At first I was amazed because I thought that lego can only be used by building it up using the lego pieces after buying it but a while ago I realized that lego can be used through the computer.

As a designer you should be creative and industrious with a lot of patience. You should not give up easily because you will not gain something without any pain. You should also have interest in the robot rhat you are makin so you can finish it easily. Also, have the knowledge about the physical structure of your robot and know the looks and the purpose of each sensor.
