R2-D2 is coming along nicely! It’s a joint project between my sister and I, but she doesn’t know much about coding and hasn’t signed up for Stardance, so it’s all on my account. The chassis of the robot is from a kit we had when we were in elementary school, but support for the original app was discontinued a few years ago. We’re reviving it with an Arduino Uno, the original motor (which is fixed to the internal frame and wheels), a replacement servo motor to steer the robot, an IR receiver so it can be remote controlled, some LEDs and a buzzer. I found an R2-D2 sound generator for Arduino that I tested and it sounds just like the droid. We’ve divided the project into a few phases: First, get the remote control working with the internal frame and have a functional (if ugly) little robot. Then, make it possible for R2 to roll around on his own with an ultrasonic sensor to navigate. After getting both modes working, we’ll put the internal and external frames together, which will involve a lot of problem-solving. We’ll ship the project after each phase, mainly to keep it organized. So far, we are well on our way through phase 1. I’ve put all the components on the internal frame and written a test sketch for them. My sister also put the decals that came with the kit on the external frame. The next step is to log the remote control values and have R2 know what to do when he receives the values.
