Building Instructions

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

An awesome ski-jet robot, steering with a medium motor and powered by a single large motor. It also has a pair of inclined treads, making it especially well-suited for the harsh winter terrain.

*There is a mistake in this robot you will have to find. How would you make it work?

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 rotation sensor in the medium motor to detect how much the players had turned its wheel.

Value was inspired by the spy vehicle robot. This little robot was built to measure the volume of the room he's in.

Building instructions for a LEGO Mindstorms EV3 Motorcycle, but this time with helper wheels. The helper wheels solve the problem of making turns with the robot. If the robot loses balance it will fall. The goal of the helper wheels is to make it easier for the robot to turn. Small modification, but really make a difference. 

Chronos means time in Greek.

What's the time? Time to build a cool robot! This robot is made to look like a clock. The two hands are each connected to a motor and are positioned between the two motors. This makes it simple to build, while also being effective in showing how a clock works.

An example program moving the seconds and minutes hands of the clock can be found here.

An example program designed to teach children to read the clock can be found here.

Building instructions for a LEGO Mindstorms EV3 robot base. The attachment of the motors is quite interesting. We follow the angles of LEGO technic to attach them. This construction has some difficulties turning to the left and to the right. But if you have to take on an obstacle that high this is one of the options. 

You can use all kinds of wheels on this robot - EV3, NXT or others. It doesn't actually matter.

Building instructions for a LEGO Mindstorms EV3 active attachment for changing gears orientations. This is the second attachment from the series.

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 color sensor to detect the colors on its wheel.

Dwell is a car built with a LEGO MINDSTORMS EV3 set. It uses the medium motor for powering the back wheel and one more medium motor for rotating the front wheels and thus turning. Of course, there is a differential at the back.  

Winter might be far away or it might just be coming - depending of course on where you are in the world. But you can always spend a few hours having fun with a LEGO Mindstorms Snowmobile. A really challenging construction that requires good preparation, concentration and a lot of efforts to complete. Same is going to the mountain in the winter. But the reward at the end is worth it. 

This a the Dinore3x, the predecessor of the mighty Triceratops. This is one of the classic EV3 robots provided by LEGO. 

Not all LEGO Mindstorms EV3 Robot should be aligned horizontally or vertically. It is quite possible to have the brick and the motors attached in such a way that the robot is at a certain angle. 

This is a very useful small construction that could be used as a base and extended with hands and heads or other interesting ....robot body parts.

This LEGO Mindstorms Attachment has three gears, one frame and two axles. The goal of the attachment is to use the gears to change the direction in which the motion is transferred.  

Whitiki comes from Maori and means Belt.

The robot uses a medium motor to run the belt and a color sensor to identify the color of the ball coming in. There are 56 chain pieces in the robot.

Building instructions for a LEGO Mindstorms EV3 Ambulance Robot Attachment for the FIRST LEGO League 2013 Nature's Fury robotics competition.    The attachment grabs the ambulance car and slightly lifts it. The rubber bands help with triggering the attachment at the right time

This attachment have a guider mechanism that align the robot to the attachment. The attachment woks with SUV Box Robot.

Building instructions for the Pinless Rubber Band Attachment:

One LEGO gear is powering two LEGO Gears and at the end, from one motor we rotate two axles in opposite directions. Follow the building instructions.
