The Rapid Pace Of Artificial Intelligence

Trying To Keep Up! In January 2016 Europe’s reigning GO champion, Fan Hui was defeated by Deep Mind’s AlphaGo program. Based on strategy and intuitive thinking, each move of the black or white stones of the 2500-year-old game of GO leads to a possible 250 moves. Every …

The Worker Robots

Will robots take over the world? How many times have you heard this? From magazines to books, whenever we talk about robots this notion pops up. True- when Martin Ford titled his book, Rise of the Robots: Technology and the Threat of a Jobless Future, he might have expected this kind of hyperbole, but Ford had something entirely different on his mind.

Arduino Autonomous Upgrade Module for MINDS-i 4×4 Robot 3-in-1 Kit

In the last issue of Robot, on our letters page, we introduced the MINDS-i Arduino-powered Autonomous Upgrade Module, which is a tray-like module that you easily attach to the popular 4x4 Robot 3-in-1 base kit chassis. The standard 4x4 Robot Kit enables you to build one of three configurations, including leaf spring, four-link, and an independent suspension chassis. Add this new module to any one of these base configurations and you have an autonomous vehicle that is able to self-navigate and avoid obstacles.

Repto The Servo Robot

Repto the Servo Robot In the January/February 2009 issue of Robot there was an article by a man named I-Wei Huang, who had created small organic robots he dubbed Swashbots. I read the article and then later viewed Huang's YouTube videos, blog and website, www.crabfu.com. I found myself truly inspired. Here was someone with a similar skill set to my own and who had created simple and engaging robotic creatures. I could not wait to try and do the same.

Robot Remote Control Console

It is imperative that we incorporate a robust remote control capability into each of our robots or else, as history has shown, they will become our robotic overlords! If the engineers of Skynet, Colossus and HAL had considered remote control in their design these evil machines would never have been able to take over the local ship or the world. What a minute, those were just movies! (“Never mind…”) Actually, the reason I built the Robot Remote Control Console (RRCC) is far less dramatic and a great deal more practical than what you saw on the big screen.

Balloon Bot

As I have learned from my own projects, the major challenge in creating a successful robotic arm is the gripper. A robotic arm’s capability and usefulness is directly related to its ability to manipulate its environment. So when I read about a new gripper invented at Cornell University based on something as simple as a balloon filled with coffee grounds I was, to say the least, intrigued. After studying their novel design I was sure I could implement my own (cheaper) version and apply it to my next project.

Make Your Robot SEE

Not very long ago, any attempt at robot vision would have been an expensive and very technically challenging task. Digital cameras were once very expensive, the processing requirements would tax even the fastest CPUs, and you would most likely have to write your own imaging processing software from scratch. Today, you can purchase a decent USB webcam for less than $20, and even lowcost PCs and netbooks have significant processing power; and now, software is available that puts PhD-level image processing and robot control capability into the hands of novices.

Inexpensive, easy, pan-&-tilt mount – Make it from parts lying around your workshop

When I built my twin fuselage ParkZone Radian, I needed a small, light, inexpensive and universal pan-and-tilt mount. I could have used the pan-and-tilt part of the Range video Multiplex Easy Star mount, but that would have meant throwing away most of the mount. I could not find a commercially available unit to fit the bill, so I looked around my shop, my junk drawer and my scrap-wood pile and came up with my version.
