1. Project 704Ψ Design team: Sarah Steward Chad Harrington Kyle Levesque

2. Problem statement Modify a miniature vehicle that will… Be able to travel through any hallway Collect paper & magazines from bins Drive to a set location and unload material Automobile will not need human aid, after a initial button is pressed.

3. Solutions Teaching the automobile the correct path – By recording a directed path in memory of an HC12 micro controller and then playing back the path, when the playback button is activated. Drop bins – Sliding material out of the bins, and into a dump bucket on top of the automobile. Simple dump truck style unloading - Using a motorized lifting system to slid material into the unloading area.

Record /* * Function record * This function will record the input from the joystick to memory * */ void record(void) { int i; i=0; asm_main(); // call the assembly function for(;;) { DELAY_100ms(); path [i]= (PTAD & 0x0F); if (i == 500) { path[i]=0x00; // stores all zeros to memory break; //breaks out after 50 seconds of looping } i++; } // waits until the switch button is neutral DUMPROUTINE();

18. Play Back /* * Function playback * This function will playback the information recorded in memory * */ void playback(void) { int i; i=0; // call the assembly function // allows us to write to the whole port T DDRAD = 0x0F; RDRAD = 0x0F; for(;;) { if (path[i] == 0x00) break;//checks to see if byte is all zeros if so exits out PTAD = path[i]; // stores memory location in port T i++; DELAY_100ms() ; // waits 100ms } DUMPROUTINE(); DDRAD = 0; //add to wait until switch is recentered return; }
