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.
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.
Building instructions for a safe mechanism. The medium motor can be used for dialing in the key lock. The brick buttons can also be used for a pin code input.
One of the large motors unlocks the latch, the other one opens up the lid of the safe.
Sebastian is a six-legged creature, which technically makes it not-a-crab. Anyway, it still walks sideways and is amazing to build and watch.
You can find the program for Sebastian here.
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.
This robot was designed for the VEX IQ Challenge 2019-2020. It could push four hubs simultaneously. It can carry one. And it call pull itself on the bar at the end of the run. We've used four omni wheels of which the two at the back are the driving wheels.
Demo program can be found at Program for Winner - VEX IQ Competition Robot for the 2018-2019 Challenge.
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".
A phone holder that rings an alarm when the phone is picked up. It is a plate, lying on a rubber wheel, that changes its height, based on the weight of the object placed on top. The color sensor detects these changes and rings the alarm. With some fine tuning, this robot can even act as a weighing machine.
Big Wheelster, as his name suggests, is a robot with a big wheel! The Big Wheel is made out of the SPIKE Prime Baseplates. The robot also has an interesting steering mechanism! At the front we have added a touch sensor, to detect an obstacle and hopefully avoid it.
Geldautomaat, from German, means ATM.
This is the last robot from the 3.0 course book in the LEGO Mindstorms Curriculum. It uses a Touch Sensor to sense if there is a card inside. When touched, a Medium Motor starts spinning and pulls the card inside its chamber, where a Color Sensor reads the data from the card.
NOTE: There is a step, where you have to place the "credit card" inside. It may seem unnecessary and pointless, but otherwise, you will not have proper support for the next steps and the construction will crumble.
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!
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
