Bot State of the Art

Sunday, August 30th, 2009

Around oomlout HQ we have many loves, and its safe to say that both “fun” and “robots” count among these. So when Make magazine asked for our thoughts on where the future of robots was headed we were only too happy to toss our two cents into the ring.

Our thoughts on the future of robotics…

The Oomlout Team (makers of open source robot and microcontroller kits)

The coolest thing in robotics right now is fun!. It sounds hokey, but for the first time, the mechanics, electronics, and programming tools required to make really amazing robots are available to just about anyone. No longer are robots forced to live out their days mindlessly assembling cars on factory floors or sliavishly performing demos in university labs. Robots are moving onto our walls, our floors and countertops, and our balconies. They’re making pretty pictures, entertaining us at parties, even twittering the “mood” of the tomato plant on our porch.

Are they doing these things because they are necessary? No. they’re being put to these ends mainly in the interest of fun and exploration. We believe that from this atmosphere of frivolity, the serious robotic future we’ve long been promised will finally take shape.

We were a bit awed by the robotic elite we were featured beside, from our favourite, the creator of some of the funnest and most emotionally evocative robots we’ve ever seen (I-Wei Huang of Crabfu Steamworks). To the big players in the industry (Mark Tilden of WowWee, Matt Trossen of Trossen Robotics, Ken Gracey of Parallax, and Dave Hrynkiw of Solarbotics). Admitedly robot development around oomlout has slowed of late, but we have several projects in development which we think will show that our place within this crowd is warranted (and show that fun and robotics go hand in hand).

Our Wingshields Have Landed

Friday, August 21st, 2009

The hard working folks over at Wingshield Industries have kindly bundled up a few of their latest kit and sent them our way.

The Screw Shield is perhaps the most useful shield we’ve seen to date. It breaks out every digital and analog pin on an Arduino Duemilanove to sturdy screw terminals. Allowing for the use of many more wire sizes, and eliminating the headaches caused when a wire, unnoticed, slips out of place. (available in the oomlout web shop for £8.00)


A Few Chips For Your Next Project

Tuesday, August 18th, 2009

One thing we really love doing around .:oomlout:. HQ is taking things apart. Be it an ‘antique’ printer or cute fuzzy toy nothing is safe. However this habit leaves us with box upon box of great components begging to be used.

With many of the funner pieces (motors, solenoids, little light bulbs) the current they require is much higher than a single Arduino pin can provide. To get past this we found ourselves using chips (integrated circuits), and a pair of chips kept finding their way into our projects. Given our quest to fill every electronics parts bin with the funnest and most useful parts we thought it appropriate to start selling them through the store. Thus we’re happy to announce two fun products now available

Dual H-Bridge Driver Chip – L293D

This is a great chip which once wired up can control the direction of two DC motors or one bi-polar (4 wire) stepper motor. We have an in depth tutorial in the works, but for the moment have thrown together a one page quick start guide (available here with a copy shipped with each order) (available at the oomlout web shop for £2.50 )

Octal High Current Transistor Array – ULN2803A


Another great chip, when driving high current loads a transistor is often required. This chip houses 8 high current transistors, with current limiting resistor and flyback diodes attached internally to make for very clean wiring. Simply drop it in and start driving solenoids, high current LEDs or motors in one direction. (each pair ships with a printed quick start guide available here ) (available at the oomlout web shop for £2.98 a pair)
