Rules And Specifications

  1. The robot’s control should be gesture based (any gesture recognition technique like image processing, mobile application etc.). Locomotion and gripping must be controlled using  microcontroller of not more than 16 bits. Use of any kind of switches and buttons is not allowed apart from power supply.
  2. Atmost two people can control the semi-autonomous robot at a particular time.
  3. All arena dimensions have a tolerance of 10%.
  4. None of the teams will be allowed to see the run of other teams.
  5. Each team can consist of a maximum of 4 members.
  6. Each team should have unique participants i.e. no two teams can have even a single participant common.
  7. The team members can be from different institutes or colleges.
  8. The right spirit of participation is expected from the participants.
  9. The decision of the Team ROBOTIX will be final and binding.

Mines

  1. The mines will be metal plates 30 cm in diameter concealed under the arena surface.
  2. Out of the discs on the arena, the discs which are metal mines will have iron plate in between black chart paper and wooden disc. The black chart paper side is the side which will be visible to the participants.
  3. Once the mine is stepped upon, the mine depresses to few centimeters. This depression of mine is an indication that mine is stepped and the team will be penalised for the same.

Victims

  1. The victim will be a light wooden cube of side 5 cm, (the weight may vary) weighing less than 40 gms.
  2. The position of the victims will be completely random and decided by Team Robotix.
  3. The Victim would be considered to be completely rescued only when it is deposited in the safe zone. (however there will still be points for reaching the victim avoiding the mines).

Obstacles

  1. The obstacles will be wooden cuboids of dimension 5cm x 5cm x 10cm.
  2. The position of obstacles will be random and will be decided by Team Robotix.

Saving the Victim

  1. For saving the victim, the robot has to avoid all the mines and reach near the victim.
  2. The robot has to reach out to each victim , clasp it using the gripping mechanism and deposit it in the safe zone.

Robot traversal

  1. The semi-autonomous robot has to start from the start zone as marked in the arena.
  2. After it enters the arena, it needs to move according to the placement of mines and victims.
  3. The participant can not use simple push buttons or any kind of buttons for gesture recognition. Participant is required to control the bot on the basis of wrist movements and tilt of the palm.
  4. For the Time bonus to be awarded, it is essential for the robot to reach at least 2 Victims and deposit at least 1 in the safe zone.

Initial Orientation of Robot

  1. The participant is allowed to decide the initial orientation of his robot(s).
  2. Team ROBOTIX reserves the right to disallow any initial orientation of the robot inside the  starting  zone  if  it  gives  the  participant  an  undue advantage, solely based on the judge's discretion.

Restarts and Timeouts

  1. A maximum of 2 Timeouts of 1 minutes each may be taken. Penalty will be awarded for each timeout and robot will start from its last position on the arena.
  2. The participant's robots can have a maximum of 2 restarts. A penalty will be imposed on the team for every restart that they take.
  3. After the restart, the participant's robot will be set to its initial position. Timer will be set to zero and the run will start afresh with the addition of the penalty for restart.
  4. If the robot goes off track or outside the arena, then the team has to take a restart or call off their run.

TECHNICAL

  1. A standard 220 Volt AC power supply will be provided by Team ROBOTIX in the arena.
  2. It is suggested that the participant try to make a wireless robot. In which case the wireless bot should be battery powered on-board.
