Useless Robot

Useless Robot Overview

Project by Austin Bartmess and Jeremy Deremer

This is a robot developed on an ARM Microcontroller (LPC 1768). It uses a servo, two DC motors both powered by an external power source, nine red LEDs, two RBG LEDs, a speaker, a toggle switch and a transistor.

The goal of this robot is to stay off. However, the user can turn it on without harm. It attempts to stay off via turning a toggle switch off with an arm attached to a servo. If the robot is turned on too much, it will progressively get angry. It starts by not smiling and changing eye colors. Following that, the robot will frown and yell at the user. Finally, the robot will drive around randomly while screaming and looking angry via its LEDs.
