DESIGN OF A DIFFERENTIAL DRIVE MOBILE ROBOT PLATFORM FOR USE IN CONSTRAINED ENVIRONMENTS

 Mobile robotics is a growing trend in recent years as mobile robots are being used in service as well as industrial sectors. This paper introduces a novel d esign of a mobile robot platform for use in constra ined workplaces. The constrained environments are nothin g but congested places,for example hospitals,ware houses,offices,shop floors where various equipmen ts and machineries are to be arranged in small area s. For robots mobility in such places,various methods are being used such as differential drive system,Omni- directional mobility etc. This paper presents the d esign of mobile robotic platform with application o f the differential drive system for enhancing mobility of the robotic platform. The 3-D Model of mobile robo t is prepared in CAD software CATIA V5R19. The shape of the robot is selected as rectangular,with two driving wheels and two caster wheels. The driving w heels are located at the front side of the robot,w hich helps the robot to drive on to the slope. Two cast er wheels are attached at the back side of the robo t for stability purpose. In this robotic platform,the tw o driving wheels are driven by using independent mo tors,for forward,backward as well as rotational motion.
