  1. DRILL-ROILLA

  2. 1. Problem Statement The participants have to design a manually controlled robot which may rover around an unsymmetric terrain similar to real life rocky, coarse hill state. It must also be able to drill through ground at specific locations in the arena and also collect sample present underneath. (having three layers made of articles of different texture and hardness). Besides it must also have a suction mechanism to suck liquids at marked locations.

  3. 2. Objectives : • Designing • A driving Mechanism which may move on coarse ground. • A Drilling Mechanism to do drilling and • A Suction Mechanism with basic • Power supply

  4. 3. Dimensions • The terrain will be spread across an area of 2.5m * 2.5m and will consist of sand, rocks, craters and pebbles of height not exceeding 3-4 centimeters. • The drilling spot will be marked red and will have an area of 3cm*3cm. It will be made up of only thermocol (of thickness not more than 3cm) or thermocol reinforced with corrugated paper (thickness not more than 0.5cm). • The depth of the bottom most surface liquid will not be more than 5 centimeters. • The liquid will be colored water or oil. • The dimensions of the arena are subject to a tolerance of 10 percent.

  5. ARENA# This is a rough picture of the arena which stated in the problem statement has the dimensions (2.5 *2.5 )m2 with pebbles ,stones and debrises scattered all around. # The red marks will be (3*3) cm2 all around the arena at random intervals .

  6. BotDimensions 1. Robot should fit into a box of dimensions 40cm x 40cm x 40cm (l*b*h). No part/mechanism of/on the robot should exceed the given dimensions at starting of the run. However the robot can change its dimension itself after the starting of the event. 2. There should be a transparent container to collect the sample which should be visible from outside. 3. The outer diameter of the wheels should not exceed maximum dimension of 10 centimeter. 4. The maximum allowed weight of the robot is 10 kg. 5. In case of any technical problem, the team can have a second run, but with the deduction of 20% points. No appeals can be made after a rover fails to run in the second attempt.

  7. 4. Mechanisms 1. The basic features to be looked upon in order to meet all the requirements of the problem statement are as follows : a. strong driving system . b. A drilling mechanism installed c. A suction mechanism inbuilt With all these features the bot becomes ready to be used. Now the accuracy and efficiency would be judged to qualify with flying colours

  8. a. The Driving mechanism # It can be a simple differential drive. It comprises of chasse having wheels and motor connected with a control box (which is an organized assembly of switches, wires ). # But as to enable it to move on coarse ground, some points must be kept in mind. Such as: # The motor to be used must be of high torque so that it may take the load of the high opposition while movement.

  9. # For better grip and result inspiration for wheels may be taken from Mars rover which is a wheeled vehicle for rough terrain.

  10. b. The Drilling mechanism 1. The drilling mechanism is one of the direct applications of using motor and its swiftness. 2. The easiest way to make one is by using a screw and attach it to a motor shaft. When the motor is given power then it may act as a driller. 3. The method stated is given in figure below. 4. We would rather look up for a more innovative method which is easier to control.

  11. 5. This is easy to make and the most probable method of drilling . 6. What we need is just to have complete control on it so that this drilling may become directional as well .

  12. c. The suction mechanism: 1. In the field of exploration a feasible suction mechanism is the need using which we may not only exploit the resources but even ensure cleaner application. 2. To do this there are few initial steps comprising of conversion of rotational energy to translational energy. 3. The most basic way to do this may be to use a motor connected to a disc. This disc in turn has a extruded end fixed at one of the edge.

  13. 4. This figure states the above mentioned mechanism clearly . 5. Now the other part of our objective to get a suction mechanism built is easy going . 6. The easiest ways may be through using any general use spray bottle or for more power a cooler pump .

  14. 7. After this assembly is required where your skill will be judged and will make your robot above other robots. 8. What else is left is good judgement of power supply and components to be used . 9. Wishing you all the best for the upcoming events .
