P08201 – 10kg Robotic Platform This project is supported by a gift from the Gleason Foundation to the mechanical engineering department at RIT..

R I T Project Description The mission of this family of projects, within the Vehicle Systems Technology Track, is to develop a land-based, scalable, modular open architecture, open source, fully instrumented remote/controlled vehicular platform for use in a variety of education, research & development, and outreach applications within and beyond the RIT KGCOE. This student team will re-design two modular, robotic platforms capable of carrying a payload anywhere in the robotics lab, room # in Building #09 on the RIT campus. One drive platform configuration shall be three wheeled, with at least one motor module, and a payload capacity of at least 2.5kg. The second drive platform shall have at least four wheels, with at least two motor modules, and a payload capacity of 10kg. The second platform will be required to accomplish two tests as stated in the PRP.

R I T Customer Needs The platform must re-use as many parts from previous designs as possible. The platform must perform safely The platform must be able to carry a payload of 10kg The platform must fit within the $8000 Budget split between all 3 project groups. The platform must be battery powered The platform must be robust The platform must utilize off the Shelf Components The platform must perform all testing requirements successfully The platform must be impressive for high school students in the US FIRST robotics competition. The platform must use interchangeable modules that can be swapped within 120 seconds. The platform must be able to be scaled up or down in size and payload capacity. The platform must be open source to allow for other senior design projects on it. The platform must be able to be controlled remotely
