Alice, the rooster robot, built with LEGO Mindstorms EV3
Alice is a lovely little bird, with some amazing mechanisms on her feet. It uses two large motors and one medium one as a head, which drives both its wings.

This is an 8 bar lifting robot. Way should I build this instead of Roberto bot you ask? Because it is... well... it lift thing straight up, it lift 'em higher, it's more beautiful than Roberto and is more bad ass looking than 4 bar lifting mechanism. OOoohhh, and one more thing it may use the same program as Roberto Bot With Four Bars Lifting Mechanism.

In all building instructions for LEGO robots it is important to have the motors attached to the brick in more than one place. In the following construction, there is a beam connecting the two motors which has exactly this purpose. It makes the construction much more stable. Try removing this beam for example and see what will happen. Would the robot be able to move?
Many different types of wheels could be used. Both NXT and EV3 or from other LEGO technic series.
Building instructions for a LEGO Mindstorms EV3 robot where the motors are at the back of the horizontally placed brick and they are placed vertically. This construction is difficult to turn with but at the same time is quite high and could be used as a base for different trucks or animals.
Our Lander doesn’t have working parachutes, thrusters, or cushions, but one important feature is realistic … it’s very fragile.
Get the lander to one of its targets intact, or at least get it to base.

This WRO robot is designed to collect a lot of ping pong balls in its container. It's built with LEGO Mindstorms EV3 45544 and 45560 sets. These are the LEGO Educational sets. The robot has two chains that collect the balls and push them into the container attachment. This is one of the larges robots we've uploaded at FLLCasts yet. You could learn a lot by following the building instructions and paying attention to the details of how this robot is built. All the alignment, all the connections. Really beautiful.
Robot for collecting ping pong balls used in the World Robotics Olympiad competitions. It is constructed with LEGO Mindstorms EV3

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.
This is the forth type of an active geared attachment. "Active" means that is is power by a motor. "Geared" means that it uses gears. "Reusable" means that you can easily extend the attachment with additional parts - eg - you can reuse it. It shows a basic principle of how power is transferred between different axles that have different orientation in space - like when one of the axles is horizontal and the other is vertical. It's built with LEGO Education SPIKE Prime parts and could be used in competitions in robotics like FIRST LEGO League/World Robotics Olympiad and others. 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.
Pallo, from ancient Greek, means to throw or to hurl, which is a part of the modern name "catapult".
Pallo is a robot made of two parts. The first part of the robot is the catapult! It has no electronic parts and uses two rubber bands to shoot a projectile to the second part. The second part is the target. It has a color sensor, which through a piston with different colored sections, determines how accurately the target has been hit! Good luck with the shooting!
This robot is made to serve the best tea in the whole continent! It is based on the Easy Bot from EV3. As its predecessor it is based on LEGO Mindstorms EV3. It uses two large motors to move around. The best part of the robot is the cup holder, that has a cool cup that shows the KISS principle.
These are instructions on how to build the:

This robot attachment in inspired by one of the most interesting missions we've seen at FIRST LEGO League competitions - the Manhole Cover (08th) Mission in FIRST LEGO League 2017-2018 . The attachment demonstrates how you could flip an object. 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.

This is an pinless robot attachment designed for taking loops. It's built with LEGO Education SPIKE Prime parts and it demonstrates how to collect a loop while moving with the robot. The attachment is designed for Luly, small LEGO Education SPIKE Prime competition robot with 3D building instructions. There are other attachment that are designed for taking a loop and locking it so that it does not fall, but they are more complex. Search for 'Carabiner' at FLLCasts.com
This is the attachment of Team "Nightbeast", with which they solve M01 and M02 from FLL Into Orbit Challenge
