Mindstorms Home vs. Education Editions

There are 2 versions of the Lego Mindstorms EV3 kits and both of them, seemingly, offer pretty similar features. However, there are a number of key differences between these 2 kinds of sets that you may want to consider.

For one, the education models include the Robot Educator, GyroBoy, Robot Arm, Color Sorter, and Puppy. The Home edition features TRACK3R, EV3RSTORM, GRIPP3R, SPIK3R, and R3PTAR, as well as some other bonus ones.

The education models come with a rechargeable battery, whereas the home editions require you to purchase this separately. This set features a medium motor, 2 large motors,a programmable brick, sensors, 7 connector cables, and a charger.The home edition includes the same things, except it has 1 touch sensor instead of 2.

Initially, the differences between the two types of sets doesn’t seem like it would affect your child’s playing experience too much. However, the Education set has been specifically created to help your kids to learn more. While the home set also encourages kids to learn, the home version is focused on it more.

The programming app available with the education edition has more things for kids to do and learn about as well. As a result, this is the option that teaches or parents would want to use when trying to teach kids about programming and building.

Lego’s Mindstorms EV3 Home edition was made for individuals to use. The IR sensor available with this one is a little weaker compared to the education set and the precision of the ultrasonic sensors isn’t as great either.

However, kids can use the remote to be fully in control of their toy anyway, so these drawbacks may not end up being such a big deal.

The programming software is also pretty similar to the education version. One of the only big differences is that the education set features more programming blocks.

All in all, if you were looking for something that you could use to teach a class of kids about programming and building, the education set would be best. Having said that, you could still do a good job using the home version.

Final Thoughts on Popular Mindstorm Kits

So, that concludes our review on the various EV3 programming robot toys that are currently available. There are a number of sets available and it can quickly become confusing trying to distinguish the differences between them and which one you think your child would enjoy using the most.

Hopefully, we’ve provided you with all of the information you need to know to go ahead and make the best decision. The buying guide section includes some great information that clears up some of the confusion surrounding the different parts of the sets and the accessories that are available.

You can now feel confident about the set that you’re going to select and ensure that your kids have a blast while also learning about programming. These kits do a fantastic job of encouraging children to learn, while also having a lot of fun.
