Have you ever been enthusiastic about fabricating your own racing vehicle which demands least from your pocket but returns the best among all?? Well, TZ-17 presents you one of its most sought-after event -The Mousetrap Racer wherein the car is powered by mousetrap's spring and your skills to use physics. In simple words change of potential energy to kinetic energy is all you need to take care of. Basically if you can innovate, you can be a master. So, are you daring enough to innovate, compete and win??

PROBLEM STATEMENT:

Design, build and test a vehicle using energy of one or two snap mousetraps that can compete for different challenges of the competition.

Round 1:

(Speed test)

The vehicle has to cover maximum distance in a time span of 10 seconds. Each team will have to try 3 times, the best two trials will be considered for judgement.

Round 2:

(Accuracy test)

In this round the aim is to stop the mousetrap car closest to a specified target. The target will be 5 meters from the start line, in the center of the 2 meter wide track.

Round 3:

(Reverse technique & Power test)

In this round the vehicle’s ability to brake, reverse and its accuracy will be tested. Vehicle has to run forward for 3 meters, reverse direction automatically, and stop at the 4th meter from start line.

SPECIFICATIONS:

  • Mousetrap Base must be less than 10 cm x 20 cm.
  • Entire vehicle must fit within a 0.75 meter x 0.75 meter box.
  • Teams must bring their vehicle, any tools required to calibrate it.
  • Event Managers will provide the track, the official score sheet, and tape measures/stopwatches etc. required to test the vehicles.
  • Maximum 3 members per team.
  • Maximum 2 mousetraps are allowed.
  • The axle of mousetrap shouldn’t rotate more than 180 degree.
  • NO other energy source may be added (e.g. CO2 cartridge, battery, etc.)
  • In every round, Each Mousetrap Car will be allowed 2 trials. The BEST will be recorded in a single run.
  • The vehicle must remain in its "lane", i.e., 3 meter wide path. Any deviation from the path will result in disqualification. (For Round 1 and 3 only). For round 2, the width limit is 1 meter.
  • Distance will be measured from the tape at the starting line to the point of the vehicle that was closest to the start line at the time of release.
  • The vehicle must start and steer itself. Measurements of distance will not measure the total distance travelled, only the displacement distance.
  • Surface will be little rough (Wooden etc.).
  • All parts of the vehicle must move as whole. No anchors, tie downs, launching ramps are allowed.
  • One team can use only one mousetrap car. They will not be allowed to change their mousetrap car in the event.
  • Decisions taken by judges will be final.

 

JUDGING CRITERTIA:

ROUND 1:

Best of three trials will be considered.

Top 30% of teams will be shortlisted for second round.

 ROUND 2:

The winning car will be the one that stops closest to the specified target. Points would be awarded accordingly.

 

ROUND 3:

Accuracy and time, both will be taken into account with a weightage of 60 % and 40 % respectively, for final judgment.

Formula for final score = 100-{(D*0.6) + (T*0.4)}, where D= total distance error in centimeters and T = Total time span in seconds.

The stand still (final) position of vehicle will be considered. Braking technique plays a role here.

Q1: WHAT IS A MOUSE TRAP CAR AND HOW DOES IT WORK?

A: A mouse trap powered racer is a vehicle that is powered by energy of a wound-up mousetraps spring. Most basic design is to tie one end of string to the tip of a mousetrap’s snapper arm and other end is wound to axle driving the vehicle. As the mousetrap spring decompresses, it rotates the axle of vehicle and drives it.

Q2: WHAT KIND OF THINGS WE SHOULD KEEP IN MIND WHILE DESIGNING A CAR?

A: Based on requirements of each event, Car can be designed. Things to keep in mind while designing- Weight to axle ratio, length of arm, friction, wheels selection, Base material (light and tough like aluminium rims, hard plastic etc.)

Q3: HOW DO I REGISTER?
