Piscis from Latin means fish.

Piscis is a LEGO fish robot which uses a very interesting mechanism for turning. It's tail uses a medium motor to turn left or right. On its end there are two wheels. When the robot turns its tail, those wheels navigate the movement of the robot and it turns. This results in a cool turning mechanism which resembles how fish move.

Piscis also uses a large motor to move forward and backward. The touch sensor at the front helps it sense danger and return quickly back to the reef.

Watch out for the tooth wheels, they bite!

Antares is the brightest star in the Scorpius constellation.

The robot's main purpose is to show two different grabbing mechanisms - one vertical and one horizontal. The vertical pincers use a medium motor and the horizontal pincers use a large motor. Additionally the robot has a sting mechanism which uses another large motor. For a head it uses an EV3 ultrasonic sensor. With the sensor, the robot can sense when the prey is close enough for a suprise attack.

This is a version of the Midas - a LEGO Mindstorms EV3 Clam robot. The main difference between the two robots is that the motors are flipped. 

The robot uses two Large Mindstorms EV3 Motors to open and close its shell. There are four hoses on the top of the shell which can be reshaped to form different shell styles. It also uses two black bent beams for eyebrows that can be moved to change the expression of the clam. A Castor Ball is used to represent its pearl.

Larvy is a SPIKE Prime robot, that moves like a larva or caterpillar. The robot has a Large motor, that contracts and expands it! Using the two medium motors, it turns 4 tyres to their side and upright whenever it wants, so that it can move forward!

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

Tohuru, from Maori, means owl.

Tohuru is a SPIKE Prime robot, that holds onto an edge and looks at the nearest object! It uses two medium motors to grip an edge between two wheels. In addition it has a head made out of an ultrasonic sensor, attached to a large motor, which allows it to turn 360 degrees! And most importantly, it looks like an Owl!

Cápa means shark in Hungarian.

The robot resembles a live hammershark. It uses a medium motor to move its tail, which is used for the shark to turn. It moves forward with a large motor and two tyres. Its jaws open and close with a second large motor. The two touch sensors at the front are purely for aesthetics but you can use them if you like. Finally the head has an ultrasonic sensor which detects if something is a potential "prey". This resembles the real hammer sharks' ability to sense with their "hammer".

The robot uses two Large Mindstorms EV3 Motors to open and close its shell. On the top of the shell are used four hoses, that can be reshaped to form different shell styles. It also uses two black bent beams for eyebrows, that can be moved to change the expression of the clam. A Castor Ball is used to represent its pearl.
