A mobile robot for hospitals controlled using WLAN

This paper presents the design and prototype construction of a remotely controlled mobile robot which can be used in a hospital environment. The robot relies on the hospital WLAN for remote control and transmission of data in both directions between the robot and the control room. Lifting, handling and transporting radioactive materials within the hospital is one of the primary functions carried out by the robot. This function is important to reduce the exposure of hospital staff to harmful radiation. Another function of this robot is audio-visual patient-doctor communication even when the doctor is unable to be physically at the hospital. In case of WLAN failure, the robot can be controlled manually using a joystick. The robot can be easily manufactured at low cost and hence has the potential for commercial production and a wide distribution in local and regional hospitals.
