This is an attachment for Kufar - Easy SPIKE Prime out-of-box robot. It is an experiment we did that didn't work out for the FLL 2023-2024 MASTERPIECE field, but is interesting nonetheless. It shows how you can take an out-of-box robot and put a steering mechanism on it.
This is an attachment for Kufar - Easy SPIKE Prime out-of-box robot. The attachment solves the light show mission using rubber bands! It works well, but it does depend on how new your model is. On newer models it can work with only 2 red rubber bands or even with 2 yellow and 2 red. Find the best combination for your field.
The trigger for the light show mechanism also releases Anna the Museum Curator and the masterpiece on the pedestal.
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.
A FIRST LEGO League 2023-2024 attachment for the MiniBox Robot.
This attachment is designed to detach, once it completes its purpose. This is done, so that the team loses less time switching attachments in the base, lowering the chance of human error during the competition.
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 attachment is accomplishing three missions from the FIRST LEGO League 2023-2024. It is for the Chain Monster Robot. It solve mission 11 - Light show. It partially solves mission 14 - Audience delivery.
A robot attachment placed on the right side of the LEGO Mindstorms Box robot chassis. It uses two gear wheel to move a level. The level could collect things.
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.
Attachment used to transfer the motion from the motor from a vertical axle to a horizontal axle. Uses two gear wheels. Could be built with LEGO Mindstorms EV3 and LEGO Mindstorms NXT kits.
Here is an example of Four(4) active LEGO Mindstorms attachments built-in the frame. Two by two they work asynchronously since all of them are connected to the two separate middle motors of the SUV robot via the frame.
The left attachments work synchronously, and the right attachments are also synchronized couple.
These specific attachments are meant to do nothing in particular, but to serve as an example. Their purpose is to demonstrate different ways in which one could add an attachments to the frame. Experiment. Think and invent better frame with real world attachments that could actually do efficient work and accomplish a mission. Take a video then and share it with us.
This robot attachment shows you how to limit the rotation of a lever. It uses two gear wheels to transfer the motion on 90 degrees.
It could be built with LEGO Mindstorms EV3 and NXT versions. Most of the time during competitions like FIRST LEGO League and World Robotics Olympiad you need a lever for just a limited motion
The goal of this robot attachment is to demonstrate a principle and example for lifting heavy objects vertically. It's built with LEGO Education SPIKE Prime parts and could be used in competitions in robotics like FIRST LEGO League/World Robotics Olympiad. It's designed for Luly, small LEGO Education SPIKE Prime competition robot with 3D building instructions. Check the courses in which this attachment is used for more information and tutorials on how to use it.
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
This is a robot attachment that could be used to lift object. The gear ratio of this attachment is allows it to lift Heavy objects. It's built with LEGO Education SPIKE Prime parts and could be used in competitions in robotics like FIRST LEGO League/World Robotics Olympiad. The goal of the attachment is to demonstrate the principle and example of an attachment for heavy lifting that could be placed on the robot. It's designed for Luly, small LEGO Education SPIKE Prime competition robot with 3D building instructions. Check the courses in which this attachment is used for more information and tutorials on how to use it.
We have to admit. This is quite an interesting missions. There is a Manhole cover and it must be turned upside down. Well, the robot must turn it. Again LEGO Box Robot Three With Large Wheels and Thee light sensors and one Gyro is used as a base for the Robot.
Lifter is an pretty fast and pretty strong attachment that lift up... things... like exercise machine, astronauts and other stuff.
A program for that attachment in Into Orbit 09 - Strength Exercise challenge is located at programs/hm9c06-lifter-an-attachment-for-suv-box-robot-and-into-orbits-m09-strength-exercise-program.
A simple active attachment that could be added to the Box Robot Chassis.
The central axle of the robot is most of the time the most important. The robot moves forward and does things with this axle. It is important to learn to you could extend such axles, and change the level and position of the extensions.
This is a LEGO Mindstorms EV3/NXT robot attachment.
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.
