I didn’t feel so happy with this minimalistic chassis design so I felt the need to add some complexity to it. And because I am a 3D lover and because I have some spare time I decided to do what I never use to do: “think before act”. Oh, and the other thing that makes [...]
BOTtle is a robot like many others but with a particularity, the wheels are made of plastic bottles as you can see in this video: The components I will be using: The servos are already attached to one another with double side-tape, I will show you how to attach the wheels to the servo horns [...]
The motoruino is so easy to setup, just plug the motors, sensors, upload code and your bot is ready to go. I added a big capacitor (4700uF) on the PCB power connections as I had the Motoruino resetting randomly when a motor started (OddBot explains everything here) This is a quick test drive with the [...]
Motoruino page: www.guibot.pt/motoruino It´s since I started with robotics, that I felt the need of having a board where I could directly plug-in my motors, servos, sensors and all the stuff without having to purchase extra shields, or building pcb’s and soldering and troubleshooting and hours and hours of hard labour.. so, I decided to [...]
Two more infrared sensors were added on the front, this way he’s more sensitive to the environment. Video is on the go.. You can see more details about the construction process on this post. Updated version here. source code
This creature roams through the surrounding environment and seeks for light sources. When an object is too close it reverses motion and turns around, and then goes on seeking light. I used an old toy motor and platform, then added two LDR light sensors, a SHARP infrared sensor on the front and Arduino Diecimila for [...]
With a better understanding of robot building and navigation programming I came up with this robot! I think that the great improvement here was that I’ve made a plan of what I wanted to build and looked after solutions before the assemble process. So, this one came out a more successful robot!! This is my [...]
Here goes my second robot. This turns out to be the 4th robot actually :) I found this offroad car in an old junk and it was love at first sight! Now I want to add some brains and sensors and give him a new life :] The steering DCmotor burned out and I’ve removed [...]
