Problem Statement Our goal is to develop a cart that houses all the components for monitoring an electroencephalogram (EEG). The cart should be designed with respect to ergonomic standards to facilitate easy workflow to ensure the comfort and safety of the users, while maintaining a compact footprint and low production costs.
