Piscis - a LEGO Mindstorms EV3 Fish robot

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!

Courses and lessons with this Material

This Material is used in the following courses and lessons

Level D1. "Animals". Robotics with LEGO

This is the seventh level of the Robotics with LEGO curriculum for students in third or fourth grade.

In this level students focus on the rotational sensor that is part of every motor in the robotics set.
Robot constructions imitate animals and their behavior. Students create programs that check whether the robot's claws or pecks have successfully caught an object. That sensor in the motors allows the robots to go back in their lairs even after the use of unlimited movement.

Lesson 2 - Fish

Introduction

In this lesson we are going to build a fish robot.
Have you ever been fishing? Have you seen live fish? Where?

Just like the fish on the picture, today’s robot lives in a coral reef. As many other fish live safely in the coral reef, just like ours, there is not much food left there. Therefore, our task today will be to help the fish robot search the region around its home and find some food.

Robotics with LEGO - Level 2.5 - Maritime Journey

The fourth level of the Robotics with LEGO curriculum for students from fifth to twelfth grades.

In this level students focus on the rotational sensor that is part of every motor in the robotics set. Students also learn to use the fourth sensor in the robotics set - the gyro sensor.
First few robot constructions imitate sea-animals and their behavior. Students create programs that check whether the robot's claws or pecks have successfully caught an object. That sensor in the motors allows the robots to go back in their lairs even after the use of unlimited movement. The rest of the robots are modeled after boats, yachts, and ships. With the help of the gyro sensor, students can set a course for their robots to a given angle and can detect deviations from the course. In open seas, there may be sea-monsters and the robots are being programmed to detect a sudden change in acceleration with the help of the said sensor.
