    Introduction
    Autonomous robots are robot that can perform desired tasks in unstructured environments without continuous human guidance. Many kinds of robots have some degree of autonomy. Different robots can be autonomous in different ways. A high degree of autonomy is particularly desirable in fields such as space exploration, cleaning floors, mowing lawns, waste water treatment etc. A fully autonomous robot has the ability to:
  • Gain information about the environment
  • Work for an extended period without human intervention
  • Move either all or part of itself throughout its operating environment without human assistance
  • Avoid situations that are harmful to people, property, or itself unless those are part of its design specifications
    • One important area of robotics research is to enable the robot to cope with its environment whether be on land, underwater, in the air, underground, or in space. Some modern factory robot is "autonomous" within the strict confines of their direct environment. They may be asked to find the exact orientation and position of the work object and even the type of object and the number of object. This can vary unpredictably (at least from the robot's point of view). So we bring you a problem where your robot has to find the number of block present inside the grid arena.

    Problem Statement
    Build an autonomous robot capable of following black line over a white background and counting the blocks placed inside the grid boxes.

    Arena Specifications:

    • The arena consists of white sheet over which grid of black lines of 1 inch width is drawn. Each grid box measures 30cm * 30cm.
    • There will be 10 such grid boxes in each row and column.
    • A block will be placed at the centre of the grid boxes in symmetry to grid box. The block will be white in colour and measures 4cm * 4cm * 8cm.
    • The total number of blocks placed in the arena to be counted will be <=15, it varies from team to team.
    • The below figure showed is an example, the position and number of blocks varies at the time of event.

    Robot Specifications:

    • The robot should fit in a box of dimension 20cm X 20cm X 20cm.
    • The robot should not use power source exceeding 18V.The power should be on-board.

    Gameplay:

    • The robot will be given a total time of 5 min.
    • The robot will have to begin from the line 'start' and end at line 'finish'.
    • The robot should count the total number of blocks in the grid arena and display the result (number of blocks) on a LCD display or seven segment display or in Binary code (i.e. using 4 LED's). Display in Binary is explained in next section.
    • The robot should be able to negotiate 90 degree turns as well as intercepts.
    • The team has to reach the 'finish' line with correct count of the blocks placed in the arena.
    • In case if none of the teams are able to show the correct count, then the team displaying the result close to the actual count will be considered as the winner.
    • In case of tie, time is considered and the team finishing the task in minimum time will be declared winner.
    Display in Binary Code

    General Rules:

    • A team may consist of maximum 4 members. Students from different college may form a team.
    • The robot should not damage the arena.
    • Teams should report in time otherwise it may lead to disqualification.
    • Only one member of the team will be allowed to be near the arena at the time of starting the robot.
    • Any robot not conforming to the given specification will be immediately disqualified.
    • In any case the decision of judges will be final.
