An Advanced Line Following Robot With PID control

Posted April 10, 2013 by Chris

“This tutorial details the process of building a line following robot. The robot can follow both black and white lines. It uses a sensor array to sense the line and a PID control to follow the line.”

Urban Tapestries – Feral Robot Client Architecture

Posted April 2, 2013 by Chris

“This report provides technical documentation for a prototype mobile environmental sensor that integrates with the Urban Tapestries public authoring system — the Feral Robot, version 2. Descriptions of the main requirements, as well as the steps in the hardware/software platform development are presented.”

Ultrasonic Security System

Posted March 26, 2013 by Chris

“We were inspired to build an ultrasonic security system for our final project by our housing situation this summer. Security is an important part of home, especially if we are going to share a house with prior strangers without a lock on our room door…..In case of intruders, it sends off a sound alarm and alerts the owner via email..”

A Sensitive DIY Ultrasonic Range Sensor

Posted March 13, 2013 by Chris

“I needed some ultrasonic range finders for my project. But most of the commercial sensors like Parallax’s PING sensor and other similar products are quite expensive, especially if multiple units are needed. So I thought why not building it myself?”

Simple Informatics Black Box

Posted March 6, 2013 by Chris

“Our project was, to put it simply, a personal informatics black box that you clip onto your belt. As you go about your day your activity, surrounding environment and locations are tracked to produce a report telling you how much time you spent inside and outside. The device leverages off of a system-of-systems providing context-aware analysis for such ubiquitous computing devices.”

Haptic Data Visualizer

Posted March 3, 2013 by Chris

“The goal of our project was to create both the hardware and software platform that can be used as a adaptable haptic data visualization device. Imagine you have a complex data set from which you create a surface plot in MATLAB….what if you could feel it? Bring it to life? With our current haptic visualizer, users can feel any arbitrary surface plot generated in MATLAB…”

Connecting A Barcode Scanner To An Arduino

Posted February 25, 2013 by Chris

“A gadget that I demonstrate today is a portable autonomous barcode scanner built using an Arduino board, USB Host shield, handheld USB barcode scanner and LCD display. The operation is simple – when handheld scanner button is pressed, it scans the barcode and sends it to the Arduino symbol by symbol. The Arduino then outputs these symbols on LCD display.”

Instrumented Steering Wheel Project Demo

Posted February 24, 2013 by Chris

“This project seeks to develop an additional form of authentication for vehicle security, specifically in the form of a tapped password. The goal of this project is to implement this form of authentication and determine the level of possible security while maintaining enough flexibility to allow human variation in password inputs.”

Bluetooth Wireless Bathroom Scale

Posted February 23, 2013 by Chris

“Start with a cheap bathroom scale from ikea, then strip out all the hardware except for the load cells. Add in the following: a microcontroller, roving networks bluetooth serial module, 24 bit ADC, 4 AA batteries, a linear regulator and input ORing diodes.”

MC40SE – Controller for Line Following Robot

Posted February 13, 2013 by Chris

“Last month I talk about Remote Controlled Mobile Robot using MC40SE, this month I want to use it for simple line following robot…The list of hardware needed: MC40SE board, LINIX Brushless Motor, 2 x 4” Nylon wheel, 2 x 12V battery, 4 x fiber optic sensor and a robot base which mounts with a castor and brushless motor properly.”
