The robbers have robbed the bank and now are hidden in the grid of city streets. But no
matter how smart the criminal is, he always leaves some clues behind. Now is the challenge
is to gather the clues, find the robbers and send them to the prison. This is the time to catch
the robbers and win the rewards. So, TECH A STEP……
1.To make the competition more interesting, we have made some changes in the gameplay. The event has been divided in two rounds. For details, please refer to the ‘Problem Statement’ tab.
2.Four teams have been directly selected for the Round 2 on the basis of their performance during the ‘Sixth Sense Arduino Robotics’ workshop conducted at VNIT, Nagpur on 31/08/2013 and 01/09/2013.
Note: Minor changes have been made(changes are highlighted)..Please refer to the problem statement
Teams must build an autonomous bot which can find the correct coordinates and navigate in the grid by the principles of line following.
1. The arena is composed of two parts:
Part 1: In this area, there will be grid like structure in which there will be six nodes (intersection of two perpendicular lines) numbered from 1 to 6. Any two of these will be coloured white whose position might change. The lines will be of black colour on a white background and the width of the line will be 30mm.
Part 2: In this area, there will be a white surface with black grid (5 x 5) lines of width 30 mm, i.e. co-ordinates of the nodes in this grid will be ranging from (1,0) to (5,4).
2. There will be 5x5 gridlines on the part 2 arena.
3. The distance between two consecutive parallel lines will be approximately 300mm everywhere in the arena.
4. Separate arena consisting of a small grid with some white nodes will be provided to the teams for the calibration purpose before the actual run.
1. The bot has to start from the starting point in part 1 and move through the path having black lines to reach the origin of the grid lines in part 2 (figure 1). The path will contain white nodes in different sets.
2. The bot has to save the number assigned to the white node came across the path, say N1 and N2.
3. The bot has to display the number assigned to the each white node when it reaches there using LEDs on the bot. The bot has to display this number till it reaches the next white node or the origin of grid in part 2 arena.
4. Round 1 finishes once the robot reaches the origin.
5. Based on the scores in Round 1, some teams will be selected for Round 2.
6. The selected teams for Round 2 have to start their run again from the starting point and have to reach the origin same as Round 1.
7. Using the saved values N1 and N2, the bot has to calculate the co-ordinates (X, Y) in the grid where it has to reach once it crosses the origin.
X = (N2 – N1) and Y = (N1 + N2)/2.
8. Once the bot reaches this co-ordinate (X, Y), it has to stop there. Then it has to display the X co-ordinate for five seconds and then display the Y co-ordinate for next five seconds using LEDs on the bot.
9. Once the co-ordinates are displayed, the bot has to exit the grid from the co-ordinate (5, 4) in the specified direction (Figure 1).
When the bot completes path in Part1 arena i.e. reaches origin.
1. Only one autonomous bot per team is allowed which can travel in part 1 and part 2 arena.
2. Once the autonomous bot starts, no team member is allowed to touch the bot.
3. The autonomous bot must fit into the box of dimension 250mm × 250mm × 250mm at the beginning of the run.
4. Bot must be started individually by only one switch. However, a team may have one on-board switch for restart. This switch has to be shown to the organiser before the run.
5. During the run, the autonomous bot can expand itself provided it does not damage the arena in anyway. However, it is not allowed to leave anything behind or make any marks while traversing the grid. Any bot found damaging the arena will be immediately disqualified. The final decision is at the discretion of the managers.
6. Bot may have an on-board or an off-board power supply.
7. When using the electric power supply, the voltage at any point on an individual component must be lower than or equal to 24 V DC at any point of time during the game.
8. Total number of LEDs to be used on the bot must be 6, for identifying white nodes in part 1 arena and co-ordinates in part 2 arena. The LEDs should be placed on the top surface of the bot such that they will be visible from distance.
9. The autonomous bot must not split into two or more units. All bots/units which are touching each other or are in the starting point will be considered as one bot.
10. Bot cannot be constructed using readymade Lego kits or any readymade mechanism. But, they can make use of readymade gear assemblies. Violating this clause will lead to disqualification of the team.
11. The starting procedure of the bot should be simple and should not involve giving the bot any manual force or impulse in any direction.
12. Teams are allowed to use ready-made microcontroller development boards and sensor.
13. The bot must be completely autonomous and should not receive any input from outside the arena.
1. Before the task, teams will be given 5 minutes time to do any hardware changes and calibration of the bot if they wish.
2. At the start of the task, the bot will be placed at the starting point. Only 2 members from the team are allowed to be near the game field while starting the bot.
3. Timer will start when the organiser gives the signal to start.
o A maximum of 3 restarts will be given to the team during the match.
o If a team asks for a restart before checkpoint, the bot will be placed at the starting position of part 1 arena.
o If a team asks for a restart after checkpoint, the bot will be placed at the starting of part 2 arena.
o In a restart, the timer will not be set back to zero and will not be paused.
o During a restart, a contestant must not feed information about the grid to the bot. However, contestants are allowed to adjust sensors (gain, position etc.) and make repairs.
A contestant must not alter a bot in any manner that alters its weight (e.g. removal of a bulky sensor array or switching to lighter batteries to get better speed).
In case of any discrepancy, the organisers shall arbitrate.
5. The LEDs should be strictly of high intensity and visible to naked eye.
6. Only 2 members of the team are allowed to handle the bot.
7. Participants are not allowed to keep anything inside the arena other than the bot.
8. Laptops/personal computers are not allowed near the arena. Other Wi-Fi, Bluetooth, etc. devices must be switched off. The organisers hold the right to check for these devices and their usage and disqualify the team if needed.
9. The time measured by the organisers will be final and will be used for scoring the teams.
10. Time measured by any contestant by any other means is not acceptable for scoring.
11.The locations of the white nodes in the part 1 arena will be totally random and arguments regarding that will not be entertained.
12. In case of any disputes/discrepancies, the managers’ decision will be final and binding.
13.Note that at any point of time, the latest information will be that which is on the site. However, registered participants will be informed through mail about any such changes.
14. Participants have to bring their own laptops during the competition.
1. If a bot successfully detects the white nodes in part 1 arena and glows the corresponding LEDs, the team will be awarded 10 points for each node.
2. Team will be given 30 points for reaching the checkpoint i.e. origin.
3. Team will be given 50 points for moving to (X, Y). 30 bonus points will be awarded if it glows the proper LEDs for X and Y co-ordinates.
4. Team will be given 70 Points for reaching to the extreme coordinate (5, 4) and leaving the arena in specified direction.
5. The team which completes the task with maximum points will be the winner.
6. In case no team finishes the task, team with highest points will be the winner.
7. In case of a tie, the team with least time will be the winner.
A team may consist of (a maximum of) 4 participants.
Students from different educational institutes can form a team.
All students with a valid identity card of their respective educational institutes are eligible to participate in the event.
