Dancing Robots

In last week's Mindstorms workshop we put together robots and ran a simple demo computer program to get them to move. This week, we learned about creating our own computer programs and got to practice some ideas.


The LEGO Mindstorms software uses block programming techniques (similar to Scratch, if you’ve ever tried that out). Kids drag and drop various programming “blocks,” then adjust the settings of each block to direct their robots’ actions.


We began by learning about “Move Steering” blocks. These blocks allow you to control a robot’s motors to drive at various speeds and in different directions. At this step, the kids also learned how to download and run programs on their EV3 computer brick.


After kids were comfortable with getting their robots to move, we learned about sound blocks and display blocks. This allowed their robots to make a wide variety of sounds, from saying words to playing musical notes. They were also able to program their robots to display images on the screen. The most popular display option with this group were eyes.


Next week we’ll learn about using and programming sensors. Look out!

And now, some photos and an awesome video!

Full STEAM Ahead at Lincoln Elementary!


It was great to see so many familiar and new faces at Lincoln Elementary’s Full STEAM Ahead night earlier this month! The Winchester Public Library was one of over a dozen local STEAM-related organizations to host a table. About 300 people attended, and families had a chance to find out about all of the awesome science, technology, engineering, art, and math opportunities in the area.


At our table we had a demo of the LEGO WeDo robotics equipment that we do with kids in grades 2-5. We had information about all of the awesome STEAM-related programming and services we offer, including:

  • LEGO WeDo Robotics - Simple robotics and computer programming for grades 2-5, usually offered as a series of workshops
  • LEGO Mindstorms - More advanced robotics and computer programming for grades 4 & 5, usually offered as a series of workshops
  • STEAM Club - Various science-related activities for grades 2-5, usually offered as one-off single events
  • Legopalooza - Creative LEGO play for grades K-5
  • Preschool STEAM storytime - Storytime with hands-on STEAM activities for ages 3-6

Mindstorms' First Completed Robots

This week we really dove into using our LEGO Mindstorms equipment. The kids worked in two teams to create EXPLOR3R robots. The process of building these robots involved a lot of detailed exploration of building instructions, and they had to be very specific in where they placed their LEGO pieces.


After each team had completed building their robot, we used very basic programming elements that are already built into the EV3 brick, the small computer that controls the robot. The kids learned how to run a demo program to see an example for how the robot can move around a space.


Next week we will plug in our robots and begin computer programming. We will design a program to direct the robot to move in certain ways and, if we have time, we’ll learn how to write code that will utilize the robot’s computer screen and speakers.

Here are some pictures of our work, and videos of each of the robots running on the demo program!

One student brought one of his Mindstorms creations from home to show everybody. It was pretty awesome!

LEGO Mindstorms: Tons of Fun and Still Space!

Our first LEGO Mindstorms workshop began yesterday for kids in 4th and 5th grade!


This workshop will run for 6 weeks, going until Wednesday, April 5. We began with an Hour of Code, where we did some block programming to develop a Minecraft game. This gave the kids an opportunity to learn some basics about more advanced computer programming than we did in the LEGO WeDo workshops. Now we're prepared to tackle the computer programming for Mindstorms robots!


After we did a bunch of coding, we pulled out a Mindstorms kit and worked as a team to start putting together a simple machine. We will dive much more into this next week at our second session.


We had a great group, but there are still a few open spaces in this workshop. If your 4th or 5th grade child is interested, you can still register! Sessions run on Wednesday afternoons from 3:30-5:00pm, now through April 5. Register online here, or call or stop in to the library if you want more information.


Also, we only had time to do one Hour of Code computer programming activity. There are tons more that kids can do! Kids who participated yesterday may be interested in trying some more, or kids who are interested in signing up for the rest of the workshops can try what we did yesterday from home. Check it out at (psst: we did the Minecraft activity!).

You’ve all been waiting and asking, and we’re finally ready with a LEGO Mindstorms workshop!


Beginning on March 1, we will host a six-week LEGO Mindstorms workshop for kids in grades 4 and 5. It will run from 3:30-5:00pm and will go through Wednesday, April 5. Space will be limited, and registration is going on now!

We’ll be using LEGO Technic materials and a more complex computer programming language to create awesome machines. Take a look at some of the things we’ll be working on! And check out our calendar to register.


Chromebooks in the Children's Room

Did you know kids can now check out a Chromebook for in-library use? All they need is their library card!! Stop by the Children's Room for more information!
