Calix, from latin, means cup. Calix is made to carry an object while following a black line. Most people, when they think of robotics, they think of how the robots may help them at home, with the chores that no one wants to do. This robot is a simple version of this. You can give it a cup in the kitchen and then it will deliver it to the end of the black line! The robot uses two SPIKE Prime medium motors to move and a color sensor to follow a line. At the front it has Large motor with a gear system that lowers and rises the "cup".

The Swing Game is a SPIKE Prime robot designed as a two-player game. The goal is for both LEGO figures to reach the center of the swing without tipping it over to either side. Each LEGO figure is mounted on a motor connected to a Technic gear rack, allowing it to move along the swing. The motors are controlled separately—one by a color sensor and the other by a Large Motor. If one player moves too far ahead without the other keeping up, the swing will tip... and it’s game over! Good luck, and have fun!

Larvy is a SPIKE Prime robot that moves like a larva or caterpillar. It uses a Large Motor to contract and expand its body, mimicking the crawling motion.

Using two Medium Motors, it rotates four wheels - tilting them sideways or upright as needed - so it can move forward!

A program for the robot can be found here: Program for Larvy - LEGO SPIKE Prime robot

Francesco 2 is inspired by the robot Francesco.

Building instructions for a simple car using an EV3 Large motor for turning the front wheels and EV3 medium motor with differential for driving the rear wheels. Differently, from Francesco, Francesco 2 has space where a locking mechanism is meant to be built for the differential.

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.

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.

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.

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
