DESIGN OF ROBOTIC SYSTEM FOR ACUTE WOUND CLEANING
GOAL
PURPOSE
To design an automated system to clean acute
wounds in hospital settings
Wound cleaning is a repetitive, time
consuming and tedious process, which is
often neglected. Proper cleaning ensures
removal of dirt, devitalized tissues and
bacteria from the wound. It also curtails
further contamination and spread of
infections over the wound.
WOUND CLEANING
The process involves exposing the wound to a
pressurized fluid, commonly saline water or
tap water., either continuously or in a
pulsated jet form until all the contaminants
are removed.

CHALLENGES
1. Design of manipulator
2. Wound irrigation system design
3. Wound detection
4. Manipulator control
5. Waste collection system
CONTROLLER
•Arm Motion Control
•Irrigation Control
MANIPULATOR
SUMMARY
The idea is to automate the process of wound cleaning using a low cost robotic arm. In
this system, the wound is detected by a vision system, which captures images of the
wound. These are processed to obtain quantifiable information of the wound such as its
location, area and the severity. The controller then actuates the arm and the wound
irrigation system to clean the wound.
