Building Instructions -

• Robot Base Chassis

Here is an idea. What if a robot does not need attachments. What if there is one special attachment on the front that could do most of the work? Probably an attachment that allows you to move a lever in any direction.

This here is a Box Robot with X - Y axys plane. This robot doesn't need active attachments because it has X - Y table that do the job. Imagine that there is a plane on the front of the robot. With the rack mechanism you can move to any coordinates on this plane. 

We have a lot of ideas how to make it even better. We will try to release them in the next few versions.

Building instructions for a Light LEGO Mindstorms EV3 Competition Robot that could be used in LEGO Robotics competitions. Compared with previous versions of this robot, this one has a Gyro Sensor. 

This is a LEGO Mindstorms EV3 competition robot used in FIRST LEGO League competitions and used by a team in Brazilian regionals. It followsa Box Robot principle. The robot has passed through the following competitions in Brazil:

Local competition in scholl
Regional: Northeast 
National: Rio de Janeiro
International: Uruguay 

It is not entirely "clean" as it has parts of it not optimezed as in the other box robots, but it is a nice example and a great work from the FLL team.  

This is a LEGO Mindstorms EV3 competition robot used in FIRST LEGO League Season 2018-2019 Into Orbit following a Box Robot principle. The robot has passed through the following competitions in Brazil:

Local competition in scho
Regional: Northeast 
National: Rio de Janeiro
International: Uruguay 

The robot is an modular construction that you could easily build upon. It is not entirely "clean" as it has parts of it not optimezed as in the other box robots, but it is a nice example and a great work from the FLL team.  

This is a vehicle that is used to help you to learn programming, to experiment with addons, attachments and constructions. It has a frame. Which is nice. A frame is always nice. 

It has two wheels at the back, but this is needed only if you have them.

This is a simple chassis that uses two motors to control the robot and two omni wheels at the back for greater maneuverability. It also have low center of the mass which makes it more stable for higher attachments.

The program for this robot is at programs/uxgw6b-roberto-bot-chassis-controls-with-modkit

This one is also fast. It has assistant wheels, but only to keep the balance. It is built with LEGO Mindstorms EV3 sets with the use of one additional Medium Motor. 

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

The demo programs for this motorcycle are here.

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

Later on you can expland this construction with a grabber as demosntrated here. 

Building instructions for a simple chain tread machine. The robot is actually a simplified version of the Freedom Folk Race tank. All of the ultrasonic sensors are stripped away and the robot can be used for multiple different tasks. The construction is appealing to students and simple enough to be included in a class.

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

It's fast. It's on two wheels. It's a motorcycle. And this one is built from LEGO Mindstorms EV3 sets with the use of one additional Medium Motor. If you have two medium motors, great. If you don't have you can build the  Handlebar - Chopper Motorcycle built with LEGO Mindstorms EV3, because it uses one large and one medium motor that are available in any EV3 set.

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.

We had a couple of minutes before starting another robot and we just came up with this robot. If you would like to build a Box Robot, but don't have enough parts this is a good construction that you could learn from. It has a frame. It has three motors. You can add attachments at the top. 

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.

This is the chassis for the popular FTC Push Bot. The robot is built with the Tetrix set and uses two motors. When preparing for a FIRST Technical Challenge competition (FTC) it is very useful to have a chassis from which you could start working. It might not, and will surely not be the final robot, but a good base is always useful. 

With this chassis, we've also made a short course of how to control it. Take a look at FIRST Technical Challenge. Basic GamePads, control and attachments for the Tetrix set.

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 robot extends the Tetrix Box Robot chassis for FTC competitions with an additional arm. The arm could be used for lifting and placing objects and could be quite useful. 

There is a special rubber band at the end of the arm, because there are not enough parts in the Tetrix set and we had to use a rubber band. But the principle of the arm is interesting, useful and you should be familiar with it - the arm keeps the motors always in the right orientation.   

LEGO Mindstorms EV3 Robot designed for a Folk Race competition. This robot has three Ultrasonic Sensors. Follow the building instructions and at the end, you would have a very basic robot with tank treads that you could directly use.
