EV3 Programming: Motor Blocks

Screen Shot 2018-10-09 at 3.35.18 PM

We have had a lot of fun using our EV3 bricks for a lot of things, such as programming them to play our favorite songs and accomplishing fun tasks we make on our own, but by far the most fun part of EV3 comes when you add motors into the mix! Motors allow you to build a robot that can drive around or build a machine with moving arms or rotating turn tables. Motors are obviously especially important in EV3 for competing in FIRST LEGO League (FLL). How else can you move around the field and accomplish all those cool missions?

In this article, we will teach you about the parameters on a motor block, different types of motor blocks, and the basic types of turns.

Remember to Have Fun with Your EV3!

One of the FLL core values is about having fun and enjoying what we do. Sometimes it is easy to get caught up in using LEGO EV3 for FIRST LEGO League, to learn about simple and complex machines, or for other schoolwork. FIRST encourages us to have fun while we do our work. But, it is good to remember to make sure you take some time to have a break and to just have fun, too! When you have time, you should make up your own missions and challenges! By making your own challenges you can learn, have fun, and take a break from all the stressing work of robotics.

Crabs, Couches, and Armchairs: Building Pieces for Extra Support

crab intro

When you are building with LEGO Technic, sometimes you need extra supporting pieces on beams to keep your model from falling apart when you handle it. This is especially important for LEGO robots used for competition. We thought up some ways over the past three years to help with this problem. We will share some of those in this blog post.

The Extra Beam!

LEGO is pretty generous. In all of their sets, they have some extra pieces that are left over after following building instructions, but LEGO only gives you very small extra pieces, like studs, connectors, half bushes, etc. LEGO almost never gives you large extra pieces. If you have a large piece left over after building a set, check through the instructions again to see if you missed putting that piece in the model as part of the steps. In recent LEGO sets, each step has an inventory listed for the step. To avoid leaving pieces out while we build, we like to find the pieces for each step and make sure we use them all before moving on. When we have a large piece like a full brick or beam left over, we scan the inventory listed for each step to look for the type/color of piece we have left over. Usually, we find the step we overlooked that piece. It has happened to us many times in different LEGO sets we build.
