In robotics, you need to control your robot with logics. In real world, the logics are handled by microcontrollers. You may have heard of Arduino, an open source hardware that deals with microelectronics. Basically, Arduino controls microcontrollers using C code. However, if you know JavaScript, you can also code for it; to work with microprocessor/microcontroller and make your first robot. You can get help from http://nodebots.io/ in order to see how JavaScript is used to build robots. Following is an image of Arduino UNO board:
