The course uses Lego Mindstorms NXT robots and a curriculum based on one developed by Carnegie Mellon University.

<br />
Of interest to Lego Roboticists everywhere is the announcement of the Mindstorms EV3 set.<br />
This is Lego's latest and greatest, and it has some neat things to offer.<br />
<br />
1. The "Brick" has been redesigned, and now works with Linux, IOS, and Android operating systems.<br />
2. There are 4 motors and 4 sensors. One sensor is an Infrared sensor.<br />
3. There's a new graphic tool for guiding assembly.<br />
<br />
It will be available mid-year, and the list price is $350, plus $100 for software.<br />
<br />
Here's the article from IEEE Spectrum:<br />

I, of course, said yes. It turns out that the arm was surplus equipment from a lab at St. Mary's University here in San Antonio, and Djaffer had rescued it from the trash heap.<br />
<br />
The robot came without much identification (no manufacturer's plate, no owner's manual). However, the motors have nameplates and their manufacturer is still in business, so I should be able to get what I need from the Internet. This robot has 6 motors and a nice gripper. Each motor has a position encoder and gearbox, and there is a limit switch for each degree of freedom. Motors are 12 volts. Power and signals are carried by 26 gauge wires to a 50-pin D connector.<br />
<br />
I have not applied power to any part of the arm, because there's still information I need.<br />
<br />
For size reference, here's a photo of my grandson Christopher interacting with the robot.<br />

The kids (about 40 of them) were polite and attentive, and they asked very good questions during and after my presentation. I showed them the "Rat Brain" video, the "Robot Actress" video, and the "Kitchen Robot" video. After the club meeting was over, I gave Ms Hernandez a copy of my presentation and all the videos.<br />
<br />
I'm looking forward to talking again to this fine group of future robotics engineers.<br />

I gave a slide presentation, then showed some interesting video clips. The kids were very attentive and polite, and asked very good questions. I think that they will be well prepared to design the next generation of space robots. <br />

Thanks to Mrs. Jenness Davidson for inviting me, and to the principal and other faculty for making everything go smoothly.<br />

Today we had the last class meeting for the 2011 edition of RoboticsForGrandparents. There was no programming to be done, but I did give the class a challenge - to build the "five minute bot" from nxtprograms.com. They did fine, except that I left out two pieces from the parts kit. One student was able to invent a way around that problem, so we had a bot that would run around on the table. An added bonus was a visit from Mike Henry, a FIRST Senior Mentor who likes to talk up youth robotics. He identified and compared several robotics programs available in the San Antonio area, and showed us some of his robots.tpobrienjrhttp://www.blogger.com/profile/14372961857979761915noreply@blogger.com0tag:blogger.com,1999:blog-4620877214687748874.post-12659141675018029872011-09-21T10:20:00.004-05:002011-09-21T10:20:57.195-05:00Interest in "Robots I Have Known"It appears that the word is getting around about my presentation "Space Robots I Have Known".

All seven students showed up, and I think they had a good time playing with the robots. Everybody got the bot going and made it beep and talk, which is a great start. I think they're already having as much fun as the 5th graders!<br />
<br />
One thing that's a problem is the lighting in the room. When we switch from looking at the projection screen to looking at laptops it is a problem for some. I'm going to close the blinds next time. I sure wish the Mindstorms brick had louder audio. Maybe I will do something about that.<br />
<br />
Next week we'll try to get the bot to move and turn.tpobrienjrhttp://www.blogger.com/profile/14372961857979761915noreply@blogger.com0tag:blogger.com,1999:blog-4620877214687748874.post-33903461599687722192011-09-06T14:26:00.000-05:002011-09-06T14:26:13.080-05:00Dextre robot works aboard Space StationThis article,<br />

<br />
tells about some recent activity with Dextre, the special purpose end-effector that's now in use on the Space Station. When I first heard about it in 1977, it was thought to be something more complex than just a gripper, but this is *amazing*! It can ride around on the tram while the Canadarm2 does other things, and it has small tools that it can use to fix things. It is also capable of teleoperation from Mission Control! The only limitation I see is that only one of Dextre's arms can be moved at a time, with the other locked in place. That's a minor limitation in my opinion. Good work, ROBO team!<br />

Fortunately, I was able to find a laptop on Craigslist that will fit the bill. It's a bit newer, and has a freshly installed Windows XP as well as USB ports and wireless capability.

<br />
This is a six-week class, meeting once per week.<br />
<br />
The first class meeting will be at 9:30 AM on Monday, September 12th. It will last 1 hour and 15 minutes.<br />
<br />
Class dates for your calendar:<br />
<br />
September 12, 19, 26<br />
October 3, 10, 17<br />
<br />
Due to the limited amount of lab equipment available, enrollment is strictly limited to 8 students.<br />
<br />
Students should have a basic familiarity with the running of applications under Windows, but do not need any knowledge of programming, engineering, or robotics.<br />

Most of the class sessions will include a few minutes of lecture followed by hands-on lab.tpobrienjrhttp://www.blogger.com/profile/14372961857979761915noreply@blogger.com0tag:blogger.com,1999:blog-4620877214687748874.post-42041216611316048422011-04-19T13:03:00.000-05:002011-04-19T13:03:19.780-05:00Encino Park Robotics ClubLast Friday, April 15th, I visited the Robotics Club at Encino Park Elementary School and gave a slide presentation "Space Robots I Have Known". At the beginning of the presentation, I passed around a couple of space program artifacts from my bookshelf: a wooden mockup of a spacecraft "black box", made of white pine, and a pushbutton "ENTER" switch from the Shuttle Orbiter's Cockpit Avionics Upgrade program, which was cancelled.<br />
<br />
The presentation took about 40 minutes, and was followed by viewing of some live-action and animated videos showing the space robots in action.<br />
<br />
The club members, all 5th graders, had many interesting questions about what those robots could do.tpobrienjrhttp://www.blogger.com/profile/14372961857979761915noreply@blogger.com0tag:blogger.com,1999:blog-4620877214687748874.post-67454928033753941092011-04-19T12:55:00.002-05:002011-04-19T12:55:35.786-05:00JPL Mars Rover "Curiosity" article and great animationThis article from IEEE Spectrum Robotics newsletter shows the complete landing and deployment sequence of this new robotic rover. <br />

I have found a good starter robot design that may just do the trick. I'll be using the SPOT design from James Floyd Kelly's excellent book, "Lego Mindstorms NXT-G Programming Guide". The students (each team) will get a bag of parts and a photocopy of the build instructions for SPOT. I have found that having the parts pre-picked saves a lot of time.<br />
<br />
On the right you see a picture of SPOT from the book. Between now and next September I will tinker with SPOT and see how he fits in with my class lab exercises.tpobrienjrhttp://www.blogger.com/profile/14372961857979761915noreply@blogger.com0
