The Lawnbot4000

Posted May 21, 2017 by Chris

"The Lawnbot400 is a remotely controlled lawnmower that I built several years ago to mow my lawn. It is basically a push lawnmower attached to a large remotely controlled frame."

Robotic Arm Tracks Hand Movement

Posted May 18, 2017 by Chris

"This past week, I made a robotic arm that tracks your hand in free space using a Leap Motion, Arduino, and node.js. It tracks my hand very well. It is able to pick up stuff and set it down with relatively good precision, although there is definitely some room for improvement."

A DIY Robotic ARM

Posted May 15, 2017 by Chris

"The CHORG project consists in both a hardware and software platform both of them developed by myself. The main purpose of this project is to create a robot arm capable of adapting a task to randomness of the real environment."

DIY Drink Mixing Robot

Posted May 3, 2017 by Chris

"I built a robot that mixes drinks named Bar Mixvah. It utilizes an Arduino microcontroller switching a series of pumps via transistors on the physical layer, and the MEAN stack (MongoDB, Express.js, Angular.js, Node.js) and jQuery for the frontend and backend."

The Seg Bot

Posted April 18, 2017 by Chris

"The Seg-bot is a DIY segway clone that costs around $500 to build. It will attempt to keep the rider upright at 0 degrees (level), so if you lean forward it will travel forward to correct its position – the farther you lean, the faster it will go to correct itself."

Robotic Motion Controller

Posted April 9, 2017 by Chris

"The Five-Axis Robotic Motion Controller aims to bring physical input and output closer together through the design purpose-built tools for fabrication, which hopefully leads to many new creative opportunities for designers."

Twixbot

Posted March 13, 2017 by Chris

"A metal tin makes a neat little enclosure for some electronics and is usually rigid enough to mount some motors to. I have lots of motors laying around so it took very little effort to get this particular bot running (under an hour from start to finish) and there are very few parts."

Build Raspberry Pi Robots (For Beginners)

Posted April 3, 2016 by Chris

"If you are a beginner to Raspberry Pi and were looking for a simple hardware project, then look no further. This tutorial will show you to develop a python based robot which avoids obstacles and navigates freely. Obstacle avoiding robots are fairly common and easy to make. Here, you can use this project to add object avoidance functionality to your robot."

38mm x 38mm Laser Engraver Build Using CD-RW on ATmega328p

Posted October 24, 2015 by Chris

"To build this tool I’ve used two old CD-ROM writer that lays around in my garage. The X/Y positioning system it is build using the CD-ROM motor assembly. For the engraving laser i use the CD-ROM writer laser. With this hardware the engraving area are will be almost 38mm x 38mm."

DIY – gForce 1.0

Posted September 23, 2015 by Chris

"Basically, the system uses an accelerometer to measure g-force and a SD card to store the data. An Arduino UNO is used to process the data coming from the accelerometer and save it on to a SD card. The system was originally developed for setup tuning and performance optimization in RC cars."
