robotics

It took me a while to learn too use the tinker cad but I managed to make my rover and I am happy with my mars lander rover.

I sketched my mars lander.and the first step Is ask for help for your build.step 2 Is plan and sketch and make.step 3 is to create and design

So they know about the know a little bit about the center of earth but mars they
made a robot and then they will put it on the red mars planet and then make it measure the temperature and
earthquakes in the planet and also scan and other stuff

Does not work but i learnt a bit  I know how to put the code in but it failed but not work but I,m using the speak function and the roll function.
