Building Instructions

There is a lot of physics and math involved when learning with LEGO Mindstorms EV3 robots. It is generally "difficult" to include them directly during classes because students are coming for "something funnier" and at the same time, they could be of different ages. But Inertia is a pretty common topic that is quite easy to introduce to students, especially with a robot. 
The robot moves and stops. What will happen with the cargo when the robot stops? Naturally, the cargo will continue moving and this is dangerous. For how long, what would be the energy? All these are things that could be discussed with this robot.
The robot is not completely finished because you have to finish it and decide on the wheels to be used. 

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

Take a motorcycle and start removing parts. You get a chopper. Like this one. It is built with LEGO Mindstorms EV3. It has one large and one medium motor. It could kind of turn, but moving forward with it is very funny. There is a "more sports like version" available at Ninja - Sports Motorcycle built with LEGO Mindstorms EV3

Currently, the motorcycle has no sensors. It's more of an exercise in construction, but if you attach sensors and think of a way to attach them send us a picture. 

Join the course A robot a "day" keeps the questions awake where we will further discuss the motorcycles, how to build them and what tasks to accomplish with them. 

You can find some demo programs here.

Building instructions for a LEGO EV3 steering car. We use two large motors, so that the rear wheels will be driven independently by a separate motor. For your convinience, you can use the EV3-G MyBlock for moving the Boomer.

Building instructions for a LEGO Mindstorms Robot that cleans the landing site when landing on a different planet. Built from an EV3 set it is a perfect simple tank robot with continuous tracks for lifting and moving things. Basically cleaning.   

Building instructions for a Robot Grabber used in the World Robotics Olympiad competition runs. The grabber is build with LEGO Mindstorms EV3. The base of the robot is available at /materials/69-wro-robot-2014-elementary 

Attachment used to transfer the motion from the motor from a vertical axle to a horizontal axle. Uses two gear wheels. Could be built with LEGO Mindstorms EV3 and LEGO Mindstorms NXT kits.   

This is a simple LEGO EV3 Mindstorms Robot that can collect items within itself.

This robot is part of the category of robots called animals. After following the building instructions you would have a frog that could jump. Of course, the jump depends on the surface and the friction between the robot and the ground... quite complex physics involved. But if you program it to move forward it will try to jump and it is your job to try to make it jump higher. 

You could try to extend some of the legs, for example.

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

This robot attachment shows you how to limit the rotation of a lever. It uses two gear wheels to transfer the motion on 90 degrees. 

It could be built with LEGO Mindstorms EV3 and NXT versions. Most of the time during competitions like FIRST LEGO League and World Robotics Olympiad you need a lever for just a limited motion

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.

The goal of these building instructions is to build a LEGO Mindstorms EV3 robot without wheels. You should then decide on your own how exactly to add the wheel. Which wheels would you use at the front? How are you going to build the third wheel? Here are some recommendations on building the third wheel - 1,2,3,4 

A LEGO Mindstorms EV3 Chassis with wheels at the front. Built with the EV3 set you can use this robot chassis as a base for extending with attachments. 

Building instructions for a LEGO Truck. The robot is presented as an Ammo Truck but it can be used for transporting various other objects, too. The construction has a rear drive with each of the rear wheels driven by a Large Lego Motor. The front wheels steer using a Medium Lego Motor. The Brick is placed at the front of the construction which gives the opportunity to easily attach different sensors, based on the task. 

Building instructions for a steering car. The front wheels steer through a Medium LEGO EV3 motor while the rear wheels are both driven by a single Large LEGO EV3 motor.

Building instructions for the Formula 1 Racing Car, built with LEGO Mindstorms EV3. It can turn with the help of a small motor and is driven by two large ones.

An example program for using this robot could be found at: https://www.fllcasts.com/programs/692hkz-comet-program

Building instructions for a robot for the World Robotics Olympiad Sputnik competition. This is the light version without the lift at the top.

No need for all attachments to be powered by motors and to include gears. It's sometimes possible to use a simple robot attachment to collect objects. Such attachments we call passive and this one is an example for the Box Robot Chassis.

Build with LEGO Mindstorms EV3 

Building instructions for a LEGO EV3 Robo-tank. The construction is incredibly simple, with an upright Brick, which makes it perfectly suitable for lessons with students.
