//-->iBot – Robotics Club of IIT MadrasTutorial 1.1.1Build Your Basic BotiBot is a Robotics Club of Indian Institute of Technology (IIT), Madras incubated at Centre forInnovation (CFI).iBot has been there since few years and has undertaken many challenging projects.1) RoboconFigure1: Manual and Autonomous Carrier robots carry traveller robot to the drum zone.Robocon is considered one of the most prestigious Robotics events in India. Robocon isa national and international level Robotics competition held every year in the month ofMarch. IIT Madras has been continuously participating in the same for last 5 years. Everyyear, the problem statement is released by one of the Asian countries on the basis oftheir culture and tradition. A winning team in nationals gets a chance to represent Indiain internationals which is held in host country. In year 2009, the hosting country wasJAPAN. Problem statement was based on the ancient Japanese custom of Kago.Figure2: Manual RobotRobocon 2009 was the prestigious one in the history of IITM Robotics. For the first time,our institute earned a privilege to represet india at Roboocn 2009 atTOKYO, JAPAN.After an uninspiring performance at the group stages, the underdogs turned giantkillers, performed brilliantly at the knockstage and finally emerged victorious.People all over India watched scenes of joy in the team camp, as IITM also bagged‘Thebest design award’.1. Lets Get StartedThere are many ways by which you can get involved in technical activities in ourinstitute.1.1 Tech Soc – Techsoc is a series of inter hostel technical competitions including bothindividual and mass events .To involve yourself in it, contact respective TechnicalAffairs Secretary (TAS).1.2 You can be a part of any of the ongoing projects provided there is a vacancy for thesame. For this, you will have to personally contact one of the project team members.1.3 If you have an idea which you always wanted to turn it into a reality, you can goahead and inform one of the iBot members, list of which is provided at the end ofthis tutorial.1.4 Become a Robotics Club Member – You can apply for being a robotics club member.iBot expects some kind of basic knowledge and experience, enthusiasm andcommitment towards Robotics. One of the ways by which you can gain experience isbuild your own basic robot as described in this tutorial.We will try and make a simple remote controlled robot which can be made to move inany desired direction. This is just to get you started and gain enough momentum so asto push you to higher level projects or even propose your own ideas. Remember, thestart has always been the trickiest part. Once you are through the first basic levels, youget a knack of it.Before we start, you can form teams of 4-5 who are determined to ‘MAKE THISHAPPEN’.First thing that you require is to have a basic understanding of all the required tools.2. Tools Required:2.1 Hacksaw or Jigsaw2.2 Hand drill or Power Drill2.3 Spanners2.4 Pliers2.5 Screwdriver2.6 Wire stripperHope you all are familiar with these tools and know how to operate on them. If not,spend some time in doing so.3. Differential Drive System (Robot Locomotion)As suggested by its name itself, the independent control of both the driving motors(both front and back) is called differential drive. With the combination of four switches,i.e,4.5.6.7.Left motor frontLeft motor backRight motor frontRight motor backbot can be made to move in any desired direction. Following table shows the resultantdirection in which the bot moves when a particular combination of switch is pressed. [ Pobierz całość w formacie PDF ]
