Time Machine

Time. The most fundamental quantity without which nothing else can be explained.


There is an appointed time for everything. And there is a time for every event under heaven–
A time to give birth, and a time to die; A time to plant, and a time to uproot what is planted.
A time to kill, and a time to heal; A time to tear down, and a time to build up...
A time to love, and a time to hate; A time for war, and a time for peace.



Mankind has invented various devices to measure and keep track of time. Here is your chance to create your own invention to measure time. Get all your electronic gear out and use your bot building skills to create a bot that can 'see' a clock' and tell the time. Remember, taking a photograph is easy but we love the ones who differ from the oft-trodden path!

Design a robot to automatically detect the time and display it using a seven segment display or LCD.


  • The arena consists of 2 black coloured circles, of radii 90cm and 120 cm respectively and having a width of 3 cm each.
  • The circles are painted against a white background.
  • 12 equally spaced lines are drawn inside the circles representing the 12 numerals in the clock. Each line has a thickness of 3 cm.
  • Minute hand is represented by a block of dimensions 107 cm X 8 cm X 8 cm.
  • The hour hand is represented by another block of dimensions 77 cm X 8 cm X 8 cm.
  • The blocks are white in colour.


Arena specification

Bot Specifications

  • Maximum allowed size of the base : 20 cm X 20 cm X 20 cm
  • Voltage restriction: 12 V (External power supply can also be used)


The Game

  • The bot will be placed on the 12 o' clock line along the outer circle, at the start of the run.
  • The two blocks representing the minute hand and hour hand respectively will be aligned by the event co-ordinators to show a particular time.
  • For the sake of avoiding complications, the hour hand will be made to point exactly along the appropriate line, and will not be in between 2 lines. ie. for 5:15 and 5:45, the hour hand will be pointing along the 5 o' clock line in both cases.
  • The bot can traverse along either the outer circle or inner circle, or along any of the line indicating the numbers on the clock.
  • Once the bot has computed the time, it has to align itself along the 12 o' clock line (can be on the inner circle or the outer circle) and display the time.
  • 4 members per team (the members may be from different institutions).
  • Only pre-registered teams can participate.
  • Registration is Closed
  • Image processing, remote controls etc SHOULD NOT be used.
  • The bot at any point of time should not collide with the blocks (minute and hour hand). Doing so will attract a penalty.
  • The bot should not cause any kind of damage to the arena at any point of time.
  • On the evening before the event, teams will be allowed to calibrate their sensors.
  • 2 trials per team.
  • Each trial will last for 5 mins.
  • Initially each team will be awarded 500 points.
  • 5 minute deviation from the actual time will result in a 10 point deduction.
  • Collision against a block will result in a 50 point deduction.
  • When the final time is displayed after the bot is aligned along the 12 o' clock line, the team will be awarded 100 points.
  • Judges’ decision is final and binding.
