and motor shows for the kids as they go through the maze and all of the boards and wiring was attached to the maze in a way that the kids could see the engineering work and ask questions about what it all did. Another member of my team designed and 3D printed different parts of a dragon to attach to servo motors. We were able to make these arenas very interactive and a super fun experience for the kids navigating them!
I had so much fun putting on this event and seeing these students get so excited about robotics and engineering and I can't wait to put this event on again next year and watch this program continue after I graduate!
















































The students participating in this event were first taught how the different motors and connectors worked and the basics of how to build the starting structure of their robot. After that, we randomly assigned the students different groups and my team floated between the tables helping them to build their robots or execute the different ideas they had as they were building. They needed to design a robot to take on three different courses. They had to navigate their robot through a maze, compete in a game of soccer with 150 ping pong balls, and compete in a brief battle-bot battle. They had to make a robot that could not only survive these arenas, but they also had to build it in a way for there to be multiple drivers at the same time. They were required to have one team member operating the two driving wheels and another team member operating any weapons they build or moving parts. Each group needed to work together and communicate with people they had never met before to succeed in the different courses.
















































Here are some pictures of the design process for the arenas and Lego robotics kits. We constructed and painted all of the arenas by hand in a way where they can be easily disassembled and stored in our club room. We have camera mounts for each of the arenas allowing us to have a live video feed of the arenas on the big screens in the room for kids and parents who couldn't see the arenas to check out and watch. I programmed two of the arenas and equipped them with sensors and lights. In the arena where the kids would be playing a game of soccer, there was one Raspberry Pi which took input from some force sensors and lit up the lights around the center of the arena whenever a robot hit that block. The maze was the most computer-engineering heavy part of the project. This arena has 3 Raspberry Pis on it that control a variety of sensors, servo motors, and lights to bring different parts of the arenas to life as the robots pass through those parts. As the robot goes over the bridge, the bridge will light up and the servo motors controlling the dragon will begin to move. When the robot starts going under the dragon tunnels, the path will light up green and the bridge lights and motors will turn off, and finally if the robot hits any of the pegs they must avoid in the last stretch, the pegs will flash red. We also hosted a few different trial runs open to any Sac State student to test out or Lego kits and make sure we were prepared for the event!
