Quick Pinless Attachments for LEGO EV3 Competition Robots (Part 2)

If you think that the quick pinless attachments shown in video 63 are quick enough, see this tutorial and you will find out that the quick pinless attachments could be even quicker. These attachments can work without motors but by using the inertia forces.

This tutorial shows the logic of creating quick pinless attachments which do not have any moving parts. This facilitates their placement and is the key to the quicker change of attachments on the LEGO Mindstorms robot construction.

There is a short description of how the attachments work; how the inertia forces affect the robot parts and what causes these inertia forces. The tutorial once again focuses on the building process of the quick pinless construction base, the attachment and the adaptor.

Try to use this type of quick pinless attachments and see how many new opportunities it will give you. Share with us your comments and ideas.

Quick Pinless attachments on a robot

This tutorial shows how quick pinless attachment collects loops. Such attachments are popular at the FIRST LEGO League competition. The attachment uses Luly, a small LEGO Education SPIKE Prime competition robot with 3D building instructions as a robot base.

Inertia triggered attachment for collect

Inertia triggered attachments does no require the use of a motor. Let the inertia do all the work. These kinds of attachments are very useful at robotics competitions like FIRST LEGO League and World Robot Olympiad. The robot moves, the attachment falls and grabs the ball. The attachment uses Luly, a small LEGO Education SPIKE Prime competition robot with 3D building instructions as a robot base.
