Robots have become an integral part of the modern society. Be it for social security, medical aid or relief work in calamities. Unmanned robots are used for surveillance, while the manually controlled robotic arms find applications in nuclear waste disposal, garbage disposal and earthquake relief. Isn’t it time to bring them into the field of sports? If you have ever dreamt of being Kobe Bryant or Michael Jordan or, have always desired to play Street Ball but haven’t been able to; put on your thinking caps and let your robots do what you have always wished. Come, this Pragyan, we give you the opportunity to build a manually controlled robot basketball player and compete with other like-minded people to test if your robot is faster at, ‘Slam Dunk’. Let’s make it more challenging: you have to guard your own basket with an autonomous robot and ensure that the opponent doesn’t detect your manual robot. Are you ready?

NOTE:

• Kindly read the pdf. The entire details of the event have been put up.
• Please read the FAQs.

Registrations open now.

Problem Statement :

• Each team must build an autonomous bot and a manual bot.
• The teams will duel against each other to win matches viz. team A and team B. 
• Team A has to try putting the ball in the Team B’s basket while Team B prevents Team A from doing so and vice versa.
• The autonomous bot just needs to be a two sensor line follower with a object detecting sensor.
• The manual bot just needs an electromagnet to lift the cube.

Note: Please read the conditions to win a match in the judging criteria under the rules and regulations.

Arena:

The area is of dimensions 6500 mm x 3000 mm which is surrounded by a wall of 100 mm and 20 mm thick. The manual bots have to start at the zone in green. The balls are kept in the centre of the arena in a circle.

The balls are placed on the poles which are 80mm in diameter and 380 mm in height. The baskets red and blue are at a height 360 mm and 50 mm diameter.

A thick annular black region 350 mm thick is provided on which there is a white line which is 50 mm thick for the autonomous bot to go in circles.

There will be a barricade at the exit of the basket zone as shown and the inner periphery of the black annular region to ensure autonomous bot does stay at the basket or come out of the zone.

NOTE: Kindly refer to the figures in pdf for the 3-D view.

Physical Constraints:

MANUAL ROBOT

Maximum size at starting 30 X 30 X 50 (in cm). If the robot is not wireless it must have a pole of at least 60 cm from the ground from which the control wires have to be taken out. Maximum weight of the robot is 7 kg including the controls.

Note: Only the pole is allowed to breach the size limit initially.

AUTONOMOUS ROBOT

Maximum dimensions at any point of the game 25 X 25 X 45 cms.

Power Specifications:

• No external supply is allowed.
• On-board power supply for both the robots.
• Maximum potential difference across each motor is 12 V.

Cube Specifications

The ball has been modified to a cube to ensure maximum surfac e area for the magnet. The cube will be of side 30mm and weigh around 70 gms.

Judging Criteria:

• The autonomous robot of each team guards its own basket by indicating the presence of the opponent’s manual robot by means of lighting an LED, bulb, sound or by any other method when the opponent’s manual robot is in the basket zone. This is called frag.
• A frag is considered valid if : a) The autonomous bot is completely inside the black annular region b) Any part of the opponent’s manual bot is inside the outer black circle. (Refer the fig for more information about the zones where the autonomous and the opponent’s manual bot must be placed for the frag to be valid.)
• Under all othe situations the frag is considered invalid. · A frag gets the autonomous bot’s team 5 points if it’s valid and -2 if its invalid.
• One point is scored by the manual bot if it enters the basket zone without getting fragged.
  However, no extra point will be given for staying inside the zone
• A manual bot wins if it puts the ball in the basket without being fragged by the opponent’s bot and comes out of the basket zone
• Incase both the teams fails to put the ball in the basket then the team with max points (due to frags) wins.
• Each match will consist of 3 rounds with a time span of 5 mins. The team which wins 2 rounds is declared winner of that match.
• The format of the tournament is either knockout or league depending on the number of teams.
• Teams will be considered for the tournament only if their a) autonomous bot can complete a circle around the basket b) the autonomous bot must be able to frag c) the manual bot is able to lift the ball

Rules and Regulations:

• A team can have up to 4 participants with a valid ID card of their institute. The team members can be from different institutes.
• The autonomous bot can start anywhere inside the black annular region of their basket.
• The starting zone for the manual bot is either of the green patches shown in the arena.
• Both the manual and autonomous bots have to start completely inside the starting zones allotted to them.
• In case of a valid frag or collision between the manual and autonomous bots inside the black annular region, the manual bot has to come out of the basket zone and the autonomous bot can be restarted.
• If an invalid frag has been made the game continues without interruption.
• No restarts are allowed for the autonomous bot once the round has begun. In case it fails to work at any point of the game, participants are allowed to remove the bot from the arena.
• Any intentional damage done by one bot to another bot may lead to disqualification from the event.
• Manual bot can be wired or wireless.
• In case the robot is wireless, please have variable transmission frequency so that it doesn’t interfere with the opponents bot.

• Is a lifting mechanism required for the manual bot?
  No. The metallic material which can be easily lifted by an electromagnet. Therefore, a lifting mechanism is not required.
• Should the autonomous bot be a line follower?
  No. The autonomous bot need not be a line follower. It just has to say in the region specified.
• Should the ball be launched?
  It’s not required. The height and the diameter of the ring would be such that the ball need not be launched. It can be easily dropped.
• What will happen if the manual bot touches the autonomous bot?
  It will depend on the discretion of the judges. The judges may either ask you to re-start and if the offence is serious the judges may disqualify you.
• Can the manual bot be wired?
  Yes but there are specifications. Do read the rules carefully.
