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.
