In this task assigned by the ROBOISM club of IIT-ISM(DHANBAD) I have made a three wheeler bot in solid works. Initially I have constructed a base for the bot and the one by one I have constructed the parts in bit by bit manner and assembled them one by one. I am initially uploading the file in component manner and later on I will add the dimensions too. For now the base is of 150210 mm and ultrasonic sensors are of 4520 with the circles of radius 8mm.
