Prepare the Lego blocks and parts you need. Choose the right building blocks and parts according to the design drawings or your own ideas. Design the shape and structure of the mecha. You can draw a sketch first, or simulate it with computer-aided design software. According to the design drawing, assemble the various parts of the mecha step by step. Pay attention to keep the mecha stable and avoid loosening or falling off parts.

Add details and decorations to the mecha. You can use colored building blocks, signs, stickers and other ways to increase the beauty of the mecha. Test the function and stability of the mecha. Check whether each part can move freely to ensure the balance of the center of gravity of the mecha. Adjust and modify as needed. If there is something wrong with the mecha, it can be disassembled and reassembled, or parts can be replaced and optimized.

The inventor of Lego bricks is Ole Kirk Christiansen, who was born in Filzgov village near Billon in 189 1. He has superb carpentry skills. When he was young, he was keen on making all kinds of small toys. Small planes, cars and small animals from his hands are all lifelike. Although he doesn't know how to do business and his toys are often unsalable, it doesn't make him give up his hobby.

Later, his spelling toy "Yoyo" finally became all the rage. 1934, he designed the "Lego" trademark for his building block toys. Ole Kirk Christiansen, the founder, once held a name collection activity for his small toy factory and wooden toys, and his proposal was finally selected, but the trademark name was not legally registered in Denmark until 1954.
