These are building instruction for a working automatic catapult with a motor and a touch sensor.
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!
This is a LEGO Mindstorms Boxing robot. The inspiration story goes like this "One day we though - Let's play SUMO at this robotics demonstration, but let's make it more interesting. Let's play sumo with Humanoid Robots". We decided to build a boxing robot. The goal of the robot is to press the touch sensor on the other robot and it could be very fun. Perfect robot for demonstration. It is controlled by a joystick using the Bluetooth connection.
Here are the joystick and the programs for the joystick and the robots.
Hrutur, from Icelandic, means Ram.
The robot is made to resemble a Ram. Its main focus are the gears, which make it go faster so that it can ram harder. It uses two Large EV3 motors to power the gear systems. At the front it has an Ultrasonic sensor for aesthetic purposes, which you can use however you like.
The GorillaBot walks on its two arms, using two large motors as forearms. It also has this awesome head, which actually is pretty useless as an ultrasonic sensor, unless you lift its eyebrows.
A turtle robot with 2 sensors- ultrasonic and gyro, capable of following her course and navigating through anything. Just don't annoy it, or it will hide in its shell or even come and bite you.
Maze Runners are one of the very popular robotics competitions. But there are a lot of limits that the robots must comply with. Like the size of the robot.
This here are building instructions for a very small maze runner robot, build with LEGO Mindstorms EV3. It uses two tires that are technic and not Mindstorms simply because none of the Mindstorms tires fit the size limit.
The robot has an Ultrasonic sensor and a Gyro sensor at the top.
Do you have some awesome remote controlled racer cars? Have you ever wanted to see which one is faster? Or maybe having a speed race with your homies. You can do all that and much more with this amazing LEGO Mindstorms EV3 radar robot. It will also ring police sirens when you break the speed limit, just know that you're declared WANTED!
An example program for using this robot could be found here.
The building instructions are for a robot that kind of looks like the Spy Bot but it has treads instead of wheels. Like a Tank. Tank Spy Bot. Treads are always funny and you could use the robot chassis base to extend with additional attachments and tools.
Building instructions for a Light LEGO Mindstorms EV3 Competition Robot that could be used in LEGO Robotics competitions. Compared with previous versions of this robot, this one has a Gyro Sensor.
Building instructions for LEGO EV3 catching robot. It uses a medium motor to drive system of gears, which is used for catching objects. It, also, has an ultrasonic and colour sensors for detecting the objects.
It moves and it collects. It collects objects.
These are building instructions for a LEGO Mindstorms robot that could collect objects. It is not actually catching them and that's why we call it "Simple Catch Bot". The general case is to program it to move on the floor and collect some of the Mindstorms wheels and tires coming with the 45544, 45560 or 31313 LEGO sets.
The kinesthetic and memory game works with a program you can download from here. In these instructions you will see the 7 modules from which it is built:
This robot is meant to be very modular and to enable its owner to upgrade it and modify it.
"Bot. Spy Bot."
Many of us are fascinated by the idea of spies. Movies for "spies" are also very popular and if you haven't watched them check out the 007 movies. These here are building instructions for a LEGO Mindstorms robot with two touch sensors and one ultrasonic. It could be used as a spy - sneaking closer to you and detecting if you move or if you touch it. The whole idea for this robot came from NXT when there were sound sensors. Currently, there are no sound sensors in the EV3 set, but the robot could again be quite fun to program.
This module is meant to be used in EV3 Kinesthetic and Memory Game and is attached to the base of the robot. This module uses the ultrasonic sensor to detect the hands of the player. Attention must be paid to where the module is attached since it can be activated by accident if the player reaches for another module over this one.
Building instructions for the One Attachment. Built from LEGO Mindstorms EV3 parts and with an Ultrasonic sensor we've used this attachment to accomplish most of the missions at FIRST LEGO League 2013.
SIngle robot attachment, many points.
Mintonette comes from the first iteration of Volleyball with the same name.
The robot uses two EV3 Touch sensors to control the turret left and right. It uses the EV3 Color sensor to trigger the shooting mechanism, which consists of an EV3 Large motor which pulls a lever to shoot a ball.
This is the robot that we use to demonstrate a solution for competition. This is a Post season solution. We never release any solutions during the season as this will have a negative impact on the competition. But after the competition we try to make a review and to see how we could have accomplish it. Our goal is to be better for next year.
This robot is quite powerful. The attachment mechanism on the front is one of a kind as it can do several things with a single motor: it can lift, it can unlock, it can grab. All of this thanks to the unique mechanism of gears
This frame holds the motor and ev3 brick used in the catapult. The frame is placed on top of the rotating base and thus could be easily rotated. The brick could be both NXT and EV3
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.
