Lego WeDo Robotics, Week 1

Scjence Blog Steam Banner

This week was a busy one in the world of LEGO Robotics! On Thursday, we began a 3-week workshop using LEGO WeDo Robotics with second and third graders.


We began the day by discussion six types of simple machines. Then, after a brief introduction to how the LEGO software works, kids worked together to create and program robots with their LEGOs! They looked for simple machines within the designs of their robots, and they explored how to break instructions down for computer programming.

Check out some photos of the fun!

After discussing six types of simple machines and learning a little about the LEGO software, we began building robots!


These friends asked if they could work as a group of 3. Here they're starting to build an alligator robot.


This group's starting work on an airplane.


This group chose to work on a giant who gets pulled to a standing position with a crane mechanism.


Here we have legs that can be programmed to kick a soccer ball (or, in our case, a ball of aluminum foil).

We'll see you all next week as we continue building and programming!

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!

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!).

Mindstorms are Coming!

Scjence Blog Steam Banner

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.


First LEGO Workshops of 2017

We kicked off our 2017 LEGO science programming with a two-week LEGO WeDo Robotics workshop for kids in grades 2 & 3.


We briefly discussed simple machines and how they would be incorporated into the machines we’d be making. We also covered the basics of computer programming and how to use the LEGO software. Then, in pairs, kids chose which LEGO machines they wanted to build and program.


Since kids were able to choose their own projects, we got to see a much wider variety of creations! Here’s a collection of photos from both sessions!


The group gets started!


We're starting to get familiar with the LEGO software.


Building is underway!


This team chose to make the spinning top. During our second workshop, we watched a video about using this top in microgravity on the International Space Station!


This pair was also working on the spinning top!


This team made a pair of legs that kicked a "soccer ball" (made of aluminum foil).
