Project 704Ψ Design team: Sarah Steward Chad Harrington Kyle Levesque
2
Problem statement Design a miniature automobile 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 SAMPLE CODE /* This section of code will ~save space in memory ~ check condition of record button ~ if pressed ~ records the input in memory ~ waits 100 ms, and ~ checks if system is in same state */ byte path[1000]; void main(void) { if (y == 0x80) { path[i]=19; i++; PTT=2; } DELAY_100ms(); }
12
Play Back This section of Code will : ~read the information from array ~ send information out to the motor controller ~wait 100 ms, ~ Checks if bin is full ~Repeat process until prompted to stop.
13
Dump Bucket This section of Code will : ~ will prompt the automobile to dump out collected materials at a set location (occurs when dump bucket is full and/or when automobile reaches its end of route)
