Sound Seeking Robot

I have done several posts from the Cornell University electrical engineering senior design site. Here is a robot that follows sound. It sounds like a really cool project. It apparently has three microphones, and a microprocessor detects which microphone is receiving the strongest signal. It will then turn the robot to the microphone that hears [...]

DIY Altoids Robot

David Fowler from uchobby.com has designed a simple robot for the beginner DIYer. This robot uses no microcontroller and no difficult circuits. This simple robot will avoid obstacles and simply uses 2 switches, 2 motors, and an altoids can. It is a great weekend experiment for somebody that wants to get their hands wet in [...]

Build your own Segway Scooter

This guy actually built his own version of the 2 wheel segway scooter. It actually seemed to cost a lot of money for the components, so might not be the cheapest DIY project, but is definately cool. He uses an Atmel microcontroller to control his scooter, and uses a Gyro from a camcorder to detect [...]

Line Following Robot using Comparator

This article is from a link on one of my posts. He built a line following robot out of a plastic sandwich container, so he named it “Sandwich”. This robot is similar to my line following robot, but it does not use a microcontroller. He just used a comparator. This circuit will make a decision, [...]

DIY Line Following Robot 2

Introduction: Well, I have finally had a chance to get over all of my finals, and hopefully did well. I will find out on Monday. Well, as I have promised, here is my next DIY how to project. Beware, it is going to have to be in depth, and long. As any good engineering project [...]

Robotic Sensors

Here is a pretty simple page that gives pictures and descriptions of lots of sensors used in your own DIY robot. There is not a lot to say, except that I thought it was a useful resource, especially if you are interested in building a robot. [Link]

Underwater Submarine

This DIY was submitted by the author, and tells how to build a submarine out of pvc pipes and bilge pumps. The purpose of this device was to make a underwater camera case that evolved into a full controllable machine. This site has lots of pictures and gives some detail about how to build it. [...]

Graffiti Robot

Here is a robot car that that writes text using a row of 5 spray cans. I am not sure what it would be used for, but it is still pretty cool. It is based on the technology of a dotmatrix printer. It uses a microcontroller with a stored message, and a timer. It is [...]

Robot avoids obstacles

Here is another project from the guys at Cornell university. This is a robot that uses LED sensors to avoid objects. It is pretty cool, and it has a video. These projects are a little difficult for the casual do it yourselfer, but it is fun. It could be done without too much trouble if [...]

Robot follows black tape

Here is a website that makes a robot that will follow a line of electrical tape layed down on the floor. This is similar to one I made in undergrad. If I can find my notebook, I might put up how I did it. I do have a video of mine somewhere, also, but no [...]
