MEET (BC)² (GROUP #3)

Members (from left to right): Rachel Bevill, Brae Bower, Samantha Cherbonneau, Professor Ahmadi, Anthony Contreras

• Design a robot that will move along a specific path, guided by rear wheels and front sensors

• Implement a program that codes for the forward movement of the robot along a black curved line, the execution of a U-turn at the end of the line, following the path back to the start

PROGRAM CODE FOR THE BATMOBILE

• Design, build, code, and gather data from a centrifuge

CENTRIFUGE EXPERIMENT

void main(){ int speed = 0; float separation_time=1.0; float ramp_time=0.5; while (start_button()== 0) {printf("\nPress start to begin");} while (start_button() == 1) { while(1) {sleep(3.0); printf("\n mixed value=%d", analog(6)); {motor(3,40);//ramping up sleep(2.0); motor(3,60); sleep(2.0); motor(3,80); //ramped up sleep(2.0); motor(3,100); //full speed sleep(12.0); motor(3,80); //ramping down

sleep(2.0); motor(3,60); sleep(2.0); motor(3,40); sleep(2.0); motor(3,0); sleep(9.0);} //ramped down

ao();while (1)

{sleep(3.0);printf(“\n water value=%d”, analog (6));}while (1){sleep(3.0);printf(“\n oil value=%d, analog(6));} } }}

CENTRIFUGE PROGRAM CODING

• Learned to code programs through Interactive C• Observed the importance of trial and error• Developed stronger communication skills• Discovered the importance of teamwork
