1. OBJECTIVE
Underwater vehicles are vital to port & harbour security, naval and scientific exploration,
underwater cleaning etc. This fun-filled and challenging competition aims to introduce students to
this fascinating world so that they can explore career opportunities in this field. The competition
will spur interest and promote education in this area and motivate young and aspiring engineers
and scientists to further pursue this field.
2. BRIEF DESCRIPTION OF MISSION
2.1 The team of contestants have to design and build a remote operative vehicle (ROV) or an
autonomous underwater vehicle (AUV). ROV and AUV are separate categories.
2.2 The mission involves the picking up of as many objects (cargoes, one at a time) from the
middle section of the tank and dropping them in baskets at either ends of the tank. At
the end of each run the number of objects in each basket ideally should be equal. For
both ROV and AUV, each pair (one in each basket) gets four (4) points and remaining
unpaired objects in the basket get one point each. For AUV’s, they shall be awarded
double the points for ROV’s, as well as a bonus of two (2) points on condition that the
robot(s) deliver(s) at least one (1) object into the basket.
2.3 While doing so they would have to maneuver through window frames which will be non
magnetic on either sides of the tank.
3. TANK SPECIFICATIONS
3.1 The game will be played in an L-shaped tank of dimension: 1425mm x 1425mm x
500mm. The tank has a glass of 12.5 mm thickness. See Figure 1 for details.
3.2 There shall be two rectangular window frames, 30mm thickness, and one on each
section of the tank 500mm from the ends of the tank. See Figure 2 for detailed
dimensions.
3.3 The centre section of the tank will have a bump which is 12.5mm in height.
3.4 In the central area of the tank there shall be a cargo holder containing 16 objects
arranged in a grid. This holder will be elevated from the tank floor by about 2 cm.
See Figure 1 layout.
3.5 The cargo holder will be a square of 100mm sides with the sixteen objects arranged
in a grid. The cargo holder will be made from a non-magnetic material. See Figure 3.
3.6 The cargo to be lifted will be marbles in the case of ROV and nuts for AUV as shown
in Figure 4. The marbles are ceramic in nature and will have a diameter of around
15-17mm weighing 3 to 7g each. The nuts will be ferromagnetic and weigh between
10g to 20g.
3.7 A black tape, 4 to 5cm wide, will run through the centre of the tank and on both
sides of the tank at a height of 20cm from the bottom.
3.8 There are two basket areas at both ends of the tank. There will be a barrier of about
2cm in height separating the basket from the rest of the tank.
3.9 The water depth in the tank will be 40 cm and flush with the top of the rectangular
window frames mentioned in 3.2 above.
