simple machines

 

with the Lego wedo  I made two machines the raising  car and  a mars rover.at the strat I did not know how to see the build then I realised it only shows the basic part  then I had to see what they look like and copy it.  when I did the raising car at the start it did not move then I removed a block of the program and then it started. when I made it I went   forwards then  stop when it sees a wall. The simple machine was the axel at the back

the other one I did was the mars rover it was pretty easy after I did the raising car. the bit at the top is the motion sensor and that detects the wall

.what I made was the elevator, in the elevator the was a pully witch is a simple machine

By the end of the 2 weeks I learnt that it was really easy to make simple machines
