The Cal Poly Mechanical Control Systems Laboratory currently employs an outdated device, known as the Motomatic, to teach students about various motor characteristics and control methods. These include open-loop vs. closed-loop control, speed vs. position control, and DC motor response curves. The current device does not function properly and produces unreliable data due to overwhelming non-linear effects such as stiction and shaft misalignment. Our team was tasked with designing a replacement device that retains many of the same educational goals as the original lab procedure, while also adding new educational goals pertaining to the device system dynamics. The new apparatus, dubbed the Dyno-Mite is a one tenth scale tire testing machine, incorporating two DC brushed motors, adjustable mechanisms, and load cell measuring devices. The design will also pay special attention to modularity so that future adjustments and modifications can be made to the lab apparatus, allowing for instructors to tailor the machine to meet their specific educational goals.
