SOLAR REGATTA

 “Every 24 hours, enough sunlight touches the Earth to provide the energy for the entire planet for 24 years.

 The SOLAR REGATTA competition for 8th graders is not only of play and excitement, but also great way of learning some basics in science. This event and its Learning materials explain the hidden science in very simple and practical way.

The competitors are expected to build a SOLAR BOAT out of any materials of their choice, and sail off to win the race.

 

SOLAR REGATTA RULES 2019-20

 

PROBLEM STATEMENT-

Build a boat that works on solar energy and complete the 4 meter run in shortest possible time.

IMPORTANT-

STUDENTS SHOULD BUILD THEIR BOATS AND NOT USE READY MADE/ BOUGHT OUT BOATS

HULL OF THE BOAT MUST BE HANDMADE.

READY MADE PROPELLER AND SOLAR PANELS ARE ALLOWED FOR THIS COMPETITION.

 

Notes-

  1. The boat should be powered by solar energy only.
  2. The boat can be made up of any materials of competitor’s choice OR from the kit available with cognium’s website.
  3. Such modified or rebuilt boats must also meet the dimension and other rules as for the first round.
  4. Competitors may buy a solar boat kit from our website if they wish. they may use it for purposes of trials experiments practice or for competing. However buying kits from our website is optional and is made available for competitor’s convenience only. buying from Cognium will not earn any extra credits at the competition.
  5. competitor shall ensure that parts bought from sources other than Cognium, conforms the rules of the competition, failing which the model will be disqualified
  6. There will be a revised problem statement for the final round. These revisions will be announced after completion of first round. Winners of the first round will, if they feel necessary, modify or rebuild their boats to meet the revised problem statement.

 

RACE DESCRIPTION

The tank/ arena is placed in open, under the sun or it can also be placed indoors (during monsoon) in which case, suitable electric lamps will be placed on tank. The solar panels will generate electrical power due to sunlight or electric lights, to run the solar boats. Before  the start of race, all boats are placed behind the start line. A black colored card board will be placed over the solar panels before start of each race. At the end of countdown , the black cardboard will be removed, allowing the light fall on the panels. Due to charge produced by the panels, motors start running and the boats start racing to the finish line. Time taken by each of the model to reach the finish line will be recorded. Model completing the run in shortest period of time will be declared as winner.

RULES

1) Dimension rules

  1. The overall length of the Boat shall not exceed 175 mm.
  2. The overall width (including any extensions) on the sides of boat shall not exceed 100 mm.
  3. The boat must fit in box (l)175mm x (w)100mm x (h)125mm.
  4. The boat must have 1 propeller only.
  5. Maximum outside diameter of propeller must be 40mm.

 

2) Weight rules

  1. There is no limit on the weight of the boat.

3) Materials of construction.

  1. It is student’s choice to select any material or design, so that it complies with the rules of competition and floats, completes the race.

4) Power rules

  1. The motor must receive power only and directly from the solar panel. Any kind of electric charge storage devices/circuits/ switches etc are not permitted to be connected.
  2. Solar panel should be of 6v 250 ma rating or area of panel should not exceed 10000 sq. mm
  3. Potential from solar panel should not exceed 6 v.** (see below “how to test the output of solar panel”)
  4. Light reflectors may be used. Provided they do not violate the dimension rules

 

PROHIBITED ITEMS  (which cannot be used)

Boat can be built out of any material desired by the competitor, but readymade boats are not permitted

 

  • No part of the boat shall be expanded during the run. I.e. The dimension rules must be followed during the entire run of the boat.
  • Starting devices, magnets, springs devices that alter the power from solar panel, propellants, or propulsion systems
  • Wet paint, or sticky substances
  • Glass or excessively fragile parts
  • Electronic, electrical power storage devices or lighting devices
  • any parts attached to any device on boat that mechanically alters rotation of propeller.

 

OTHER RULES

  1. First inspection of boat will be ‘self inspection’ by the competitor. He shall complete and submit the self inspection form on or before the specified date.
  2. A boat will be disqualified if found not conforming the dimensions or has prohibited parts, or does not conform to information submitted in self inspection form.
  3. Each boat may be re-inspected at the competition venue and must pass inspection before it will be allowed to compete.
  4. There will be a re-inspection of the boat before run of the second round.
  5. Once a boat passes inspection and is entered into the race, no alterations are permitted.
  6. The inspection committee has the responsibility to disqualify those boats that do not meet these rules.
  7. If a boat suffers a mechanical problem during a race participant will have up to five minutes to fix the boat. Only fine tuning of boat is allowed, alteration is not allowed.
  8. If the boat cannot be repaired in 5 minutes, defective boat will be allotted another slot to run the race, before which the boat must pass re-inspection test.
  9. Electronic stop watch will record finishing place for all boats in each race. In the event of
    1. Technical difficulties, the Finish Line Judges will determine the order of finish. They may use video recording at the finish line
    2. All decisions of the Official Race Committee  are
  10. Only Track Officials and competitors will be permitted in the track area.
  11. No kind of reflectors which are not part of the boat is permitted to shine on the boat panels (reflectors which are not on board, and made to shine and increase the solar panel output is not permitted)

 

ARENA-TANK-

  1. HEIGHT OF THE TANK- 15 CMS
  2. DEPTH OF WATER – 12 CMS
  3. LENGTH OF THE RUN- 400 CMS

 

 

 

HOW TO TEST THE SOLAR PANEL SPECIFICATIONS

To measure open circuit voltage, Volts (Voc):

Disconnect the solar panel completely from any connected components

  • Angle the solar panel towards the sun with clear skies (between 11 am to 1 pm)
  • Ensure that the multimeter is set to measure Volts
  • Measure the voltage between the +ve and -ve terminals by connecting the negative contact from the voltmeter to the negative on the panel and the positive contact on the voltmeter to the positive on the panel.
  • reading should not exceed  6 V (tolerance  of 0.5v +/- allowed)

 

To measure short circuit current, Amps (Isc):

Disconnect the solar panel completely from any connected components

  • Angle the solar panel towards the sun.
  • Ensure that the multimeter is set at 10A. (you can change the setting to lower A range later if required)
  • Measure the current by connecting the +ve lead on the voltmeter to the +ve on the panel and the -ve from the voltmeter to the -ve on the panel
  • reading should not exceed max 0.1 amp (100ma)
