On their journey they were faced by a great conundrum; of crossing a vast ocean, the Indian Ocean. Coveting for his wife Rama along with his army built a floating bridge across the ocean, the famous Ram Setu.

  11. The bridge will be completed only if all the 12 balls have been dropped in to the slots.
  12. The red ball (final ball) will come out when the bridge is complete.
  13. After the bridge is made the robot has to cross it and get the final ball (resembling sita) and bring it back to layer 0. Where it has to be put on top of the pedestal to complete the event.

  • Tennis balls will be randomly placed in the boulder region.
  • The pedastal in layer-zero will be 10 cm high.
  • The slope to layer-one is 60.9 cm (approx) long with a 100 inclination.
  • Layer one is 80x80 cm in size.
  • The bridge connecting layer-one and layer-two has 16 cm wide void at the centre. the team will lose a trial if the bot falls into it.
  • On both side of the void there is slots each of 14cm wide for the boulders.
  • Glass/acrylic platform on outer most sides as aid when dropping the ball. each of them is 18 cm wide.
  • The red ball will come out only when the bridge is complete.the it will be standing on a 5cm high pedestal as shown in the pic.( see the red ball before and after completing the bridge)
  • Layer-two will be 70x80 cm in size.
  • The whole arena will be made of plywood and will be painted.


After dropping all the balls:







  • +20 for successfully placing each ball into the slot.
  • -5 if the ball misses the slot and falls outside the arena.
  • +30 for crossing the bridge.

  • The best of the three trials will be considered for the final scoring.


  • Bot must fit into a square of 40cm x 40cm initially.
  • The potential should not exceed 12V at any two points in the remote or the robot. How a tolerance of 2V will be considered for over charge.
