Earlier this month we arranged for a Subaru Indiana Automotive (SIA) plant group tour in Lafayette, Indiana. The 2.3 million sq. ft. plant was officially opened in 1989, but has undergone some remarkable expansion the last few years to a facility that has now almost doubled in size. Cars were coming off the production line every 63 seconds when we visited; it will be under a minute by November.
We had 29 people sign up for the tour, which takes you through the stamping, robotic welding, paint, inspection, and assembly areas. Most of the tour is in the overhead catwalks, which offers a great view weaving between the 16+ miles of overhead conveyors hauling parts and vehicles. You get a chance to see body parts made from giant rolls of steel, a symphony of over 800 robots welding and assembling car frames and components, and then it all coming together into a finished product that’s driven off the assembly line. With over 4 million square feet of building space, we hardly saw it all but it still left both young and old amazed at how this small city of over 5000 workers creates soon to be 390,000 drivable vehicles a year!
Thanks to SIA for allowing us to book the group & giving us the great tour. Everyone that could make it loved it and we seem to have enough interest to do other group tours in the future.
Another good regional resource for kids STEM activities is Wonderlab in Bloomington, Indiana. Besides being a fun place to visit, they also offer summer day camps for kids through 6th grade (and mentoring opportunities for those older) that can range from crazy contraptions and electronics/engineering to TV technology. They also have occasional special events, often on weekends or during school breaks, that anyone can sign up for.
Bloominglabs, the community makerspace in Bloomington, put on a 3 hour Brainbot building workshop over spring break at Wonderlab for kids and adults. Since we had some experience teaching kids to solder, ended up helping with the workshop and now helping to improve the workshop instructions. Bloominglabs also helps the Monroe County Library with speakers for the summer Make It Digital series, put on Makevention every year, and have an open shop night every Wednesday evening for those interested in making.
As we work towards creating a Putnam County makerspace, the robot building workshop is a good example of what Castlemakers will offer. Of course a makerspace is much more than just classes. But the goal is sharing/helping people to learn skills with arduinos/microcontrollers, mechanical devices, 3D printers, and more. And with the right physical location that may include welding, woodworking, jewelry making… all things that makerspaces in other cities offer.
If you haven’t heard of Theo Jansen’s Strandbeests, and even if you have, the Chicago Cultural Center has a fabulous exhibit for anyone interested in mechanical creatures. You get to see what an eccentric artist can do when combining engineering and art. Jansen’s wind powered beach creatures have evolved over the last 25 years, getting more sophisticated by storing wind energy, sensing when walking into the water, and even self-correcting to prevent them getting stuck. Some even anchor themselves if they detect a storm, all without any electronics just plastic pipe, cloth, and recycled bottles.
Check the schedule if you go, you can watch a 42’ long Animaris Suspendisse walk or they might actually let you move an Animaris Ordis by yourself! The exhibit also included the evolution of the creatures and a small case of what other inspired people in the making community have done with his designs. Hamster powered Strandbeest anyone? How about 3D printed Strandbeests? The Segway like device inspired by a Strandbeest was pretty impressive too! Anyone interested in building a Strandbeest here?
The Chicago Cultural Center is a beautiful building itself and just across the street from Millennium Park – you can see Cloud Gate from many of the windows on the east side of the building. Make sure you check out the other exhibits in the building and look at the incredible dome on the 2nd floor of the Center.
I’ll cover the workshops on making your own greeting card using a electronic (vinyl) cutter and making a custom acrylic keychain with laser cutter in a future post…
In today’s meeting we looked at ozobots & dug out the cubelets to try and get the Bluetooth control working. Technical difficulties prevented the cubelets from working with the remote control app. But the ozobots were a bigger hit anyway with both the kids and adults there.
Ozobots are tiny dome like robots that have optical sensors that are used to follow lines. These lines can also program the little guys, through shapes and colors. Using a marker they will follow the line you draw but by using different color patterns they will change speed, change direction, pause, stop and even count.
It was amazing to sit back and watch the kid’s creativity. After a brief introduction to the ozobot, the kids discovered much more on their own. Following mazes and lines drawn on paper, along with guessing which branch the ozobot would take dominated the afternoon.
The kids decided to “test the robot’s artificial intelligence” by creating questions that the robot could ‘answer’ by choosing the right path. The maze they created started with simple questions like 4 divided by 4, then progressed into more difficult questions like which country created french fries. There were plenty of death traps and black holes along the path for the ozobot if a wrong decision was made. They decided to conduct tests for both ozobots , you can watch one trial in this video. Of course the robot didn’t really evaluate the questions, just took a random path, but they still had fun.
The ozobot color changing capability was a huge hit (different colored lines cause the bot’s LED to match the line color). They are somewhat sensitive to line width, but it’s not a huge factor. The large dry erase board attempt didn’t work well, the bot would eventually scrape off some of the marker then stop. Ozogroove, the dancing app, was pretty useless on a Nexus 7 – don’t bother to install it on that tablet at least.
We’re going to have to experiment some more with hand drawing the ozocodes, the programming language for the robot. It seemed to be inconsistent, sometimes working and sometimes not, even for the same color coded lines. Printed ones worked great. There’s also a coding language, ozoblocky, but that will be a future meeting.
Our Brushbot build this last Sunday turned out well. This is a popular kids project, to the point now where you can even buy kits to make them. We did it the old fashioned way with a toothbrush, pager motor, battery and double-sided tape. Thanks to Dollar Tree and a bulk order of motors from China, they cost less than $1/piece and many of the kids made them with their own toothbrush!
If you’re like many parents looking for summer opportunities for your kids, this coming Saturday February 21rst, the 26th Annual Summer Camp Fair will be going on from 11-3 in Indianapolis at the Fashion Mall. I try to keep the events page updated with other regional STEM opportunities, if you hear of something you feel others would be interested in let me know.
Also a few of the adults have started building a Robobrrd, a felt-covered interactive robotic bird made of popsicle sticks that uses an arduino micro-controller. At this point it’s still for adults (or older kids) as we figure out how it could best be made by the larger group. Feel free to join us, you’ll be helping other kids down the road. We’re meeting on Tuesday nights at 7 pm, 605 Crown Street at least through March. Again you can always check the events page.
This Sunday we’ll be making Brushbots using a toothbrush, vibrating pager motors, and a battery. We’ll have a small racetrack to test them, so be thinking about how they can be modified to be more stable along with what kind of bristles would work best and how to steer them.
A very short video of the prototype in action you can view here.
Anyone is welcome to join us, we’ll be meeting at 605 Crown Street at 2 pm on Sunday February 15th.
At our first meeting of 2015, the kids brought in things they got or made over the holidays. There was a pretty wide range – from Ryan’s “Cool Circuits” and Boyd’s Tinker Crate (creative building/experimental kit in-a-box that comes monthly) to an owl pellet (no, Eli didn’t ‘make’ that!). Very encouraging seeing all of the other STEM related things they brought and all seemed to have a great time showing them off and trying them out.
We talked about some upcoming projects: Brushbot parts are on the way, watched part of a short demo reel on Robobrrd, and discussed a couple of different paper air rocket launcher options we could build. Based on the votes we’ll try to do both of the latter two, but both are still early in the planning stages.
We’re going to prototype the Robobrrd first, it looks like fun project that could involve both young and older kids. It’s a robotic bird made out of popsicle/craft sticks, felt, glue, servos, and controlled by an Arduino controller – there’s lots of options and a good open-source community behind it. Several adults (and a DePauw student that’s volunteered) will be building the prototype on Tuesday evenings. Let Chris know if you’d like to participate or help.
We also briefly discussed the catapult build and developing a more regular schedule given the problems last month of finding a regular time. For now we’re going to meet on Sunday afternoons at 2 pm, working on a project every 2 weeks and a more general meeting once a month. Our next meeting will be February 8th and will be either the Brushbot build or work on the big trebuchet. After the meeting most of us walked down to the Brickmania Lego event at City Hall.
Kicking off our Make it on Mondays series we have arranged for a brief overview of 4 common robotics groups; VEX, Lego, FIRST, & SeaPerch, including what some of the local Putnam County programs are doing.
Area 30, Putnam County 4-H, and the DePauw Robotics Club will be there talking about what they’re doing with Robotics, along with some information about other regional competitions. If you’ve heard about VEX kits or Lego Mindstorms in Putnam County; or maybe just heard/wondered what is FIRST Robotics or SeaPerch from friends in other parts of Indiana, we’ll try to have some more information for you at this event.
This will be an open question/sharing session at the end, so if you have information you’d like to share about other Putnam county robotics groups please let us know or simply show up and share it with everyone! We’ll be meeting in the Community Room at Area 30 next Monday November 3rd at 7pm where you can see one of the robots that have competed at regional events.
Bloominglabs, a makerspace in Bloomington Indiana, has their Makevention this coming Saturday, August 30th, from 10 am to 4 pm. It’s at the Bloomington, Indiana convention center and you can read more about the event here: http://makevention.org/
Last year they had FIRST & the FIRST Lego League robotics equipment there, it looks like the local high school team at least has a booth this year. Should be a good opportunity to see some interesting maker projects and if you’re interested in robotics get a feel for what’s involved in fielding a FIRST robotics team.
I’m working on Making speaker series this fall to start in October in Putnam County. The first topic will be on the different robotics team competitions – including have our local VEX robotics team speak about what they’re doing.
There’s also an upcoming Robotics Encounter down in Scottsburg Indiana for kids in grades 3-12 on September 27th. It’s sponsored by the local 4H/ Purdue Extension office down there, but out-of-towners are encouraged for the 10 am to 3 pm workshop. You can read more about it in the flyer or call the Floyd County Extension office at 812.948.5470.
Don’t forget that this Saturday, April 5th, from 10am to 1 pm in the Community Room there will be a robotics competition exhibition at the Area 30 Career Center in Greencastle. A flyer for the event describes a little more on it and the public is welcome!
Club Cyberia, a Makerspace in Indianapolis, is having an open project day this Saturday from 1-6 pm. I’m heading over to visit & to learn more about how their model works – update later!
