Multimode Control of Wheeled Bot Using Python and Virtual Network Computing

Abstract

In this paper the design and development of multiple control interfaces of a mobile wheeled bot is presented. The controller is a Raspberry Pi Zero and the software platform is developed using Python. The bot has been programmed using Python and Virtual Network Computing(VNC) viewer. The multiple control interfaces include keyboard, Graphical User Interface (GUI) in desktop computer and VNC in mobile phone. The communication between the bot and the controller is wireless communication through a local network. One of the multiple control interfaces can pass the commands to move the robot. Experimental setup included five different paths in which the robot is made to move using each of the control methods. The response timings measured are noted and evaluated.
