Autonomous vehicles capable of following a person, without any conscious effort by the person to guide the vehicle, have may uses in the world today. Personalized Equipment Guided Gadget (PEGG) is a prototype cart with the capability of following an individual carrying a two-way radio. The cart can follow an individual from a certain distance away while avoiding obstacles which meet certain criteria. Direction finding relies on a radio frequency horning antenna to determine the direction from which the signal originates. PEGG detects obstacles in its path by using ultrasonic sensors positioned in front, on its left, and on its right. If an obstacle is detected in front, and if there is no obstruction on the side closer to the transmitter, it veers towards that side, otherwise it turns to the opposite side. It resumes tracking once the obstacle has been bypassed. PEGG travels at approximately a speed of a foot per second, since the user is expected to travel at walking speed. Z80 assembly language was used in programming the overall control and intelligence of the system.
