“I tested both LEDs and small incandescent light bulbs and although LEDs require less current to produce the same amount of light, light bulbs tend to create a softer effect. In this circuit I’ll use LEDs but nothing stops you from using light bulbs.”

“In this part we will make the sensor part. The sensors will help our robot detect obstacle in its path. The sensor system is of very basic type of infrared(IR) reflectance sensor. It is made up of an IR Transmitter and an IR receiver.”

“Well, it can grip stuff, and your robot can use it as hands! All for less than $10 using some hand-tools found around the house.”

“Our project was to build a mobile device that retreats from movement. The device recognizes and exhibits object avoidance, in order to not run into things, but does not respond unless an object is moving towards it.”

“The main aim of the project is to implement a Wireless Sensor Network (WSN) Tracking System. This system is based on a few basic ideas: Sensor Nodes knowing each other’s position — Collaboration tracking via multi-sensor nodes — Estimation of the position of the trespasser robot using Extended Kalman Filtering.”

“This is how I started the entry for the open source project that is going to be gathering the iformation about Oh_Oh the open hardware robot that MA. Student in Interaction Design Xun Yang and myself designed for the Spanish Cultural Center in Mexico City. All the work is being done at K3?s laboratory for prototyping during the first half of July.”

“D-pad is short form for directional pad which is usually a thumb-operated directional control with one button on each direction. For me, it is a very good input for a microcontroller system that allows the user to navigate through various menu and setting for a microcontroller system. ”

“This project came about when trying to make a low cost autonomous robot for use in
education. The idea being that students would be able to identify with the Xbox controller
and enjoy hacking it into something far more interesting!”

“When you don’t have time to do a real project you make up one. While doing some microcontroller tests I was using four separate LEDs. This was a bit messy with all the current limiting resistors. What would be better would be a small set of LEDs with resistors in one handy single block.”

“Hey folks, this post is about my approach to building a pretty basic dual brushless motor controller. I’m going to focus on the power section in this post, and as soon as I have time I’ll discuss the code/FroBoard side of things in another post. I got started on the power section last night after a copious amount of coffee, and wrapped it up this morning- it’s a pretty simple build if you’re used to building stuff on perf board.”
