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.
This short animation demonstrates a really useful principle for FIRST LEGO League competition and this is how to use the Inertia of the robot to trigger an attachment that will do the work for us. It is very useful as we don't have to use the motors of the robot and we can afford to use the motors for other things.
In this video tutorial we continue the exploration of pinless attachments and how to add them and remove them in a quick fashion. We've done this for SPIKE Prime and for EV3 and we will provide some other references in the lesson in the course. The idea of an attachment below the robot is that sometime, during FIRST LEGO League competitions we have to bring a mission model from one place of the field to other. Basically push it.
This animation demonstrates a vertical lift attachment. This is an attachment that transfer a circular motion from the motors to a linear motion and is a very powerful concept. We demonstrate it with a LEGO MINDSTORMS Robot Inventor robot build from 51515 set. This is arguably one of the most complex attachments in this course.
This video tutorial had a different idea than what we recorded. We planned for a push/pull attachment as we've shown such attachments for LEGO Education SPIKE PRIME and LEGO MINDSTORMS EV3. However, the issues with LEGO MINDSTORMS Robot Inventor set 51515 is that we could not figure out an easy way to build a push pull attachment that meets our criteria for an attachment. Because of this we made a slight modification on the idea and it is again push/pull attachment but not moving in a line but in a circle - circular movement.
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.
No need for all attachments to be powered by motors and to include gears. It's sometimes possible to use a simple robot attachment to collect objects. Such attachments we call passive and this one is an example for the Box Robot Chassis.
Build with LEGO Mindstorms EV3
Frame for adding attachments on the robot. When using a frame it is very easy to quickly add and remove pinless attachments from the robot. The whole frame could be removed.
The frame contains parts from LEGO Mindstorms EV3.
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.
The first of a series of attachments that we add to a World Robotics Olympiad LEGO Mindstorms Robot. The attachment is an example for collecting ping-balls. The robot and the attachment are in the same construction. The attachment is a base for a container that could be extended.
Attachment part of a series of robot attachments for accomplishing the FIRST LEGO League 2013 competition. This specific construction lifts the two vehicles. It uses rubber bands for locking the levers. Take a look at the video tutorials for details explanation on how it works.
Build from LEGO Mindstorms EV3 parts.
Instructions for building the quick attachments for this LEGO robot
Here is another great example of a large multi-purpose attachment used in FIRST LEGO League competitions. This one is specifically for the 2017-2018 Hydrodynamics competitions and is doing a number of missions. (01) Pipe removal, (06) Water Treatment and (08) Manhole cover.
The attachment consists of two parts. The first part is placed on the robot while the second part is in front of the robot and the robot pushes it. While working on the field the robot leaves the second part on the Water Treatment plant and when returning back collects it back and returns to base.
The goal of the attachment is for you to build it and experiment with it with the existing field. Use Box Robot 2 as a robot base on which to add the 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.
Meet Kiddo, smaller sister of Roller Coaster. It is smaller, easier to build and easier to control box robot with X-Y moving plate.
The goal of this robot is to have one complex attachment that could move in four directions. With such an attachment you can solve a lot of complex tasks without loosing time changing attachments. It is also quite sturdy and packed
