Poles Apart

Manual Robotics Event

Problem Statement

To build a manually controlled robot, which is capable of picking and placing blocks with accuracy and changing its interaxial distance to make its way through a series of hurdles.

USP

  • Changing interaxial distance.

  • Gripping and lifting mechanism.

  • Placing blocks in their respective places.

Task

Round 1
  • Complete its way up a slope by picking blocks from an adjacent area and placing them in their respective slots.

  • The block 1, block 2 and block 3 are in increasing order of their height up the slope and have different points for each.

  • Place two horizontal planks on pillars to make a bridge to cross a valley (dimensions mentioned later).

  • Cross another path by using 2 planks which will already be placed over it.

  • Cross a path which consists of two planks placed at an angle to each other such that, the distance between them changes continuously in a diverging pattern.

  • Cross a path which consists of two planks placed at an angle to each other such that, the distance between them changes continuously in a converging pattern.

  • Make its way down a slope, comprising of two planks.

Round 2
  • Complete its way up a slope by picking blocks from a circular rotating table and placing them in their respective slot.

  • The Block 1, Block 2 and Block 3 are in increasing order of their height up the slope and have different points for each.

  • Place 2 horizontal planks on pillars to make a bridge and cross a valley.

  • Cross a path with two circular planks of constant radius making an arc.

  • Make its way up a slope made of two planks which will be at an angle to each other in a converging pattern.

  • Make its way down a slope made of two planks which will be at an angle to each other in a converging pattern.

  • Make its way down a normal slope to the end.

Note: If at any point the robot drops from the arena, a penalty of 50 percent of the existing points will be made, if the robot wishes to start from the same point. Otherwise, there is an option for rerun of the robot.

Rules and Specifications

General Rules
  1. All arena dimensions may have a tolerance (error) of up to 10%.

  2. Each team can consist of a maximum of 4 members.

  3. Only 2 members per team will be allowed to control the robot.

  4. The participants will be provided with 220 volts, 50 Hz standard AC supply.

  5. Each team should have unique participants i.e. no two teams can have even a single participant common.

  6. The team members can be from different institutes or colleges.

  7. Teams qualifying the first round will go into the second round.

  8. The teams cannot touch their robot during the course of the run, unless timeout is taken.

  9. The best spirit of sportmanship is expected from the participants.

  10. The decision of Team ROBOTIX will be final and binding.

Arena and Locomotion
  • The robot has to start from the start point, which will be marked in the arena.

  • Penalty will be awarded every time the robot falls off the arena.

  • The robot has to go and complete the tasks as specified above. Any discrepancies will be handled by Team ROBOTIX and their decision will be final and binding.

  • Time will be kept by Team ROBOTIX and their decision will be final and binding.

Initial Orientation of Robot
  • The participant is allowed to decide the initial orientation of his robot on the start zone.

  • 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 Team ROBOTIX’s discretion.

Restarts and Timeouts
  • A maximum of 2 Timeouts of 1 minute each may be taken in each round. Penalty will be awarded for each timeout and robot will start from its last position on the arena.

  • The participant’s robots can have a maximum of 1 restart per round. A penalty will be imposed on the team for every restart that they take.

  • 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.

  • A timeout can be taken anytime at the participant’s discretion.

  • A restart can only be taken if there is a genuine technical fault in the robot. Team ROBOTIX may refuse a restart if the reason is not genuine enough, and their decision will be binding and final.

Robot Specifications
  • Each robot can have maximum dimension of 30 x 30 x 30 cubic cm (L x B x H) respectively.

  • No part/mechanism of/on the robot should exceed the given dimensions before the commencement of the event run. The robots can exceed their respective dimensions once the event commences, due to elongation of arms/gripper/forklift. However, Team ROBOTIX gets the final say in deciding whether the advantage is fair or not.

  • There is no weight restriction on the robot.

  • LEGO kits or its spare parts or pre-made mechanical parts are not allowed.

  • Ready-made gearboxes, sensors, development boards can be used but no other part of the robot should contain any ready-made components. Simple car bases with no extra features may be used.

  • The bots should not damage the event arena in any way. If it does so, a penalty will be imposed on the team. The magnitude of the penalty will be decided by Team ROBOTIX.

  • Ready-made gripper is also allowed.
