The CAD drawing of the overall mechanical system is
shown in Fig 2. The system can be separated into three
independent modules: they are the MCP joint module, the
PIP joint module and the DIP joint module. Micro-geared
DC motors (Pololu HP series) have been selected for all the actuation modules because of their high torque to weight
ratio, which allows a compact and lightweight design. A
detailed descriptions of the modules is presented in
subsections C and D
