Medical Robotics =

Robotics to assist doctors / surgeons

Assistive technologies

Robots and machines that improve the quality of life of disabled and elderly people, mainly by increasing personal independence

Robotics for surgery, exploration, diagnosis,

therapy...

Rehabilitation robotics

Robots and mechatronic tools for clinical therapy in neuro-motor rehabilitation, training...

Robotics to assist people

Outline

3rd SSSR, E. Dombre, Introduction to Surgical Robotics (5)

? A short overview on assistive technologies &

rehabilitation robotics

? A more detailed introduction to surgical robotics

3rd SSSR, E. Dombre, Introduction to Surgical Robotics (6)

Physical capacity

Real curve Ideal curve Area to compensate

Physical capacity along time

1: detect the failing as soon as possible 2: compensate close to the 100% of capacity 3: continue the maximum of capacity as long as possible

elderly ? adding quality of life to aging

age

Goal of AT: provide tools to

Physical capacity

improve or restaure physical

performance

disabled ? Compensation of the disability
