"I use two mobile phones to control the robot. One is connected with robot, it acts as call receiver, and another is used to send signals and acts like a remote control," Tushar Sarin, a class VIII student claimed at a press conference here.
He also demonstrated his self-made robot here.
Tushaar said he is working on a couple more things, which he claimed will have "great practical application."
"I am now making a fire alarm and a smoke sensor. These things can be installed at public places and have great practical application," he claimed.
