Challenge: Develop an autonomous system with two collaborating robots capable of picking, sorting, and delivering balls of different colors under time constraints and unpredictable task conditions.
Solution: The project resulted in a two-robot system where the first robot autonomously picked up unsorted balls and delivered them to the second robot. The second robot then sorted the balls by size and stored them in separate compartments on its platform. After sorting, it transported the balls to the correct bins on the field based on their color. The mechanical design emphasized lightweight materials and modular 3D-printed components, while the software enabled autonomous navigation and coordinated task execution between the two robots.
Impact: The system showcases how multiple autonomous robots can collaborate to complete complex tasks with minimal human involvement. The approach is scalable and applicable to areas such as warehouse automation, recycling processes, and manufacturing lines that require flexible and adaptive sorting solutions.
Prototypes: Throughout the development process, multiple prototypes were built to test and refine key components. Early versions focused on a basic chassis with drive functionality, while later iterations included the full mechanical design and sorting system. Extensive sketching and planning were carried out to ensure optimal layout and functionality. Many parts of the robots were constructed using masonite, a material well-suited for rapid and cost-effective prototyping with a laser cutter. This allowed for quick testing and iteration of ideas. Additionally, 3D-printed components were used with varied infill settings to balance strength and weight. Through hands-on testing, the team identified the importance of robust error handling and precise component tolerances for reliable performance.
