Building Instructions -

• Robot Base Chassis

Building instructions for the robot build with LEGO Mindstorms EV3. It is called "Frankenstein" because the two motors are in two different directions.

This almost box robot is build from the LEGO Mindstorms Robot Inventor set. The idea behind this robot is to be able to build it from Robot Inventor and to use it during FIRST LEGO League competitions

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 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.

Simple VEX IQ competition base with a lot of space for attachments and gravity center in the backside of the robot.

A very simple base of the robot that could be used for adding attachments.

Building instructions for a LEGO Mindstorms EV3 robot that could be completed in about 3 minutes. Could you do it? Try it. 

We use this robot when we need something very fast for a demonstration or a small competition. Just attach the motors and you are ready. It is fast.

It's a VEX IQ robot base with all VEX IQ Sensors. The robot has 1 x Gyro, 1 x Ultrasonic, 1x Color Sensor, 2 x Toch Sensors, 1 x Touch Led Sensor.

This is the robot that we use to demonstrate a solution for the World Robot Olympiad 2021 Junior competition. This is a Post season solution. We never release any solutions during the season as this will have a negative impact on the competition.

We started with this robot and it has a few good ideas. It can collect two cars at the same time. We later decided to go for a more powerful robot. Check out WRO 2021 Junior: Slaimi - a post season WRO competition solution robot

It's the second version of the Robot Base 4, but with rotated inside motor.

It's the third version of the VEX IQ Easy Bot with rotated Robot Brain and castor wheel.

Introducing Kufar! In Bulgarian, Kufar means "suitcase," and just like a suitcase, this robot is easy to "pack" with different attachments for each task.

Unlike traditional box robots, Kufar is an "out-of-box" design, enabling fast, easy attachment swaps. This flexibility allows teams to build a new chassis with customized attachments for each run, making transitions quick but requiring more parts and careful handling due to its gear transmission, which can sometimes cause gear slippage or play.

To improve precision, Kufar’s gear transmission is optimized for lower speeds. Kufar also includes a color sensor to detect specific colored bricks on attachments and a force sensor to start corresponding programs. With two motors for movement and one for attachments, Kufar is compact, efficient, and easy to handle, especially with its sturdy top handle.

We thoroughly enjoyed exploring this innovative concept and hope you find it equally fun and inspiring!

Mitko is an example for a small robot from LEGO Education SPIKE Prime. It has no sensors, but it has a big container, like a big mouth. So it can collect things, although it can not see them. Like a small animal that is blind, but hungry. Mitko could be used as a base for a robot that needs to collect. In was one of the versions of a robot that we used for a World Robot Olympiad competition.

Zat is fun. Zat is great. It is a simple construction for a car with 4 large wheels. And who does not like cars with large wheels. Built from LEGO SPIKE Core set 45678 + LEGO SPIKE Expansion Set 45680 we had a lot of fun with it on Sunday. It was an idea of my wife and the kids took a lot of time putting things on in and moving it around. Just put things on it and play with it.
