This is the initial construction of a catapult. The base on which we will place the rest of the robot. The goal of this construction is to give the catapult the ability to rotate.

This attachment was intended for and tested on the Gazon, LEGO Education SPIKE Prime competition robot. It is meant to help the robot complete the 9th mission of the FLL Cargo Connect competition.

These are 3D building instructions for an active pinless attachment from LEGO Education SPIKE Prime set. The attachment is used along with the Gazon robot to push mission models.

First version of a reusable gear attachment. By following the same principle for assembling the attachments you can change the direction of the gear wheels and build powerful attachments that could accomplish missions in any direction.

Forth version of a reusable gear attachment. Again, it powers two axles and this time there is a lever connected to one of the axles.

The rotation frame requiers an NXT large double gear wheel that is not available at the EV3 set. You can use the instructions below to construct a similar mechanism from Mindstorms EV3 set

Second version of a reusable gear attachment. This time the black gear wheel is at the top. It is useful when you are constrained by space.

Building instructions for this part of the BigDaddy competition robot

You can position the motors on the construction in a number of different ways. We are exploring the advantages and disadvantages of each of them. These are building instructions for the first way to position the LEGO Mindstorms EV3 motors.

Third version of a reusable gear attachment. In this scenario a single motor could power two different axles in two different directions. If you use it to accomplish a mission do not forget to send us a video. We would love to see it.

With this LEGO robot attachment from LEGO Mindstorms Robot Inventor we accomplish the Rowing Machine from FIRST LEGO League 2020. The attachment works like a hook that catches the wheel of the Rowing Machine mission model and pulls on it. There are gear wheels that transfer the power from the robot motors to the hook at the end. This attachment shows the principle of catching things

This was an idea. You would we demonstration a multi-axle power and rotation transmitting box. Well, here it is. Build it. Start it. And see how the power from the motor is transmitted through different axles. The lever will demonstrate it.

This is a robot attachment built only with parts from LEGO Mindstorms Robot Inventor Set. The goal of the attachment is to accomplish the FIRST LEGO League 2020 RePlay mission call Treadmill. The attachment has two gear wheels that could transfer the power from the motors to the wheel. The wheel is the one that is accomplishing the mission as it rotates and rotates. The attachment is pinless.
