Compu-Drive

Overview

Objectives/Goals Program a laptop so that it will interface with an R/C car wirelessly. Methods/Materials construct the interface. write the program (in C). Hardware: # 1x 630E Thinkpad; # 1x bread board; # 8x relays 5vdc DPDT; # 2x parallel port cables; # 1x plastic enclosure; # 1xCard board box; # 2x R/C micro tanks with radio controller (49 and 27 Mhz). Software: # Slackware Linux ; # gcc c compiler; # jed c development interface; # parapin package. Tools: # Soldering iron; # Solder sucker; # Solder ; # Pliers; # Screwdrivers ; # Duct tape; # Digital multimeter; # LEDs; # Drill; # Dremel; # Wire and strippers. Results YES i was able to do this however i came accross many things that gave me trouble such as linker errors segmentation faults null pins bios settings but with much time spent troubleshooting i was able to find the root of all theese problems to come to the conclustion i had hoped for. Conclusions/Discussion I was able to do what i had set out to do. I had constructed the interface, written the code and built a platform which two little cars drove around on, as they were programmed to, the only part to the problem that that was less than satasfying (to me at least) was the fact that i could not predict the cars path with much precision, this was because the cars speed is inconsistant, and they usally go increasingly slow as the battery dies.
