Building Instructions

This is a simple pinless active attachment for the SUV Box Robot.

In this attachment we use "(32498) Technic Gear 36 Tooth Double Bevel". There are four pins added to the wheel and it it this pins that engage with the "(32072 ) Technic Gear 4 Knob". The more important thing is that the knob wheel and the gear wheel are parallel to each other.

While the motor rotates the attachment has 4 points of contact (instead of one or two when two Knob Wheels are in contact) with the robot knob wheel. There are no forces that drive the attachment to jump and lose engagement with the robot.

This is a self aligning passive attachment for rendezvous and meeting between the tube module and the habitation hub.

The program for this attachment is Self Aligning Module Attacher for M06 - Space Station Modules.

There is another program at Self Aligning Module Attacher for M06 - Space Station Modules - another program.

Building instructions for the One Attachment. Built from LEGO Mindstorms EV3 parts and with an Ultrasonic sensor we've used this attachment to accomplish most of the missions at FIRST LEGO League 2013.

SIngle robot attachment, many points. 

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. 

The attachment shows how to do build a pinless robot attachment with LEGO EV3 Mindstorms.
