This is really cool - can't remember if I have posted this info on RUS previously. Amazing stuff! Be sure to check out MoonMail - I would love to have something sent to the moon, especially something representing this blog. Love the video and the vision!

We have a bit of a Parallax Toddler revival going on at this thread over on the Parallax Forums. In thread, we began discussing bump sensors for the Toddler - that were nick-named "Twinkle Toes!" - Parallax Part #27312. As far as I know Carol Lynn Hazlett got the last set from Hobby Engineering. Above is a photo of the Blue Toddler. A pdf describing how they work is here (Chapter 8 from the Toddler Manual). See additional photos below including one to the the sensors, Gold Toddler, Toddler Control Board, and all the parts!
"I'm going to get them done with Solder Mask and Silkscreen so the would look finished. The difference was $3.00 per set with no mask or screen. I'm going with ExpressPCB right now. I will get 7 sets, (with one board left over). Looks like on set of Twinkle Toes boards, (right, left), will cost $11+ shipping. You will have to supply the two resistors. the Red/Green LED, and the headers. I'll send this order out Tuesday and get them back by Thursday. I'm taking two sets, erco gets one and Whit gets one. That leaves three. Should we make Ken buy a set? Also you will need 4-40 screws and nuts and the wire, available at most hardware stores and R/C outlets."Here is Publison's recreation of the PCB. So excited to be even a small part of reviving this bit of Parallax history!

Post Script - we also have a great conversation going with Harry Lewis at Blue Bell Design - see note in the Forum thread.

I removed the link to my robots and robotic's projects from the sidebar today (not a true 404 error, since I disabled the link). The information was really out of date - that is, it had not been updated in a very, very long time. A look through this archives show that I have many, many more robots and projects than are shown here.
The old info is here (April 24, 2007 post) and might be updated someday - it will take lots of work to get this in good shape!
Some great work going on here in Montana at X Team Robotics (X Team's blog is here). Photo above is with family friend Shannon Thomas (that is Shan on far right) at CR Anderson Middle School in Helena, Montana. X Team is a FIRST Tech Challenge Team and based out of Exploration Works! - a science and educational center in the city.
Looks like a really good group! I really need to get a club going here, especially now that I don't have a school team anymore!

|This is Zerak - Had it!|
|Zobor - I know I had this one too!|
|Zintar - Had them all - I guess!|
Per the post below, I was just reminded of Idea Toy Companies Zeroid Robots. I had these when I was little and had completely forgotten them! A quick Google search turned up the following. More as I find it. I would love to get some of these!
Here is what wikipedia says about Zeroids - https://en.wikipedia.org/wiki/Zeroids. Also found this vintage commercial on YouTube.
Another site here - http://www.zeroidz.com/Zeroids.html - and another really good one! - http://www.attackingmartian.com/zeroids_extra.html
And finally - These roboteers are building their own! http://danefield.com/alpha/forums/topic/15701-life-sized-zeroids-and-others/ Mercy!
|Love these old advertisements!|
We should start a online support group... What a fun couple of videos! The second one is my pal, Eric (aka erco)! He not only collects - he is an incredibly creative builder and shares all he knows by writing for Robot Magazine, Servo and widely on various robotics forums. I'm proud to count him as a friend!

This arrived today! The Parallax DHB-10 Dual H Bridge 10 Amp Motor Controller. Absolutely beautiful construction - very well designed and feature packed - just what I've all come to love about Parallax products - love getting a package with the Parallax packing tape!
It is a very compact design too. They are back in stock! Check it out here or just visit Parallax and look around. You will learn something - I promise!
|The new S3 has many new features and easy hack-ability!|
Just posted on the Parallax site - Parallax Insider News - Scribbler 3 Robot Update!
Here is the text...
Did you know that the origins of the Scribbler 3 (S3) robot started 15 years ago with the blue Scribbler and a BASIC Stamp 2? Since then, we’ve put over 20,000 of these robots into schools around the world. Many of the original robots are still in use too!
Educators are asking Parallax about the new S3 Robot. Many schools have been using the S2 for several years and are ready to order the new S3. Here’s a quick update for your planning.
- Availability: We have analyzed a dozen prototypes and approved the S3 for production earlier this week. We expect our first batch of production units to arrive at Parallax in August.
- Price: Final price has yet to be determined. We estimate that the S3 will be between $149 and $179. Volume discounts for class packs will be available.
- Stock Code: The Parallax stock code for the S3 is #28333.
- Placing Orders: We will enable pre-ordering for schools as soon as we have 100% confidence about the delivery date from our Rocklin, California warehouse.
- Features: Some of the S3’s new features include:
- USB-rechargeable lithium ion battery with up to eight hours of run time
- USB programmability
- XBee socket for future WiFi programming or robot-robot, robot-computer control
- Green color (original choice was yellow but this color caused too much internal infrared scattering)
The most important issue for Parallax and our customers is the programming software. The original Scribbler 2 (S2) Graphical User Interface (S2 GUI) runs only in Windows. Attempts to port it to Mac have now ended (it uses an obsolete code base in Perl). Upon release of the S3 we will have backward-compatible support with the S2 GUI so the robot can be programmed in the same tool.
Our official Scribbler 3 programming tool will become BlocklyProp. Parallax is openly developing the http://blockly.parallax.com interface around Google’s block programming language. We have customized this tool for the Propeller microcontroller which will enable students to have their first programming experience with a multicore processor. We plan on supporting the S3 in BlocklyProp with a series of blocks specific to the robot. A Chrome-compatible version is also in consideration for the 1-to-1 Chromebook schools.
To track our progress with BlocklyProp and the S3 robot please follow me on Twitter @ParallaxKen.
Follow Parallax's development of Blockly here too. Register and keep up for yourself!
You can see one of these at my house as soon as they are available! WOW - Can not wait!

|From the SeaDrone Facebook page.|
This is SeaDrone. More info is on the web at their site here. An article is also here on IEEE Spectrum about the idea's developement (Stanford brains again!).
The video above is very interesting. It really might be fun to develop an inexpensive hobby/educational bot (ala Phil Pilgrim's work on the Parallax Forums especially in this thread) - like the ELEV-8 for under water use.
This seems like it fits Parallax's mission. The SeaDrone above seems to have the "right stuff" for such an idea/concept - revised, of course, and made available in an ELEV-8 sort of package. It needs Parallax Control (brains) and the educational materials - but this could be really fun!
This really has me thinking about a new area of robotics that would be fun to explore - practical - and very interesting for students of all ages!

|The DHB-10 is a thing of beauty!|
Finally cracked under the great emotional strain of the new Arlo Complete Robot System release and ordered the DHB-10 Dual H-Bridge. It is back ordered right now - which should give me time to study the pdf product info...
My Arlo-like version is a bit Frankenstein-ish going back to the original 12 V Wheel and Motors, MadeUSA, Eddie, etc. - even have one HDPE platform and one plywood platform! ;-)
With the new DHB-10 - I should be able to play with new stuff up on Learn.parallax.com and use my Propeller Activity Board along with the new motor controller for some "up-to-date" fun without the nifty wooden box, of course, - maybe erco can send me some scrap plywood...

Louisiana Tech held its annual Robotics Competition (and demonstration) yesterday, May 6, 2016 in the "Tonk" or student center. The event was organized by Tech's Computer Science Department and sponsored by Pioneer Rx Pharmacy Software, and Praeses - two software development companies out of Shreveport. Both companies had representatives there.
The event was well attended and featured a maze competition, design competition (which was more like a demonstration of various design ideas - Social Media App Controlled Bot, Voice Controlled Bot, a Spiro-graphic Scribbler, Floor Sweeper, Card Dealing Bot, Nerf Gun - with targeting and tracking, Painting Bot, Package Sorting Bot, and several more!) followed by some further demos of hobby projects, and robotic toys and gizmos.
One of the graduating students had a Parallax ELEV-8, V3 - quad-copter - modified with obstacle avoiding sensors and successfully demonstrated his proof-of-concept.
The thing that impressed me most was the enthusiasm, and the diversity of the crowd in terms of age, gender, and ethnicity - it was a true cross section of the university and community at large. I would say over a dozen elementary aged children attended and were very excited and actively engaged. Students also clearly had non-technical friends attend the event to cheer them on!
There were many failures and partially completed projects - just shows that in robotics - real-life implementation is often a trial and error process of failure, revision and refinement. Roboticists are always - Back to the Drawing Board, Computer or Lab Workbench!
Special thanks to Ben Choi, Ph.D., Computer Science Department, for organizing this event and to !

According to Wikepedia, here:
R.U.R. is a 1920 science fiction play by the Czech writer Karel Čapek. R.U.R. stands for Rossumovi Univerzální Roboti (Rossum’s Universal Robots). However, the English phrase Rossum’s Universal Robots had been used as the subtitle in the Czech original. It premiered on 25 January 1921 and introduced the word "robot" to the English language and to science fiction as a whole.I've posted here many times about R.U.R. and it's influence on Robotics Under the Stole, especially the RUS favicon. Above are photos of the Cover and Title Page of R.U.R. and below is the RUS favicon.
