lego mechanical workshop

Every Saturday I go to Bryne creek secondary school for robotic Lego building classes and I partnered with a boy named Arlow.

At the first Lego class I made a car that includes batteries to make it go.

Once all cars were made,we had a race and I won! its because the gear in m was really big.

To learn more about it watch the explaining video.
