Building instructions for a LEGO robot that shoots 40 mm ping pong balls. The shooting mechanism is powered by two EV3 Large motors, while the whole mechanism is rotated by a medium motor. The robot can store up to 6 ping pong balls and has a Ultrasonic Sensor to detect targets.
This robot is designed to lift a cup smoothly while keeping it upright. With a motor attached to the side of the Hub, the robot can raise the cup to different angles.
With a few adjustments, you could even replace the LEGO cup and try lifting a real one. Just be careful with liquids - the robot doesn’t enjoy drinks as much as you do!
It sparks. It's sparkling. Well, the goal of this LEGO Mindstorms building instruction is to spark the imagination when the base of the construction is very simple. Just two motors with the brick above them and one of the most classic ways to attach them together - with angled beams.
The construction could use EV3 or NXT wheels, so chose wisely. As a robot chassis base, it is suitable for all kinds of extensions. An interesting thing is the motors are attached to each other with a frame which is getting very popular in the EV3 world.
This instruction adds to the Onwards and cupwards robot.
Modification of the EV3 Competition Robot Full with light sensors attached to the front
This storage box is designed for use in robot missions. Its long shape makes it easy to grab and transport using a wide variety of robot attachments and grabber designs.
Instructions for a simple Crane construction built from LEGO Mindstorms EV3 set. In order to operate properly, you need to add weight at the back of the jib. The most interesting part of the robot is the design of its hand, so examine it closely.
Building instructions for a steering car. The front wheels are steered by a medium motor, while both rear wheels are driven by a single large motor.
Luly is a new STEAM competition robot from LEGO Education SPIKE Prime. We would use in some of the courses. This version of Luly have some light shields to protect the color sensor from ambient light. Check out the courses below and see how Luly is used to complete in a competition.
Minto (from the English word Mintonette) takes its name from the earliest version of volleyball.
This robot can move only forward and backward using one medium motor. It can also shoot a ball using another motor and a clever mechanism. It even has a net, allowing it to catch balls from other robots.
This is an example of a robot for Sumo Robotics competitions. Specifically for RoboteX challenge. As most of the Sumo competitions have specific requirements for the robot size this one follows the 15cm x 15cm requirements.
Sumo competitions could be quite fun and interesting as the goal is to push the other robot outside of the ring.
Xogo means “game” in Galician.
The robot moves using two medium motors. It has a distance sensor in the front to detect the next robot and a force sensor in the back to detect the robot behind it in the relay. Build two or more robots and you can create a whole relay!
Building instructions for a LEGO Mindstorms EV3 Robot Base with 56mm Tires, Version1. The robot base could be used in robotics competitions as FIRST LEGO League, World Robotics Olympiad and others
Malen comes from Malentendu, which means misunderstanding in French.
The robot has a color wheel with 4 colors in the back and a color sensor in the front. When you show a color to the color sensor, it can show it back. You can chain multiple of these robots to make a telephone game!
Building instructions for the Easy Bot built with LEGO Mindstorms EV3 parts. This LEGO robot is suitable for classes with students in robotics and is one of the first robots that we build. It takes about 10-20 minutes to be constructed by first-time participants.
Levi comes from levitama, which means distribute in Estonian.
This robot uses a color sensor to detect the color of a plastic ball. Then, according to the color of the ball, the robot sorts it to the correct side.
In this attachment two knob wheels "(32072 ) Technic Gear 4 Knob" engage at 90 degrees angle. One of the knob wheels is a part of the robot and the other is a part of a pinless active attachment. The purpose of this attachment is to demonstrate How NOT to build attachments.
Build the attachment and experiment. See for yourself how it "jumps" up and down when the knob wheels are rotating and you hold the lever by hand.
Grus, from Latin, means Crane.
The Crane uses one motor to turn the hand and one motor to hold the ball. You need to balance the jib first? What can you add to it?
This is a simple pinless active attachment for the SUV Box Robot.
In this attachment we use "(32498) Technic Gear 36 Tooth Double Bevel". There are four pins added to the wheel and it it this pins that engage with the "(32072 ) Technic Gear 4 Knob". The more important thing is that the knob wheel and the gear wheel are parallel to each other.
While the motor rotates the attachment has 4 points of contact (instead of one or two when two Knob Wheels are in contact) with the robot knob wheel. There are no forces that drive the attachment to jump and lose engagement with the robot.
