I’ve decided to take on the project of building my own robot. I’ll be doing this in two phases. Phase 1 is simply a wheeled robot that roams around the room randomly, avoiding contact with objects. I’ll be accomplishing this with IR sensors, as well as a Parallax PING))) sensor. The PING))) sensor uses sonar to accurately determine distance, and the IR sensors use light reflection to determine distance. I’ll be using the Arduino (open source hardware!) to control all of my inputs/outputs and logic.
My motor shield kit for the Arduino showed up thanks to Adafruit Industries. This motor shield simply sits on top of the Arduino and has all the “helper circuitry” to control multiple dc motors, stepper motors, and servos easily. Assembly was very simple, and I was controlling a servo in no time. I have 90% of the parts for Phase 1 of my robot now, so I can now start build out. I’ll probably be using a wood chassis, but have not decided yet. I’m waiting for my motors and motor clamps to show up before sketching out the chassis design.
Here are some pics of the motor shield assembly.
Phase 2 will be having the robot be able to detect a human, and attack follow them. I’ll be testing my follow logic first with a color sensing sensor (follows a color), and if that goes well I’ll get a thermal sensor, so I can find humans (and animals) based on body temperature.
Ill make another post once I have more progress.
