New Project: Build a Two-Octave Laser Harp

I find laser harps fascinating. The first time I saw one was when I stumbled across a video of a guy using using lasers to play the theme song to Tetris. I thought it was the coolest thing ever, but I couldn’t justify the cost of buying one. Instead, I decided […]

Robot can barely move with so much hardware strapped to it

We think that [Andrej Škraba] needs to start looking for a beefier motor platform. This little robot has so much hardware strapped to it the motors can barely keep up. But with a little help it can make its way around the house, and it takes a whole lot of connectivity and computing power along for the ride.

The white stick on the top is a single-board computer. The MK802 Mini sports an A10 processor and up to a gig of ram. Just below that is a USB hub which is sitting on top of a USB battery pack. This powers the computer and gives him the ability to plug in more than one USB device. The robot chassis is from Pololu. It uses an Arduino and a motor shield for locomotion, with commands pushed to it via USB.

This setup makes programming very easy. Here [Andrej] has a keyboard and HDMI monitor plugged in to do a little work. When not coding it can be disconnected and driven over the network. He makes this happen using an Apache server on the MK802 and node.js. See a demo of the system in the clip after the break.

Arduino Motor Shield Help!!!

I just got my first Arduino motor shield. However, all the servo ports have 4 pins. The problem is that my servos only have 3 pins. Any help is greatly appreciated! By the way, my shield is an Arduino Motor shield from Seeed.

Very Simple Robot

What does it do?

Can take simple Forward, backwards, stop commands.

My robot is a hacked RC car controled by an Arduino Duemilanove.   It has no sensors,  but I have left room on my chasis so I can add some more later when I feel more comfortable around Arduino.  Most of the time on this project was spent dealing with Arduino code and the motor shield.
