Building instructions for this part of the BigDaddy competition robot

You can position the motors on the construction in a number of different ways. We are exploring the advantages and disadvantages of each of them. These are building instructions for the first way to position the LEGO Mindstorms EV3 motors.

This construction demonstrates one way of using а rack with a gear wheel. It allows to turn circular motion in to a liniar one.

This is a frame for the SUV Box Robot. Tis frame is an adapter between the robot and the attachments. You can add-in several attachments on it and mount them on the robot simultaneously with one movement.

The frame has two locks that make the attachments stick to the robot. Also the front Knobs must not be used for very powerful activities due to jumpings, unless the frame with attachments become heavy enough to prevent any jumping of the frame.

Here is an example of Four(4) active LEGO Mindstorms attachments built-in the frame. Two by two they work asynchronously since all of them are connected to the two separate middle motors of the SUV robot via the frame.

The left attachments work synchronously, and the right attachments are also synchronized couple.

These specific attachments are meant to do nothing in particular, but to serve as an example. Their purpose is to demonstrate different ways in which one could add an attachments to the frame. Experiment. Think and invent better frame with real world attachments that could actually do efficient work and accomplish a mission. Take a video then and share it with us. 

Swing game is a SPIKE Prime robot that is a game played by two people. The goal of the game is for both LEGO people to reach the center of the swing, without it tipping over on either side. The LEGO poeple are placed on motors, connected to two technic gear racks, that move along the swing. The motors are moved by two controllers, one using a color sensor and one using a Large motor. If one of the LEGO people moves too far without the other doing the same, the swing will tip and game over! Good luck and have fun!

Calix, from latin, means cup. Calix is made to carry an object while following a black line. Most people, when they think of robotics, they think of how the robots may help them at home, with the chores that no one wants to do. This robot is a simple version of this. You can give it a cup in the kitchen and then it will deliver it to the end of the black line! The robot uses two SPIKE Prime medium motors to move and a color sensor to follow a line. At the front it has Large motor with a gear system that lowers and rises the "cup".

This incredibly compact SPIKE Prime Box Robot is designed for competitions such as the FIRST LEGO League (FLL) and World Robot Olympiad (WRO). Named Whakatae, derived from the Māori word "whakataetae," meaning "competitive," this robot measures 17 LEGO units in length and 15 LEGO units in width. It features two color sensors in front of the wheels for precise alignment, two large motors for movement, and two medium motors for attachments.

The best part? You can build this SPIKE Prime Box Robot using just the Base Set, an additional large motor, and a color sensor!
