Building Instructions

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.

Instructions for building remote control. It uses the rotation sensor to determine the steering and touch sensor for handling the movement. Find building instructions for a suitable chassis here. 

Together the controller and the car look like this:

Building instructions for the most simple grabber using just one Large EV3 LEGO motor. It has one static lever and one active lever.

This is version 2 of the LEGO Mindstorms Grabber. It makes use of 4 gears to make both levers active.  

This is the third version of the LEGO Mindstorms Grabber. This time we use a LEGO EV3 Medium motor and worm gear to make the two levers move smoothly and symmetrically.

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. 

Building instructions for a LEGO Mindstorms EV3 robot that could be completed in about 3 minutes. Could you do it? Try it. 

We use this robot when we need something very fast for a demonstration or a small competition. Just attach the motors and you are ready. It is fast.

Building instructions for the catapult that could be placed over the LEGO Mindstorms EV3 Brick. The idea of the catapult it to throw objects. The fact that it is over the brick makes it very convenient to place the motors below the brick and to use the Catapult. 

This robot construction itself was used in the FIRST LEGO League Senior Solutions competition

Advanced LEGO MINDSTORMS EV3 Construction. It has two rear motors and it could rotate the whole from part. It has 4 wheels and is kind of like unique in the Mindstorms world.

Building instructions are not very easy and you need LEGO Education Core and Extension Sets - 45544 and 45560. 

Apart from being advanced, it is also quite fun to try to build.

Building instructions for this part of the BigDaddy competition robot

These are building instruction for a working automatic catapult with a motor and a touch sensor.

This is the initial construction of a catapult. The base on which we will place the rest of the robot. The goal of this construction is to give the catapult the ability to rotate.

This frame holds the motor and ev3 brick used in the catapult. The frame is placed on top of the rotating base and thus could be easily rotated. The brick could be both NXT and EV3

The rotation frame requiers an NXT large double gear wheel that is not available at the EV3 set. You can use the instructions below to construct a similar mechanism from Mindstorms EV3 set

Building instruction for both EV3 and NXT. The whole catapult is build in exactly 78 steps.
