Designs for modular microsurgical robotic devices and systems are provided, which could include one or multiple master-slave units coupled to a central microscope-based suspension structure. One of the main objectives is to provide robotic assistance during tasks which require long-term user concentration and high precision. The microsurgical robotic devices pay attention to motion scaling and tremor filtration in a 6 Degrees-of-Freedom (DOF) master-slave setup with force feedback. An extra DOF is included to actuate a 1-DOF instrument tip. Embodiments of this invention can be used in the medical environment as well as in other areas such as printed circuit board repair, watch and jewelry making, laboratory tasks, or other areas which require high precision over extended periods of time.
