The SDR’s exclusive bell-shaped fiberglass casing with streamlined surfaces allows disinfectant droplets to cover it entirely and fluids to drain away effectively during any disinfecting process. In addition, the absence of protuberances such as bolts and nuts on the SDR, commonly seen in similar robots, prevents foreign matter such as viruses from gathering and residing on its body.
Capable of shooting strong jets of disinfecting solution carrying chlorine or hydrogen peroxide, the robot is designed for killing coronaviruses. At about 8.5 microns in size, the disinfectant droplets are small enough to float in the air to increase treatment coverage.
The SDR can operate in two modes – remote control for affected areas and autonomous navigation for general disinfecting. For affected areas, the operator can use a joystick, tablet or mobile phone to remotely control the spraying of disinfectant into nooks and crannies, with the aid of two water-resistant cameras. For general disinfecting, the robot can assume the autonomous navigation mode with built-in lidar and ultrasonic sensors to avoid obstacles such as glass.
The robot can be used in both inhabited and habited spaces, an advantage over ultraviolet-C (UV-C) robots that require target spaces to be vacated due to health risks posed by UV-C light.
Measuring only 1.2 meters in height and 70.5 centimeters in width, the SDR’s compact form can fit into small spaces such as hospital rooms with ease. Capable of treating a space of 27 cubic meters, or 8.5 square meters by 3 meters, per minute, it can complete disinfecting a typical hospital room in about 15 to 30 minutes.
Maintenance for the SDR is made easy with built-in LED indicators for water level, battery power and error messages.
