Single Chip Microcontroller
Brian Sanders & Dan McHugh
Advisor: Dr. V. Prasad
This project design uses a single chip (MC68HC11A8) to control various
motions of a cylindrical robot arm. The 68HC11 translates a three byte
code, sent from a Turbo C program into control information. This information
controls a grasping motion, a vertical motion, and a rotary motion. The
68HC11 controls a stepper motor, PWM to two D.C. motors, and receives feedback
from encoders to determine velocity and position of the arm and limit switches
that indicate when the limit of the field is reached. The 68HC11 also sends
feedback to be displayed graphically on the monitor.
