Probably the simples trick for pinless attachments that we've found. It is a construction build in just three steps. Simple as that. But it has a lot of potential to teach you how to use pinless attachments. Pinless attachments are very useful during FIRST LEGO League and World Robot Olympiad competitions.
Building instructions for the Pinless Rubber Band Attachment:
Building instructions for the Rubber Band Attachment
These are building instructions for one of the greatest LEGO Mindstorms attachments that we've built. Super simple and easy to follow and at the end, you have an attachment with a rubber band that controls a lever and that could lift objects from the field. It could lift them up. Also because it is with a rubber band you don't need a motor and you could use the motor for other attachments.
- note that I have added two angled beams and an axle to illustrate how you could use the slide as an active attachmen;
- note that you could attach it to the brick both sides, depending on which technique you would like to test. Use the video as a reference.
- you should attach it to the motor, depending on the orientation of the motor.
This LEGO attachment connects a LEGO Mindstorms EV3 Motor with a LEGO Technic Linear Actuator. The connection is through a couple of gears which makes the whole instructions quite interesting and useful as an example.
The attachment was used during FIRST LEGO League 2014 Robotics competition.

Another example for a quick pinless attachment build with LEGO Mindstorms EV3 robots.
The attachment shows how to do build a pinless robot attachment with LEGO EV3 Mindstorms.
Instructions for building the quick attachments for this LEGO robot
This LEGO Mindstorms Attachment has three gears, one frame and two axles. The goal of the attachment is to use the gears to change the direction in which the motion is transferred.
One LEGO gear is powering two LEGO Gears and at the end, from one motor we rotate two axles in opposite directions. Follow the building instructions.
A similar LEGO attachment the previous once, but this one is with a different gear ratio. Again using a frame, two axles and two gears you can change the direction of the motion.
Building instructions for a LEGO Mindstorms EV3 active attachment for changing gears orientations. This is the third attachment from the series.
