Building Instructions

Building instructions for a LEGO Mindstorms EV3 robot that we call Space Explorer. The motors are attached in a very interesting way to the brick. Both the brick and the motors are vertical and there are not many robots like this. With its ultrasonic sensor, this robot allows you to follow, find or avoid objects. Just like an explorer. And since it is a robot why not put it in space and call it "Space Explorer".

There is one part that is not from the EV3 sets, but you can actually skip it. You don't need it. Try to find which one.

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. 

This is version 2 of the LEGO Mindstorms Grabber. It makes use of 4 gears to make both levers active.  

Building instructions for the LEGO Mindstorms EV3 Catapult. The robot has a motor, a clutch to control it for manual shooting and a touch sensor for automatic loading. The bottom base is removed which means the Catapult could not be turned around. Nevertheless, the baseless robot is small enough to be built in class.

This is another LEGO Mindstorms grabber, but this time it has 4 fingers! They are moved simultaneously by a medium motor. The grabber was taken from Cron - LEGO Mindstorms EV3 Crane.

This is a module that is made to look like a polar bear head, but really it could be used for many animals. It uses a medium motor to bite and an ultrasonic sensor for eyes. We have labeled it a polar bear head, because it is used in Polar Bear - LEGO Mindstorms EV3 Robot that looks like a polar bear.

Building instructions for the EasyBot LEGO Mindstorms robot using in many of our courses and tutorials. This EasyBot has two motors and two front wheels. The third wheel is...well, check it out, see how the third wheel is built. 

This LEGO Mindstorms EV3 robot chassis has the brick positioned vertically. Interesting idea that could be very useful.

Building instructions for a LEGO Mindstorms EV3 Robot that we call CastorBot, because it uses the castor ball. 

Classical third wheel for LEGO Mindstorms robots. This construction comes from the NXT world and the wheel is available in the NXT set. 

Let's go fast. Large wheels on the back. A lot of torque, small wheels on the front, good aerodynamics. Here we go.

These are building instructions for a LEGO Mindstorms EV3 Drag Car. 

This is a simple robot, variation of the Earl bot using treads. You can use the attachment to kick balls sideways. The robot is useful in STEM classes where students have to construct robots quickly.

Instructions for building remote control. It uses the rotation sensor to determine the steering and touch sensor for handling the movement. Find building instructions for a suitable chassis here. 

Together the controller and the car look like this:

This is the third version of the LEGO Mindstorms Grabber. This time we use a LEGO EV3 Medium motor and worm gear to make the two levers move smoothly and symmetrically.

Laboratory 2.0 is a second and lighter version of the Laboratory. The new version of the robot replaces its motor with a gyroscope and uses a lightweight flip. Programming this robot requires a well-developed abstract thinking. The main purpose of the robot is to measure the volume of the bubble placed in it only by the values ​​measured by the sensors.

The construction has a valve with which you can let the air out of the balloon at different speeds.

How exactly the balloon is placed in the robot is explained in this lesson.
