How to build a 3D LEGO Mindstorms Model using LDraw (part 2)
In the first part we built our first 3D LEGO model. Today we will smooth the model we have created and go through the process of creating PDF instructions for building it.

Importance of the caster ball on the LEGO Mindstorms robot movement
You could use the LEGO Steel Balls as a third wheel on the robot. It is a caster wheel. But this is steel and as we know from basic existence on this planet, where there is steel there is also rust. The steel ball could get quite rusty and this could have an influence on the behaviour of the robot

FLL 2020: How to accomplish the Rowing Machine mission with LEGO MIndstorms Robot Inventor
This video tutorial demonstrated the use of an active gear attachment for catching a wheel and pulling it. This is how we accomplish the Rowing Mission from the FIRST LEGO League 2021 competition. What you will learn is how such an attachment works. How you transfer power from the top of the robot where the motors are to the bottom of the robot where the catching mechanism is. Check out the building instructions for the attachment.

FLL 2020: 10 out of 10 on how to accomplish the Treadmill mission with LEGO Mindstorms Robot Inventor
This is a 10 out of 10 tutorial demonstrating the accuracy of an active gear attachment that accomplishes the Treadmill mission from the FIRST LEGO League 2020 RePlay competition. When the robot is well aligned to the line before that it is easy for the robot to accomplish the mission. You will see how we make use of the friction of the wheel to rotate the mission model.

Accelerate and Decelerate with LEGO MINDSTORMS Robot Inventor
In this video tutorial we are demonstrating the impact of slow and fast acceleration on the robot. In the Scratch program there is an acceleration block for fast and slow acceleration. The robot behaves in different way. Let's explore them so that you know what to use for FIRST LEGO League competitions.

Talus - Simple Side Attachment LEGO Mindstorms Robot
There are so many ways to attach the motor to a Mindstorms Brick. We haven't counted them, but we sure like to experiment with them. This is one way. Not the perfect, not very stable sometimes, but you could also learn from prototypes and "mistakes". And the LEGO brick is on the same level as the motors. Follow the building constructions and have the motors attached to the sides of this Mindstorms Base construction.

Midas - a LEGO Mindstorms EV3 Clam robot
The robot uses two Large Mindstorms EV3 Motors to open and close its shell. On the top of the shell are used four hoses, that can be reshaped to form different shell styles. It also uses two black bent beams for eyebrows, that can be moved to change the expression of the clam. A Castor Ball is used to represent its pearl.

Demogorgon - Upside Down robot with LEGO Mindstorms
This here is a base for a robot that has the brick Upside Down. Have you seen Stranger Things? We would admit that this robot does not look exactly like a 'Demogorgon', but this here is the challenge. Can you use this base and make the robot look like a Demogorgon. Add a picture to the comments section below the material.
Do you have other ideas for Demogorgon? Build them with LEGO and add a picture below this material or send it to [email protected]. We would feature it at FLLCasts.com.

Guard Tank - Simple LEGO Mindstorms Robot with treads
Let's build a robot with treads. These building instructions are for a Guard Tank Robot. The good thing about tanks is that they could tackle a lot of obstacles on their way. At least this is what people are saying. Try it. Could you move over LEGO parts with this tank if they are one brick tall, or two bricks tall? What would be the largest obstacle that you could find, over which this tank could still move? Share a video or picture below in the comments section.
We would admit that this tank lacks a gun or an arm, but it is up to you to build one.

Anty - LEGO Mindstorms Robot that behaves like an ant
Again a LEGO animal. This time it looks like an ant. It's interesting that this robot has no wheels and moves in a way very different from the rest of the "wheel robots".
There is much to be learned about mechanics from the way animals move. Ants are a good example. In the real world, an ant could carry a load of 20x its mass. It would be interesting to see how much load could this robot carry? Try it.
