Want to make a splash at Engineer 2011? This year Proteus brings you the ultimate water bot competition where bots have to maneuver around a course while collecting ping pong balls which finally have to put through rings while taking time into account. A simple event, this is meant for anyone who can think smart and think simple. Read on!

• The students must carry valid student ID cards of their college which they will be required to produce at the time of registration.
• A team may comprise a maximum of FOUR participants.
• Readymade kits are NOT allowed.
• The team is not permitted to compete with more than one bot.
• Teams will not be allowed to modify their bots during their trial.
• Judges’ decision in this regard will be final and binding.

• The bot has to start the event from the START ZONE  and  finish at the RING ZONE
• There will be 10 Table Tennis balls floating on the water. Among which 4 are red and 6 are yellow.
• You are allowed to pick and carry one or more balls depending upon your mechanism.
• The maximum time allotted for a trial is 7 minutes(including setup time).
• Each team will be given two trials.
• The maximum number of balls that can be put in rings that are at the water surface level (refer figure) should not exceed 5 each.
• Teams will be provided with an external 230V AC power supply.
• Teams must take care to ensure that the propulsion system and transport mechanism employed in the bot does not in any way damage the arena or splash water out of the tank.                                    

SCORING

• Points will be awarded only after the bot collects the balls, reaches the ring zone and puts the balls into the rings.
• The bot is said to have completed its task only if it puts all the balls into the rings.
• The point scoring system is based on the formula below:  

Where

n = Total number of balls passed through the rings,

n_r = number of red balls passed through the rings,

n_y = number of yellow balls passed through the rings,

t = time taken to finish the event in minutes.

BOT SPECIFICATIONS

• Bots may be wired / wireless.
• The controlling wires (if any) should not be held taut at any point of the event.
• Bot dimensions should not exceed (L*B*H) 30*30*35 cm³ with L & B making a plane parallel to water surface. Please note that a bot which fits into a box of 30x30x35 cm3 might not satisfy the above condition .The organisers’ decision in this regard will be final.
• There is no restriction on the weight of the bot.
• The potential difference between any two points on the bot should not exceed 12V.
• There is no restriction on the mechanism used to propel the bot and the mechanism used to lift, carry and throw the ball(s).
• Electrical components such as motors must be adequately insulated to prevent complications arising from coming in contact with the water.
• There is no restriction on the type of design of the bot. It is left to the participants to design their bots according to their own strengths.

ARENA SPECIFICATIONS

• The flume will be transparent on one side, and open from the top.
• The width of the flume is 0.72 m.
• The flume will be filled with water up to a depth of 0.5m.
• There are three obstructions of length 0.35m perpendicular to the wall of the flume.
• The ring zone has ring frame with 4 vertical rings located at the corners of the rhombus of diagonal 50cm.(for further details refer the figure)
• The diameter of each ring is 7cm. 
• The ring frame is symmetrical about the water level. 
• There is no restriction on the minimum distance between the bot and the rings. 
• Please refer the diagrams for further details regarding the arena.
