In this video we discuss how do we transfer power from the motors that are "inside the robot box" to the gear wheels that are "outside the robot box".
It's the second version of the Robot Base 4, but with rotated inside motor.
Based on your feedback we have decided to show you the live process of building a complex LEGO Mindstorms Competition robot without having the whole robot ready yet. We are continuing from part 1 where we finished part of the 'front' of the robot and we arrived at a construction that we didn`t like and would fix in this video lesson.
One of the very common tasks on different FIRST Technical Challenge competitions is to collect objects. In this case, these are colourful specifically shaped plastic object or in simple terms - balls.
The next challenge of the course is to build a container where you could store the balls (objects) that you are collecting. The first thing is to see how it works as an end result. You can use the same principle during FIRST Technical Challenge competitions. You can also fire the balls, just by rotating the axle in reverse.
Building instructions for the Pinless Rubber Band Attachment:
We've built a box robot chassis that could easily be extended with attachments for FIRST Technical Challenge competition.
If you ever felt that FIRST Technical Challenge is difficult and you don't know where to start from, building this Tetrix robot is the first thing that you could do. You would have 4 motors, plenty of space for attachments and good access to the phone.
The robot is built from a Tetrix Set without additional parts. It's a winning robot in just 109 steps
Should the robot be with a Front Wheel Drive or a Rear Wheel Drive to make it more precise? The answer is - front wheel will probably give you better results, but the wheel drive is not the most important thing. In this video tutorial on the LEGO Mindstorms Robots, we will do a few experiments to discuss the influence of the wheel drive on the precision of the movement.
Building instructions for probably the simplest LEGO Mindstorms EV3 Motorcycle that you could think of. Can you think of a simpler? Build it and send it to us.
The motorcycle has one large and one medium motor. Turns are hard, but we will think of solutions for turns. There are also other motorcycles, more complex ones that you could build
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.
The CubeHunter uses the ultrasonic sensor to detect a ball or cube. Next, the robot catches it and reads the colour of the object using the EV3 colour sensor. The building instructions are suitable for classes with students and if you are working alone at home.
These are building instructions for an attachment accomplishing the FIRST LEGO League 2017-2018 Slingshot mission. The based of the robot is LEGO Box Robot Three With Large Wheels and Thee light sensors and one Gyro
Mintonet (engl. Mintonette) comes from the name of the first iteration of volleyball.
The robot can move only forward and backward, without turning, with the help of a large EV3 motor. Another large motor is used to shoot. The robot uses an EV3 ultrasonic sensor to detect its partner and throw a ball at it.
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.
Iknathir from armenian means aircraft carrier.
The robot is made to resemble an aircraft carrier. It shoots paper airplanes using two fast spinning wheels. The wheels are connected to a gear up mechanisms which are connected to two Large motors. The motors themselves are connected to a medium motor, which allows them to move towards and outwards the plane so when they reach it, they are spinning at full speed. The plane is placed on a runway which leads it to launch successfully. On the side of the robot, there is a lever with a gyro sensor, which is used to trigger the launching mechanism.
Let's play some basketball
Tricky might be the smallest Mindstorms 51515 Robot Inventor robot, but it's definitely one of the greatest. If you build Tricky with this particular Basketball attachment and grab the Mindstorms/Duplo ball, which is included in the set, you'll unlock a whole new level in playing basketball at home. Yes, yes, we know that you'll also need a basketball hoop, so you'll find a link for it below.
You can find the LEGO set, with which this was built, by following this link.
You can find other attachments for Tricky, by following the links below:
You can find constructions created to play with Tricky, by following the links below:
You need a model to lift with the robot. This is a nice looking model where you could experiment with moving the robot and lifting the load
