Robot Competition


This robot competition is based on two different tasks given below with small size robots and the image taken using a video camera placed on the playing field. Each robot will be controlled wirelessly by directional commands and the tasks will be completed in the shortest time and without any errors.


The competition will start on November 01 at 14:00. Teams will be given time to one day before the competition day in the afternoon, on the competition day in the morning to make arrangements and work.


The playground will be a platform with 1m width and a length of 1.5m with white lines on a green background, and a USB camera 1.5m above the platform. The teams will process this USB video camera image and transmit the necessary motion commands for the robots wirelessly. Each team can prepare their own robot and wireless system. Existing robots for demonstration purposes can also be used using the communication protocol. The ball to be used shall be 3cm in diameter in orange color. These robot structures and communication features are also given below.


The tasks to be applied in the competition are given below. It is not mandatory to participate in all tasks. Participants can register for the task they want or all tasks.

Tasks

  1. Penalty Shot

  2. In this task, the contestants will come from outside the penalty area and try to score goals by hitting the ball placed 30 cm away from the goal. During this time, the goalkeeper robot belonging to the platform will be moving. Each team is entitled to 3 shots. With each shot, the robot will have a single touch to the ball. The robot who misses the ball, is considered to have been hit. Evaluation is calculated as 20 points for each goal, 10 points for each ball hitting the goalkeeper, and 5 points for the ball going out. During the game, the robots with falling pieces or scattered will be deemed to have used their current shooting rights and they will be provided to receive service. At the end of the competition, the teams that can get the same points compete again with each other with two rights.

  3. Dribble

  4. In this task, the contestant robot will start the ball at the penalty point of his goal post starting from wherever he wants and try to direct the obstacle robots to the goal post. Here, each team will have 2 rights and the time will be stopped as soon as the ball crosses the goal line. This competition aims to be completed within the shortest time . The total duration of the 2 rights will determine the competitor's score. If the competitor robot touches obstacle robots other than the ball, the competitor is punished with 5 seconds. The position of 3 red obstacle robots will be determined during the competition. During the game, the robots with falling pieces or scattered will be deemed to have used their current rights as 60 seconds and they will be provided to receive service. At the end of the competition, the teams that can get the same points compete again with each other with one right.

Robots

The robots to be used in this competition can be up to 8 cm wide, 8 cm long and 8 cm high. No motorized equipment will be used to hit the ball, but the robot may be hit with the front, back or corner of the robot. There is no limit to the number or quality of wheels in robots. Each robot shall have the color codes specified by the competing team. Robots accepted to the competition after the technical examination will not be able to make any hardware changes that will change the design. However, deteriorated equipment can be replaced with the same.


The features of the robots that can be used by the team and will serve as goalkeeper are given below. These robots are equipped with an arduino nano microcontroller based nRF24 wireless transceiver. There are 2 N20 micrometal motors and 30mm diameter wheels on them. TB6612FNG Dual Motor Driver Board is available as motor drive. The 850mA 7.4V lithium ion battery provides energy.


Robots are working under constant PWM. Wirelessly received, code 11 in ASCII is used for forward, command 10 for reverse, command 12 for stop, command 13 for right turn and command 14 for left turn. Each command is processed for 100ms and the robot automatically executes the stop command immediately after it to prevent continuous movement. The sample contestant robot has one red circle and a blue rectangle on the front. Goalkeeper robot color codes are designed in reverse.
