Building Instructions

Zatter is the big brother of Zat and Zatty. Zatter is here to take the load. It has a large container on its back, suitable for placing different toys inside and playing with them. Built from LEGO SPIKE Core set 45678 + LEGO SPIKE Expansion Set 45680 it was designed by my wife and just slightly improved by me and my colleagues. We spend a good hour or two with the kids placing different plush toys and playing with it.

Play time for a week: About an hour

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.

Tempus means time in Latin.

Time flies when you are having fun! Luckily, we have this robot to keep us on top of our schedule. Tempus is a robot that 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 the robot simple to build and effective in showing how a clock works.

This is an attachment for extracting the raw materials. This attachment is made for Kamak box robot.

The program for this attachment is FLL 2018: Attachment To Accomplish The Into Orbit Extraction (05) Robot Game With Kamak - Box Robot - Demo Program

Building instructions for the barrier mission model. The model is used in the Parking Control mission of FLLCasts Off-season Challenge 2019.

Building instructions for the transportation stands mission models. The models are used in the Precise driving mission of FLLCasts Off-season Challenge 2019.

This robot is robot based on Roberto Chassis. It is equiped with a pushing rack. You can add something to the rack so it can do some other jobs.

The program for this robot is at programs/ajk7i1-roberto-with-rack-for-pushing-to-the-left-and-right-side-vex-iq-robot.

In this 3D scheme, you can see how the motor driver is connected to the Raspberry Pi and to the motor. Follow the steps in the instructions one by one and you will have successfully connected the motor to the Raspberry PI

In this spreadsheet, we have the values for the Integral part and the Gyro sensor for moving straight with the robot.

A simple robot for classes, with Vex IQ Touch Sensor.

User this flywheels construction for experiments in physics. Start rotating the wheel and they would accumulate energy. You can try to calculate this energy and to measure how fast it would be consumed.

The construction is built with LEGO Mindstorms EV3

Building instructions for this part of the BigDaddy competition robot

The rotation frame requiers an NXT large double gear wheel that is not available at the EV3 set. You can use the instructions below to construct a similar mechanism from Mindstorms EV3 set

A FIRST LEGO League 2023-2024 attachment for the MiniBox Robot.

This attachment uses rubber parts to compensate for the lack of precision in positioning the robot near the mission model. That was needed since at the time that this attachment was used, the robot had moved a long distance since its last aligning at a wall or other mission models.

This attachment is designed to detach, once it completes its purpose. This is done, so that the team loses less time switching attachments in the base, lowering the chance of human error during the competition.
