This is a module that looks like a fish's head. It uses a touch sensor for a mouth and is otherwise purely cosmetic. The module is used in Piscis - a LEGO Mindstorms EV3 Fish robot.

This module is made to look and move like a real ship's sails! The module consists of two masts that are connected so that they move together. The back mast is connected to a medium motor that can move all sails and is also connected to a gyro sensor, that can detect if the whole ship is rotated. This module is used in Yolanda - LEGO Mindstorms EV3 Sailship robot.

This is a module that is made to look like a mantis' pincers and head. The pincers are powered by a medium motor and the head has an ultrasonic sensor for eyes. This module is used in Mantissa, a LEGO Mindstorms EV3 mantis robot.

This is a cool scissor mechanism that looks like the sting of a scorpion. It is powered by a medium motor and at the top there is a touch sensor, to detect if something has been stung! The sting is used in Scorpion - LEGO EV3 Robot.

This module is made to look like a head of a ram made with LEGO Mindstorms EV3. It uses an ultrasonic sensor, which points down as if it is going to attack, as the eyes of the head. It can be combined with other modules to create the perfect ram robot!

This is a mechanical cannon that uses the mechanical strain on the plastic LEGO beams to shoot a ball. Because of that the Ball size is very important. It is made to work with standard balls for a ball pool and even better with 41250 52mm LEGO Ball. The mechanism is powered by an EV3 Large motor.

This is a robot, designed to easily lift a cup, while still holding it upright. The robot uses one motor attached to the brick to lift the cup to any angle you want. The cup we have added is purely cosmetic, but with a few adjustments, you can make it lift real cups. Be careful around liquids though!

Chronos means time in Greek.

What's the time? Time to build a cool robot! This robot is made to look like a clock. The two hands are each connected to a motor and are positioned between the two motors. This makes it simple to build, while also being effective in showing how a clock works.

An example program moving the seconds and minutes hands of the clock can be found here.

An example program designed to teach children to read the clock can be found here.

Motivated by the five-minute robot, this robot has its own rails!

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

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!

Big Wheelster, as the name suggests, is a robot with a big wheel! The large wheel is built using SPIKE Prime baseplates. The robot also features an interesting steering mechanism. At the front, we’ve added a touch sensor to detect obstacles—and hopefully avoid them!

Tohuru, from Māori, means owl.

Tohuru is a SPIKE Prime robot that grips onto an edge and scans for the nearest object! It uses two Medium Motors to hold onto an edge between its wheels. Its head—made from an Ultrasonic Sensor—is mounted on a Large Motor, allowing it to rotate a full 360 degrees. And most importantly, it looks just like an owl!

Calix comes from Latin, meaning cup.

Calix is a robot designed to carry small objects—like a cup—while autonomously following a black line. When most people think about robotics, they imagine machines helping with household chores. Calix is a simple example of that vision brought to life. You can place a cup on it in the kitchen, and it will deliver the cup to the end of the black line!

The robot is powered by two SPIKE Prime medium motors for movement, and it uses a color sensor to follow the line precisely. At the front, a large motor connected to a gear system lifts and lowers the cup, allowing for easy pickup and delivery.

Calix is an elegant demonstration of how even simple robots can be designed to perform useful tasks—making robotics more approachable and practical for everyday life.
