Jon,I saw this on the Freescale site while looking at some sensors for a project. I have their compass kit, and it is really nice. I expect that this will be just as good. Thanks for the informative description.
I had problems with the PC setup but they stemmed from PC memory chips that had gone bad. Set up on my Macintosh took a bit of time because I don't use the Mac for lab work and don't often use the command-line interface in the Mac's terminal window. The Mac required no additional USB drivers, but I did have to determine which USB device corresponded to the robot. From the terminal window I issues the command:
ls -l /dev/tty.usbmodem*
Which returned:
/dev/tty.usbmodem1d151
that identified the only USB "modem;" the robot. Then I could connect to the robot with this command:
screen /dev/tty.usbmodem1d151
The robot responded with:

Thanks very much Jon for featuring the Freescale FSLBOT in your column. I'm really looking forward to hearing about your experience with this kit. For anyone interested, there's more information on the product page www.freescale.com/mechbot . And of course, we'd love to introduce you to FSLBOT (or the team behind the bot) at the Freescale Technology Forum in San Antonio, June 18-24.
Jon, thanks for reporting this. This looks like yet another way to get more people involved in designing or programming robots and the technology used in them, along with the open-source projects I've reported on: http://www.designnews.com/author.asp?section_id=1392&doc_id=240629 http://www.designnews.com/document.asp?doc_id=239419
I agee Ann. With all of the embedded products currently available and new ones on the drawing board, a familiarity with programming is important for technology literacy in our society. A robot like this one is a good way to experiment and explore key technologies such as sensors and microcontrollers used in an abundant products like smart phones, dishwashers, washers and dryers, to name a few. The $199 price makes it a good buy to explore robotics and Mechatronics technologies as well!
Ann, one of the many challenges facing engineers is staying current with new and emerging technologies. The Freescale TWR Robotics development platform is a cost effective training tool for learning evolving technologies.
You're right mrdon. This would be especially useful if you could swap out the parts as they become obsolete or to learn different current technologies.
Hi, Jack. You probably want to keep the TWR-MECH board for all experiments because it provides eight servo outputs and can accept two add-on sensor boards. I have the LFDA7455 3-axis accelerometer board and the LFDA3110 magnetometer board inserter on my robot, so it can provide accurate magnetic headings. The TWR-MECH board has an edge connector that ensures compatibility with other Freescale Tower boards, so you can "stack" on other boards you want to experiment with or test. The TWR-MECH board has touch-sensor inputs and plenty of digital I/O pins, too. I'll have more to report later this week.
Jack, that's a really interesting concept--parts specified and installed so they can be swapped out to update the robot or try out different technologies. Jon, was there any hint of this possibility from Freescale?
Jon, this looks way cool! With all of the discussion on STEM this looks like it would be a great addition to any school program. I used to teach a robotics club at my son's middle school - this guy would have been perfect and the price is right! I'll be very interested in learning about your experiences with it. I am of the same BASIC era with the TI99/4A - Any programming language is worthwhile in teaching students what programming is about and this should be a great starting point to get folks excited about robotics, sensors and programming in general! Thanks for sharing!
Thanks for the new references, Ann. Good sites. A friend had surgery with a da Vinci robot and said it was an interesting experience to have a machine working inside him. Of course he was anethesized!
I'm sure Freescale will have the robots at the Technology Forum. They might even have some robots available so people can try simple programs and learn more about how the Tower Mechatronics board works. I did see many Tower-related hands-on sessions on the Freescale Techonolgy Forum Web site: http://www.freescale.com/webapp/sps/site/overview.jsp?code=FTF_2012_AMERICA_TECH_SES_OV.
Because the robot uses BASIC, I agree with Nancy that it would offer a good way to introduce kids to STEM topics and have them do things with a real-world device that includes motor controls and sensors. It wouldn't take much to increase the size of the metal mounting plate so people could add an ultrasonic distance sensor, limit switches, IR detector, and so on. I'll also add a pitch for Parallax, a company that sells many robot kits and plenty of add-ons. The company also has many good reference books and manuals with experiments. Look at the BoeBot, for example. www.parallax.com.
My wife had daVinci robotic surgery this past January and was walking about within a day. Using teleoperating machine control techniques and haptics, doctors are able to perform surgeries that are less invasive because of these highly accurate robotic machines. In addition to Parallax offering BoeBot kits that are great for STEM projects, they also provide a BoeBot shield that can be attached to an Arduino as well.
Good comment about the Parallax BoeBot. I just saw the new board for Arduino shields. That gives students and teachers much flexibility in what and how they teach.
With LEDs dropping in price virtually every year, automakers have begun employing them, not only on luxury vehicles, but on entry-level models, as well.
The 3D printing revolution seems to have a knack for quickly moving technology ahead by way of collaborative effort and even a little friendly competition -- all of course in the name of scientific advancement.
Advantech has launched a new series of motion-control I/O modules to meet the increased demands that come with more distributed industrial systems that require control of a growing number of axes and devices.
Using almost 200 light-emitting diodes in the front and back of the new 2014 CTS, Cadillac designers are showing how LEDs can change the character of a vehicle.
