Lab 01: Introduction & Brainstorming

This lab is an introduction to the AEV. The codes used in the lab are provided as shown in the deliverables below.

Progress Report Questions:

The propeller begins to rotate at a low speed. It then started to rotate, then stopped and delayed to start up again. Its response throughout the rest of the program seemed to be delayed.

Deliverables:

Arduino Codes for Lab 1:

acelerate(1,20,45,2);
- Accelerate motor 1 from
  20% to 45% power in a time of 2
  seconds
motorSpeed(2,16);
- Set motor 2 speed to 16%
  power
goFor(5);
- Runs both motors for 5 seconds
brake(4);
- Brakes all motors
reverse(1);
- Reverses polarity of motor 1
motorSpeed(4,20);
goToRelativePosition(30);
- Sets all motots to 20%
  power, and will continue
  to run them at 20% power until the
  AEV moves 30 marks from
  its current position
motorSpeed(4,20);
goToAbsolutePosition(300);
- All motors are set to 20%
  power, and will continue
  to run at 20% power until the
  AEV moves 300 marks from
  its starting position

Arduino function calls:

Function Call	Function	Example
celerate(m,p1,p2,t);	Accelerates or decelerates motor(s) m from start speed (%) p1 to end speed (%) p2 over a duration of t seconds	celerate(1,20,45,2); Accelerates motor 1 from 20% to 45% power in 2 seconds
motorSpeed(m,p);	Initializes motor(s) m at percent power p	motorSpeed(2,16); Sets motor 2 speed to 16% power
goFor(t);	Runs the motor(s) at their initialized state for t seconds	goFor(5); Runs the motor(s) at their initialized state for 5 seconds
brake(m);	Brakes motor(s) m. Note: This does NOT brake the AEV, just stops the motors from spinning	brake(4); Cuts the power to all motors
reverse(m);	Reverses the polarity of motor(s) m	reverse(1); Reverses polarity of motor 1
goToRelativePosition(n);	Continues the previous command for n marks from the vehicle’s current position. n can be positive or negative, with positive meaning the vehicle is moving forward, negative meaning the vehicle is moving backward	motorSpeed(4,20); goToRelativePosition(30); All motors are set to 20% power, and they will continue to run at 20% power until the AEV reaches 30 marks from its current position
goToAbsolutePosition(n);	Continues the previous command for n marks relative to the overall starting position of the AEV	motorSpeed(4,20); goToAbsolutePosition(300); All motors are set to 20% power, and they will continue to run at 20% power until the AEV reaches 300 marks from its starting position
