For the FIRST LEGO League 2016-2017 Animal Allies we prepared an attachment for lifting the robot. The idea of the attachment is to show how you could lift the whole robot with a system of gear wheels, levers, and scissors constructions.
Built mainly from LEGO Mindstorms EV3 parts but could probably be constructed from NXT sets.
This LEGO Mindstorms robot base is small, compact and packed in a very small volume. The goal of this constructions is to be used as a base and to show yet another way to experiment with adding motors to the brick.
LEGO Mindstorms EV3 Robot designed for a Folk Race competition. This robot has three Ultrasonic Sensors. Follow the building instructions and at the end, you would have a very basic robot with tank treads that you could directly use.
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.
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.
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.
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.
This one is also fast. It has assistant wheels, but only to keep the balance. It is built with LEGO Mindstorms EV3 sets with the use of one additional Medium Motor.
Join the course A robot a "day" keeps the questions awake where we will further discuss the motors, how to build them and what tasks to accomplish with them.
In all building instructions for LEGO robots it is important to have the motors attached to the brick in more than one place. In the following construction, there is a beam connecting the two motors which has exactly this purpose. It makes the construction much more stable. Try removing this beam for example and see what will happen. Would the robot be able to move?
Many different types of wheels could be used. Both NXT and EV3 or from other LEGO technic series.
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.
"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.
Vex IQ robot base which could be used with different attachments. The gravity center of this robot is in the backside and it has a lot of space in front for attachments.
VEX IQ version of an Easy Bot. It's simple and appropriate for classes of students.
These are buliding instructions for the FTC robot and collecting attachments with it. We are doing small modifications of the push bot.
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.
Building instructions for the robot build with LEGO Mindstorms EV3. It is called "Frankenstein" because the two motors are in two different directions.
It's the second version of the Robot Base 4, but with rotated inside motor.
Building instructions with dimensions on the ball collecting mechanism for the FIRST Technical Challenge Push Bot. The collecting mechanism should be attached to the Chassis - https://www.fllcasts.com/materials/382-ftc-push-bot-chassis-from-tetrix
