Advanced Design for Robot in Mars Exploration P. Pradeep, M Prabhakaran, B. Prakash, P. Arun Kumar, and G. Gopu Department of Electronics and Instrumentation Engineering Sri Ramakrishna Engineering College Coimbatore-641022, Tamilnadu, India Abstract Mars Planet Exploration requires a new design of robot to explore it in a new way. This robot has been equipped with specially designed wheels to overcome all possible obstacles. In other words it helps to explore the unknown land in the mars especially the craters. This robot has a special type of plates mounted on the wheels, which can pass over all obstacles, especially suited for mars. The instruments inside the robot will be protected by suspension system in wheels. It can extend the life time of the Robot, saves instruments in it from physical damage. This robot will be having a extra setup to explore craters. Since DTMF technique has high coverage area as per service provider it helps this robot to be used in the field of military and forest application. It is first time using a mobile phone to control a robot with 3G technology. Keywords Specially designed wheels, Extra setup, Mars, DTMF, 3G Technology 1. Introduction The robot that had been sent to space still now has suffered a lot in overcoming obstacles like stones on the path. So they decided to avoid the obstacles by taking different path or route. This methodology worked for several areas in MARS but not for the craters and other rough terrain surface. Our aim deals with this problem. We have designed a robot whose wheels can overcome all types of obstacles and an extra wheel setup to explore craters. Also this paper would be a fundamental, to design a Rover Robot for the upcoming missions like CHANDRAYAAN-2 and MARS Robot by ISRO. 2. Specially Designed Wheels The specially designed six wheels help in overcoming obstacles in terrain surface. The Rover Robot has six specially designed wheels. The structure of wheels is shown in the figure 1, it consist of has 1)six wheels, 1 A)suspension system, 2)additional wheel setup, 3)dish to transmit and receive signals, 4)antennas, 5)four cameras, 6)extendable arm 7)scientific instrument. The wheel has a plate like erected arrangement which supports the robot in overcoming obstacles. It can cross the stones of height equal to the wheel height. The wheel has a diameter of 30cm. The height of the plate is 7cm and the width is 5cm. Each wheel has its own individual motor attached to it. The speed of the robot is 1inch/sec. using this type of wheels it is easier to explore the rocky or rough terrain surfaces in MARS. 3. Exploring the Crater Using Extra Setup The additional wheel setup is to explore the craters or deep trenches. The cameras are used to view the surface. Let us see another important work of our Robot in exploring the crater. Crater is a bowl-shaped cavity or hollow shaped cavity in the surface of the planet caused by impact. It ranges from meters to miles however we focus on exploring the craters up to 1000 meters deep. Normally a Robot cannot enter this deep crater as its fall causes damage to the robot. So still now they are left unexplored. In our design we have a special setup to use in that situation. This setup has two wheels, a spoon to take samples and rope tied to the extra setup which can be elongated as well as shrinked as shown in figure 2, it consist as follows 1)plates, 2)spoon, 3)rope, 4)two separate motors.. The other end is attached to motor which rewinds and forwards the rope by moving motor clockwise and anticlockwise direction.
