I apologize that the videos start with the phrase “hey Jerry”; I was never expecting to release these videos to the public. This is a project I worked on for my brother and\u00a0his kids.<\/p>\n
The purpose of the project was\u00a0to create a robot that could be\u00a0driven over the internet. The approach\u00a0is pretty simple:<\/p>\n
<\/p>\n
My brother was in charge of getting the robot platform and I created the software to run it all. Here are a couple videos showing my progress. I use LEDs to show outputs changing, but the final project will actually be turning on motors to drive the robot.<\/p>\n
The first video shows a simple android app that I built to talk to an arduino board over bluetooth. I demonstrate the pairing procedure, and then show that I can turn LEDs on and off from the phone. I’m serializing data over the bluetooth connection and the arduino program (that I also wrote) parses it and change the voltage on the output wires.<\/p>\n

This next\u00a0video demonstrates the same thing working, however, the device that is sending the signals\u00a0to change the LEDs is a 2nd android phone. There is a socket connection between the two phones which allows me to send data between them. This means that the arduino board and 1st phone can be anywhere in the world, and I can still send commands to it from a 2nd android phone over the internet.<\/p>\n

With these pieces working we were able to wire the arduino up to the robot platform and drive it around! My brother lives in Massachusetts and I live in New Jersey, and I drove around his house using my android phone!<\/p>\n
Our goal was to bring video over from the android phone into the app I built as well, but I never had time to finish that piece. My brother used a video app that broadcasts the video from the phone through a web server, and this\u00a0allowed me to connect to a live video feed through my computer’s web browser while I drove the robot from my phone.<\/p>\n","protected":false},"excerpt":{"rendered":"
