We had a couple of minutes before starting another robot and we just came up with this robot. If you would like to build a Box Robot, but don't have enough parts this is a good construction that you could learn from. It has a frame. It has three motors. You can add attachments at the top.
This is the simplest possible line following robot. It has just one sensor in the front between the two driving wheels and uses beams as pivots instead of a third wheel. Try it out. Follow the building instructions and start following lines in a number of minutes.
Don't we all love animals? But it is sometimes difficult to have a puppy at home. Presenting to you - the Puppy robot (drums in the back). It has some of the benefits of a Puppy - it is small, it can follow you with the Ultrasonic Sensor and it can bark (if you program it to). Follow the building instructions. Use it at home or at class.
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.
A nice little robot that can tell if there is anything on top of it. It only uses one touch sensor. The idea of the robot is to be used in classes with students to explore different interesting security options. This robot in particular could detect when the object placed on it gets "stollen". Have you ever watched Indiana Jones? :)
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".
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.
WatchTower is a pretty self-explanatory robot. It detects intruders by sensing the vibrations they make while walking or digging beneath it. For this purpose, it uses a Gyro sensor, which could be incredibly sensitive under the right circumstances. The Ultrasonic sensor that sits on top of a medium motor starts locating the intruders when the Gyro sensor detects them.
Lintu means bird in finnish.
The robot is made to resemble a Kiwi bird, an endangered species of flightless birds, found only in New Zealand.
Lintu uses two large motors as legs. They are placed at an angle so that they resemble the strange posture of the kiwi bird.
The beak of the robot uses an interesting mechanism to open and close utilizing two technic steering links and a medium motor. For eyes, the robot uses an Ultrasonic sensor.
Susan comes from Sue, which is the name of the largest fully preserved specimen of T-Rexes.
Mark comes from Marc Bolan, who is the lead singer/gutarist of the band T-Rex.
The robot is made to resemble a T-Rex (Susan) chasing a car (Mark).
The T-Rex uses a Large motor to go forward and backward. The other Large motor is used for the car, which resembles a very simple 4-wheel vechicle. Susan's task is to spot Mark using the current power option of the motor rotation sensor. As T-Rexes can not notice you if you are moving very slow, Mark is trying his best to move really slow so that he doesn't get spotted!
Remilo comes from esperanto and means paddle.
The robot resembles a boat, but moves on land. It uses two large motors with "paddles" attached to them to move. Because its movement capabilities are limited, it has a gyro sensor to correctly move forward.
Gen comes from Gendema, a bulgarian late 80s rock band, popular with its song about pedalos.
The robot uses two EV3 Large motors to move, but instead of wheels it uses four-legged paddles, attached to the motors. This makes it look like a pedalo. Additionally it slides on the ground much like a real pedalo on the water.
Because of the strange mechanism of movement, the robot has a gyro sensor to help it keep a straight line.
The Laboratory is a robot that tests your programming skills. You will have to measure the volume of a balloon, only by the values you receive from the sensors.
It has a valve, that allows you to deflate your balloon at different rates.
How to place the balloon in the robot is explained in this tutorial.
Barco from spanish means boat.
The robot is made to look like a sail ship. The sails are made out of technic panels, attached in various ways to create the best look. Otherwise the robot uses two motors with tyres to move. At the back of the robot there is a Gyro sensor, which helps it maneuver.
Uylam is a robot that simulates a stormy environment for its ship. It is made using two piston-like mechanisms powered by a Large motor and offset by 90 degrees to create shaking similar to that of big waves. The ship itself is made out of a medium motor on a turntable and a gyro sensor attached to them. The purpose of this is to explore what is the best position of a ship compared to the waves, so that it sustains the least amount of shaking.
