Project Objective

To design and build a line-following robot with a variable-distance catapult launcher and rack-and-pinion steering as the final project for a robotics design class.

What Was Done

Collaborated with a team of four to design and fabricate a robot capable of following randomized line paths and launching projectiles with adjustable range. The frame components were laser-cut from acrylic and Delrin plastic. The drive system and rack-and-pinion steering were designed in SOLIDWORKS and Fusion 360, then 3D printed. Developed line-following algorithms using Arduino software and PID controllers for precise target tracking. Participated in a university robot design challenge, achieving first place for Best Design.

Skills Used

• Team collaboration and project management

• CAD modeling and design (SOLIDWORKS, Fusion 360)

• Fabrication techniques (laser cutting and 3D printing)

• Arduino programming (sensor integration, motor control, PID algorithms)

• Mechanical engineering (rack-and-pinion steering)

End Result

Delivered a high-performing robot that won first place for Best Design at the university robot design challenge. The project demonstrated excellence in design, fabrication, and programming, meeting all performance criteria effectively.
