To check out parts from the R@B Parts Library, fill out the application below to get approval from the R@B officers. Once you gain approval, an officer will contact you and coordinate a pick-up time for your parts. Parts can be borrowed until the end of the semester.


If you would like to borrow more than $100 worth of parts, we ask you in the application to provide us information about our project and require that you allow us to list your project on our website as a Robotics@Berkeley affiliated project.

The Robotics@Berkeley Parts Library is a collection of hardware components commonly used in robotics projects that is available to all UC Berkeley students. It is housed on the first floor of Moffitt Library in b.Makerspace and financially supported by the Student Technology Fund of the ASUC. Robotics@Berkeley began the library in 2017 to further achieve its mission of making hands-on robotics projects more accessible to Berkeley students.


We are looking to fill the Parts Library Manager role for the 2019-2020 academic year. Email for further details.
