Rubber bands, gear wheels and motors for solving FLL 2013 Truck and Ambulance (part 1)
With this series of videos we are looking at FIRST LEGO League 2013 Nature's Fury competition and we are building a robot for accomplishing some of the mission. It would be a tutorial with at least four parts and we are building a complex attachment that could catch, lift and release different parts with only one motor and rubber bands. Not one, not two, but three movements with only one motor.

Active attachment for changing gears direction - part 3: moving up&down
In this video lesson I am building a LEGO Mindstorms EV3 active attachment powered by a small gear wheel. The attachment could move up and down, it is very useful for collecting objects. It could easily be adapted and used on other robots.
We are making a parallel with Video Lesson 56 from the series and we are also showing ways to improve the stability of an axle which is most of the time neglected, but could lead to great problems.

Idat Bot - Sturdy Motor Attachment of Motors for LEGO Mindstorms EV3 Robot
Not all LEGO Mindstorms EV3 Robot should be aligned horizontally or vertically. It is quite possible to have the brick and the motors attached in such a way that the robot is at a certain angle.
This is a very useful small construction that could be used as a base and extended with hands and heads or other interesting ....robot body parts.

Famulus - LEGO SPIKE Prime robot
Famulus means waiter in Latin.
One pumpkin spice latte coming right up! This robot is made to serve the best drinks in the whole continent! It is one of the simpler robots that can be made with the LEGO SPIKE Prime set and it uses two medium motors to move around. The coolest part about the robot is the cup holder where a "cup" can be attached or removed. Bottoms up!
