SUV Front Active Attachment for Box Robot

This attachment uses a connector ("(98585) Technic Connector Circular With 2 Pin Holes and 3 Axle Holes") with 4 pins to connect with a knob wheel ("(32072 ) Technic Gear 4 Knob") of the robot. Because both elements are parallel one to another there is no jumping effect.

The attachment uses two pins, but it is easy to attach and detach because it uses "(6558) Technic Pin Long with Friction and Slot". When you attach or detach the attachment the slots are keeping the pins strong on to the attachment.

Also an attachment connected to the robot in this way, can be move to the rigth knob wheel or to the left knob wheel.

SUV Box Robot for Robotics Competitions

After the great success of the previous two Box Robots Courses (Box Robot 1 and Box Robot 2) we are improving the construction even further showing one more way to build Box Robots and to resolve some of the challenges that we all had with the previous robots.

Of course attachments are a great topic of the robots. We show the general way in which one is to build attachments with the Knob Wheels and Gear Wheels mechanisms.

Robot Attachments

In this attachment two knob wheels "(32072 ) Technic Gear 4 Knob" engage at 90 degrees angle. One of the knob wheels is a part of the robot and the other is a part of a pinless active attachment. The purpose of this attachment is to demonstrate How NOT to build attachments.

Build the attachment and experiment. See for yourself how it "jumps" up and down when the knob wheels are rotating and you hold the lever by hand.

FLLCasts Off-season Challenge with LEGO Mindstorms EV3

The FLL season is great, but has one disadvantage - it ends. We have prepared that course for those of you that does not want to stop! The course presents a whole new challenge with custom designed field and mission models, that can be built from just 2 LEGO Mindstorms EV3 sets (core+resource). It is a great way to keep the momentum going after the end of the FLL season and prepare in the best way possible for the next.

(In development) How to design an active attachment

Introduction

Now, we will learn about how to build a proper active attachment. Building active attachments is essential for every successful team. Today we will build two such attachments and try to solve the Power supply mission with each of them. We will compare the attachments and learn some of the best practices when building such an attachment.
