DARPA Robotics Challenge (DRC) Begins

The DARPA robotics challenge aims to jump start the development of humanoid robots that can do dangerous tasks that right now can only be performed by a human. DRC will provide funding for the participating teams and an expected $2 million prize to the winning team.

The Defense Advanced Research Projects Agency (DARPA) is part of the United States Department of Defense and is charged with promoting development of new technology that can aid the military.

The DARPA Grand Challenge of 2004, 2005, and 2007 offered $1 million and $2 million prizes for cars that could drive themselves and led to the development of the Google Self Driving car.

Adding a Relay to Your Micro-Controller Project

Micro-Controllers are amazing devices, with built in memory,  a cpu, and input and output ports, they’re are like a complete compter system on a single chip. The digital output ports can directly control small current devices such as LED’s that require 5 volts or so and only a few tens of mili-watts. But what if you want to use a micro-controller to control a device with larger current requirements, for instance a 100 watt light bulb or a fan. One of my favorite ways to accomplish that is to use a relay. A relay is like an electronically contolled switch. Relays come in many different configurations, but today I will be discussing the new 10 Amp Relay Board available at Roslyn Robot Company. This inexpensive board can be controlled by any 5 volts micro-controller, or even by a small switch with a 5 volt power source, and can control devices with power requirement of up to 10 amps, and 250 volts. It features a built in switching transistor to reduce the current required from the micro-controller to a very low value.

This relay board has two screw down connectors. One for the micro-controller side, and one for the device you want to control. On the device side the terminals are labeled NC, COM. and NO. They stand for Normally Closed, Common, and Normally Open respectively, making this a Single Pole Double Throw switch.


The video below does a great job of explaining the different type of swithces.

Send in Pointman before People

You’re a police officer responding to a burglar alarm call. You arrive at the scene at 2 am, alone. It’s a pharmacy in a desolated area. The door has been kicked in. Now what?  Do you draw you gun and go inside? Is there someone waiting for you in there?

Sounds like a job for Pointman, watch the video

History of an iPhone App

Roslyn Robot Company released the Weej App to the Apple App store in June of 2010. The Weej app is a game, its sort of a cross between a Ouija Board and a Magic 8 Ball game. To play, you touch and hold the screen and ask your question out loud. Then release the screen and wait for the Spirits to respond. After a few seconds the planchette or shuttle will begin to move rapidly and spell out an answer to your question one letter at a time.

Since this was our first offering in the app store we had no idea what to expect.

We were off to a great start, with 24 sales the first full day. We were excited and wondered how many we would sell on day 2.

Yikes, only 5 sales on day 2.

Gradually sales settled down to average about one sale a day. We did no advertising and no updated versions, and sales remained steady at this rate for about two years.

Only in the last few months for whatever reason, did sales start to pick up. I think now we are averaging about 2 a day.

Every once in a while you get a surprise like “Wow, we sold 5 copies in Belgium yesterday, wonder what’s up with that?”

We sell Weej for $0.99 on normal days. We make Weej free whenever there is a Friday the 13th and on Halloween.

In the chart below you can see that the first time we did this there were 500 downloads. The second time 350 downloads. After that it fell to about 100 each time we offered it for free.

We are about to start a social media campaign and we will see how that affects sales.

Robotic Fish

New from Osaka City University, a robotic fish that propels itself using magnets instead of motors which results in huge energy savings. It has the ability to propel itself forward as well dive or surface, and it movements are very lifelike and do not resemble what we tend to think of as robotic.

Looks tasty too!

MIT’s “Hugable” Robot



At first glance “Hugable” may look like a toy, but is actually a very sophisticated machine.

The Huggable™ is a sophisticated robot featuring a full body sensitive skin with over 1500 sensors, quiet back-drivable actuators, video cameras in the eyes, microphones in the ears, an inertial measurement unit, a speaker, and an embedded PC with 802.11g wireless networking. An important design goal of the Huggable™ is to make the technology invisible to the user. You should not think of the Huggable™ as a robot but rather as a richly interactive teddy bear. The actuators are designed to be silent and back drivable so as the Huggable™ moves, you do not hear or feel gears. The movements, gestures and expressions of the bear convey a personality-rich character, not a robotic artifact. A soft silicone-based skin covers the entire bear to give it a more lifelike feel and heft, so you do not feel the technology underneath. Holding the Huggable™ feels more like holding a puppy, rather than a pillow-like plush doll

Living with Robots

Yesterday at the Sundance Film Festival Honda debuted”Living with Robots” a short documentary and the sixth installment in its series “Dream the Impossible”.

This film talks about how far Honda has come with its humanoid robot ASIMO (Advanced Step in Innovative Mobility) in the past twenty years

When the ASIMO program started, creating a biped walking robot seemed an impossible task. Today ASIMO walks well, although it will certainly improve as time goes on.

Honda’s focus has now shifted toward the Artificial Intellegence aspect and is working hard on making ASIMO smarter.

Watch the film here.
