CRUISE CONTROL:
Problem Statement:
Design, fabricate and fly a wireless remote controlled aircraft (using electric motors only), which has all three degrees of freedom including yaw, pitch and roll and that can complete a specified task.
Rules and Regulations:
RC Plane Designing o Model Specifications:
An aircraft is defined as an object that has the four forces of flight, namely lift, drag, weight (gravity) and thrust due to propeller acting on it at any point of time.
The Aero model should have a wing span of at least 80 cm.
The Aero model must weigh less than 800 g. The model must be hand launched. Use of landing
gear is prohibited. The aero model must be hand-made. For
information on design you are advised to visit http://students.iitk.ac.in/aeromodelling.
A team can use only one model throughout the competition. The same model should be used in all
the rounds. In case of any damage, small modifications are allowed.
Only electrical motors are allowed. The potential difference, between any two points on
the machine, must be lower than or equal to 12.6V at any point of time during the competition.
The participants are free to use the materials of their choice. However the use of Balsa wood or foam (sun board) or sun pack (coroplast) or thermocole is advisable. Foam is light, easy to handle and fabricate the aircraft making it the best choice.
Participants can use Design-Foil software to design the aircraft wing.
Participants must make all parts of the aircraft themselves. Usage of Ready-to-Fly (RTF) and Almost-Ready-to-Fly (ARF) kits is strictly prohibited. Use of readymade actuators/motors, remote controls and propellers is allowed.
Use of gyroscopes (gyros) is prohibited. If anyone is found not following above rules, they
will be disqualified. Use of CF rods allowed for strengthening.
o Judging Criteria: Designing of an aircraft is a very important part of
this competition. The flight tasks in competition include aerobatics, good controls and speed. So your aircraft should be such that it can perform the given tasks effectively. The tasks for the competition are:
1. Take off and safe landing. 2. Flying as fast as you can in addition to taking
sharp turns to complete the run in minimum possible time.
Each entry will be judged before the start of the task. The judging will be based on the following criteria:
3. Functionality of Design. 4. Innovation of Design.
Proper drawings with dimensions, of the airplane will have to be produced before starting work on the plane. This will carry points under D&F.
Design and fabrication (D&F) points : 20
RC Flying
Round 1: Basics
In a given time of 3 minutes the participant has to complete at 3 square circuit and 2 circuits in the figure of 8.
Additional 1 minute will be given for safe landing.
n = number of square circuits, m = number of circuits in the figure of 8
Points:
Total points = n*2 + m*3 + 3(for safe landing)
Round 2: Spot landing
The participant will have to take off and land the plane in a specific zone. Two attempts of 1 minute duration will be given to each team.
Points:
Zone A 10 pts
Zone B 6 pts
Zone C 4 pts
Elsewhere 2 pts
Unsafe landing -5 point
Points = sum of scores of first and second attempt.
Minimum possible score = 0
Round 3: Pylon Racing
In a given time of 3 minutes (including takeoff ), the aero model will have to complete maximum number of laps between two given checkpoints 75 metres apart. Additional 1 minute will be given to land the plane safely.
N = number of complete laps, Nmin = min no of laps, Nmax = maximum number of laps
Points:
Total points = 5 + 15[(N - Nmin)/(Nmax - Nmin)] + 5(for safe landing)
Round 4: Limbo
In given maximum time of 4 minutes (including take off) the aeromodel will have to pass under a horizontal ribbon tied at a height of 3 meters. The aero model will have two pass under the ribbon 3
times in minimum possible time.
Tmax = Maximum time
Tmin = Minimum time
T = Time taken to complete 3 passes
Points:
Total points = 5 +10*[(Tmax-T)/(Tmax-Tmin)] + 5 (for safe landing.)
*safe landing: Landing in which no part of plane is damaged or detached.
Team Specifications:
Each pool should come up with a maximum of 1 RC plane.
Scoring:
Round 1 : 15 points.
Round 2 : 20 points.
Round 3 : 25 points.
Round 4 : 20 points.
Total= D&F+Round1+R2+R3+R4=100 points

at a given pressure, in another round land at predefined spots. Also
design and fabricate another water rocket that has a maximum
time of flight.
Rules and Regulations:
Plastic bottles of 1.5ltr – 2ltr can be used for the main body.
Metal sheets in any form cannot be used.
Models should be handmade, readymade rockets will not be
accepted.
Your model can be of any size or shape and can be made of
any material. But, it should not damage the arena or hurt any
person. If your model is found dangerous, you will not be
allowed to participate in the event.
The water rocket may contain any of the following mechanisms suitable for different rounds:
Gliding (wings type) mechanism Booster mechanism: in this case, participants should ensure that
they have proper launchers supporting the launching mechanism Any other innovative mechanism will be encouraged provided that
the material and mechanism used is not harmful or dangerous to any person in the field. In this case the decision of the panel of coordinators will be final and no queries will be entertained in this regard However, it is upon the team to choose what model to use for rounds 1, 2 and 3 according to the mentioned rules.
Team Specifications:
A team can consist of a maximum of 3 members for Round 1,
Round 2 and Round 3. The same team will be performing in
all rounds. Change of team for Round 1 & Round 2 is not
allowed. Teams can make different water rockets for Round 3.
For Round 1 and 2, a maximum of 10 teams are allowed from
each pool.
Arena:
The Launch Zone for all three rounds will be a circle of 1 m
diameter. Arena for Round 2 will be 3 concentric circles with their
centre at a distance of 50 m from the launch zone centre.
Region A – Circle of radius 2 m. Region B – Ring of inner radius 2 m and outer radius 4 m with same centre as circle A. Region C – Ring of inner radius 4 m and outer radius 6 m with same centre as circle A.
There is no specific arena for Round 1 and Round 3, depending on
the nature of their event.
Event Structure:
Round 1 - Range The water rocket has to be launched from launch pad and will be tested for maximum horizontal range.
Round 2- Spot Landing A specific range of the water rocket will be tested in this round. The rocket has to hit a provided target range marked on the ground as concentric circles. The center of the circles lies at a distance of 50 m from the launch point.
Round 3 - Endurance (Time of flight) The water rocket can be launched from launch pad with any suitable angle as per your convenience and would be tested for maximum time of flight. This rocket can contain mechanical components.
Scoring Criteria:
Point Distribution for Round 1:
Each team will be given a maximum of two trials. Best of the two
trials will be considered as follows. The distance covered in meters
will be directly equal to the points you score in this round. This
score will be called “A”.
Point Distribution for Round 2:
The concentric circles will carry the following points:
Region A: 100 points
Region B: 70 points
Region C: 50 points
Anywhere out of the given three circles: 0 points
Each team will be given 2 trials. Best of the 2 trials will be
considered. This score will be called “B”.
Point Distribution for Round 3:
Each team shall be given 2 trials. Best of the two trials will be
considered final. Points scored will be directly equal to the time of
flight in this round. This score shall be called “C”.

HOVERUGBY:
Ever fascinated by the wrestling giants competing against each
another for honour, pride and glory! And the speed of a rugby player
to achieve his aim. If so, then this is the event for you. Here it will be
your hovercraft that will do the talking. So get up, design the most
efficient quick wrestling hovercraft that you have ever imagined!!!
Problem Statement:
Each pool has to design and fabricate 2 hovercrafts that are light-
weight, easily manoeuvrable, quick and strong. They must out-
throw their opponent in a match of hovercraft rugby. Also they
must enter the goal area to score points.
Rules and Regulations:
A hovercraft is a vehicle which floats on a cushion of high
pressurized air and propels itself on this air-cushion using a
thrust producing mechanism. Control is generally achieved by
the use of rudders, though it is not the only solution.
The overall hovercraft dimensions must not exceed
50cmX50cmX50cm.
The model can be fabricated using foam, wood, coroplast or
any other material with permission from the coordinators.
Participants must make all parts of the craft themselves. Usage of readymade kits is strictly prohibited. Use of
readymade actuators/motors, remote controls and propellers is allowed.
The use of IC engines is prohibited. Only electrical motors are allowed.
A team has to use 2 models at a time throughout the competition. However, spare models can be fabricated, if material permits. In case of any damage to the craft, small modifications are allowed.
The potential difference between any two points on the hovercraft must not exceed 12V.
If anyone is found not following above rules, they will be disqualified.
Arena: The overall arena is an elevated surface, with 2 inclines at the goal areas. The “pitch” for the event will be as given below in 2 views:
The black shaded areas are the “Goal Areas.” The overall brown board is the pitch. Event Structure:
Each match between two opponents will contain three sets of 3 min time duration each.
Each team will play matches against every other team, thereby producing the overall result.
Your craft has to enter the opponent’s goal area and slide down the incline to the OAT stage surface to score 1 goal.
Both the crafts can also attack at the same time.
A maximum of 1 craft of the defending team can remain in the goal area at any time.
The incline will be present only at the goal areas.
Score for each craft will be summarized separately, then added with its partner to give the total score for a team in that set.
Match Rules:
Craft falling from the edge (other than the incline) will lead to -1 score.
A set will not stop until the 3 min duration, irrespective of how many goals are scored or how many times the crafts fall.
Once the attacking craft scores a goal and lands on the OAT surface, it has to restart from its home goal area.
If the defender falls from the incline and can come up without any manual interference (touching, etc.) no points will be deducted. If manually it is put onto the arena, 1 point will be
deducted for that hovercraft.
If a craft falls from the edge, it has to be manually put back onto the pitch from that boundary position.
Each successful goal will lead to a +10 for that particular craft.
Activities allowed: Hitting the other craft Dragging the other craft to the edge Any other thing you may imagine!!!
Using any kind of fire, spray, liquid or any other activity that may cause serious damage to the arena or the electronics (as per coordinators discretion) is not allowed.
Components:
Below are the components that will be provided to each pool. Apart from these, each pool is authorized to purchase any other materials required at
the expense of their respective pool budgets, on proper verification of bills by us. The materials provided to you include:
4 electric motors
Two 9gm servos 4 propellers 4 ESC
One 2mm coroplast sheet Batteries, receiver & transmitter will be provided during practice slots only.
Regularly check the website for any changes in the rules.
