Thank you very much! Greetings from Germany.

Thank you for the lecture. Can you briefly recap questions from the audience to the microphone?

this is awesome

49:35 Can someone teach me why a fully-actuated system can be equivalent to a double integrator (q''=u) ? This means the input u (torque) can directly equal to the second differential of output q (position)? Thanks!

As I understood, If you have a fully-actuated system, that means you can get u from q'' = f1(q,q',t) + f2(q,q',t)u in form u = f2^-1(q,q',t)(q'' - f1(q,q',t)). And now, taking the last equation, you can "change" q'' to any control you want (f.e u*) and passing u to the first equation get q'' = u*, meaning you can fully control accelerations. You can find more info in lecture notes (underactuated.csail.mit.edu/intro.html#section3)

Sir how can I access the python codes you used in the lecture can you provide the link. can't find it

@@rtedrake ok, thanks! You are awesome!

Thanks a lot. It's a very good course but there is room for improvement for the camera.
