With this attachment we just share an idea. The attachment was build by an FLL team called Brother in Arms and they needed a way to turn two axles in different direction, one at a time. The attachment was not used in the final robot design and construction, but presents a nice idea.
In this video we discuss part of the pinless attachments build by the ELM team. Without pinless attachment it is nearly impossible to achieve a good score at the FIRST LEGO League competition.
In this Episode, we stop at the pinless attachments for the Box Robot 2 and especially for the constructing a frame. This frame is then used for further extending the robot with 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
Two missions in one. This attachment accomplishes the Hydrodynamics Fountain and Faucet missions from the FIRST LEGO League Hydrodynamics 2017-2018 competitions. The attachment shows a really interesting and widely used approach of a single attachment that is used for two, three and even more missions. This is a standard practice for many of the advanced teams, especially those that reach the finals. The based of the robot is the LEGO Box Robot Three With Large Wheels and Thee light sensors and one Gyro
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
With this attachment we complete the Elevator and Steel construction for the FIRST LEGO League 2019-2020 competition. The attachment is placed on the Whakatae - LEGO Education SPIKE Prime Competition Box robot
Lifting a loop is one of the most common missions in different robotics competitions. In this video we demonstrate how we could do "Vertical lift". It is suitable for precise lifting especially when the mission model requires you to lift straight up. The robot attachment could be adapted to other missions at FIRST LEGO League/World Robotics Olympiad and other robotics competitions that require push/pull. The principle is the same. The tutorial uses Luly, a small LEGO Education SPIKE Prime competition robot with 3D building instructions as a robot base.
This is a LEGO Education SPIKE Prime robot attachment for accomplishing the FIRST LEGO League 2020 Replay Weight Machine mission . The attachment is designed for Gazon, LEGO Education SPIKE Prime competition robot.
This is a robot attachment built only with parts from LEGO Mindstorms Robot Inventor Set. The goal of the attachment is to accomplish the FIRST LEGO League 2020 RePlay mission call Treadmill. The attachment has two gear wheels that could transfer the power from the motors to the wheel. The wheel is the one that is accomplishing the mission as it rotates and rotates. The attachment is pinless.
This attachment is a demonstration of how easy to detach attachment could be build for LEGO MINDSTORMS Robot Inventor robot where both the robot and the attachment is from the same 51515 set. The principle is useful for accomplishing missions where the mission model should be placed on the FIRST LEGO League field and in the same time should be supported in a way. Check out the tutorial for a demonstration.
This attachment demonstrates pushing and pulling with a circular motion. It is useful for FIRST LEGO League competitions where you can grad a mission model and bring it back to base or push/pull on a lever.
In this video tutorial we accomplish the Cell Phone mission from the FIRST LEGO League robotics competition, season 2020-2021. The goal of the mission is to flip a phone. There were a couple of missions in the past with one important mission in 2017 that was very similar. It is a 10 out of 10 tutorial which means we accomplish the cell phone mission every time.
This video tutorial is for the Tire Flip Mission from FIRST LEGO League 2020 RePlay robotics competition. Flip missions are always some of the most interesting and challenging. In this tutorial you would learn how to build an attachment and accomplish a mission that requires you to flip a part, like flipping a coin. Most of the complexity for this mission is in the attachment and not the programming, but this is also way it works perfectly, every single time.
This is a recording of a completely perfect, 10 out of 10 accomplishment of a two-part mission - Train tracks, from the FIRST LEGO League 2021-2022 Cargo Connect competition. Due to the proper use of motion and color/light sensors, the robot is 100% consistent and reliable for a non-trivial mission. Even when the robot makes a mistake, it auto-corrects and compensates for this mistake.
"Sometimes it works, sometimes it does not work" - this is the most common case in FIRST LEGO League competitions. In this tutorial, we demonstrate and discuss such a case where the first part of accomplishing the mission always works but the second part has about 60-70% success rate. The robot is not very consistent. Let's take a moment to see it and explain why so that we can resolve the problem in the next lesson.
These are 3D building instructions for an extensible and configurable attachment for FIRST LEGO League 2021 Cargo Connect and the Sorting Center mission. The attachment has 3 axles, and we can place these axles in all kinds of configurations.
In this LEGO video tutorial we accomplish 3 missions with the Kriket box robot. A number of actions are performed like Lever, Lift, Drop, Pull, Align. This tutorials shows how to accomplish missions models that are closely positioned next to each other.
This 10 out of 10 tutorial is a complete uncut recording and it shows how the Chain Monster box robot accomplishes 5 missions in a single run and it does this 10 out of 10 times. It is from the FIRST LEGO League 2022-2023 robotics competition.
