Performance Test 2

 

Introduction

Team R tried to use the one motor design that they used in Performance Test 1 for Performance Test 2, but the one motor design was unable to produce enough power to move the AEV and caboose.  In sight of this, the group decided to use their two motor design for Performance Test 2 to have another motor producing power to be able to move the AEV and caboose.

 

Performance Test 2 with Two Motor Design:

 

Code Used for Performance Test 2 with the Two Motor Design:

//AEV to gate

reverse(2);
celerate(2,0,58,1);
motorSpeed(2,58);
goToAbsolutePosition(135);
brake(2);
reverse(2);
goToAbsolutePosition(268);

//AEV braking at gate
int direction1 = getVehicleDirection();
while(direction1 == 1){
motorSpeed(2,43);
direction1 = getVehicleDirection();
}
brake(2);

//AEV stopped at gate

goFor(7);

//AEV to Caboose

reverse(2);
motorSpeed(2,55);
goFor(2);
brake(2);

//AEV at Caboose

goFor(10);

//AEV to gate with caboose

reverse(4);
motorSpeed(4,58);
goFor(2);

 

Conclusion

The two motor design used 65 J of energy to complete Performance Test 2 in 30 seconds.  The use of two motors when the AEV carries the caboose from the loading zone to the gate uses twice as much energy as when the AEV runs with only one motor, and because of this, Team R plans to improve their one motor design to be able to carry the caboose in order to save energy in the Final Performance Test.
