Product Description
The EV3 Brain (or Brick) is a great design, but if you have to swap out the battery between competition rounds, or share resources between classes, it can be a pain to get everything connected back up in the right place.

How, exactly, was this thing attached? Why are all my right turns now left turns? The manipulator is supposed to be going UP, not DOWN!! What port did I use for the gyro?


My students were getting quite frustrated, and I decided there had to be an solution.

My approach was to design a cradle that holds the brick (brain), yet allows the students to quickly and easily swap out the rechargeable battery, or even the entire brick. I really like the way it turned out.

Since we share bricks between classes this cradle has been a lifesaver. One group doesn't have to take apart their robot in order to share the brick with a group in the other class.

Did a student forget to put the brick on the charger? With this cradle, battery swap-out takes less than a minute. Just think if your team is between rounds at State and realizes the battery is almost dead! Quickly and easily swap in a fresh battery without worrying about getting all those cables plugged back into the right ports.

I allowed my students plenty of flexibility in design. I just required that they start with this simple cradle.

I hope you find this as helpful as I do. Please let me know!
