Problem StatementProblem Statement

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