Elementary students in the remote Linyuan District of Taiwan’s most southern city, Kaohsiung, built a robot out of Legos that automatically disinfects their hands to help combat coronavirus. The adorable automatic disinfectant dispenser also gives positive reinforcement as it dispenses by saying, “Washing hands is super!” using a recorded voice.
Guided by a robotics coach, the students who range in age from 6 to 12 years old, used application software to control the motor and the ultrasonic sensors. The ultrasonic sensors detect the children’s hands and dispense alcohol disinfectant from a spray bottle by pulling back its handle with a motor and gearwheel mechanism.
