Hello, at 4:05 I think Prof. Lynch meant the mass matrix value depends on the "configuration" not "acceleration". The force itself, however, is the quantity that depends on acceleration for a particular configuration I guess.

my comment is blocked?? 0:22 equation is wrong.. plz modify it.. \dot{V_b} should be \dot{v_b} - w \times \dot{q}

Pro tip: the cross product is anticommutative, so -omega × q can be rewritten as q × omega. Which is much easier to remember and will make programming much simpler by eliminating an easy to introduce error

i couldn't understand how Js3 is unaffected by joint 3's rotation
@kaishang6406 Ай бұрын
check 5:12, notice that S3 is to the right of the adjoint matrix. I think that is how it works.
@kaishang6406 Ай бұрын
I rewatched this a bit more and i think you need to reconsider what jacobian, twist, and screws represent. they aren't like vectors in 3d space but rather an extended version of axis of rotation. With that, you should see how the js3 (axis of rotation like thing that describes joint 3) is not affected by the rotation of joint 3.

In the torque equation at 5:05 it should be c(theta)*theta dot instead of c(theta, theta dot) right?

There are another videos for that. It´s hard to understand so I totally agreed with that ... this type of knowledge is hard to find so I think is a truly opportunity ... Work hard bro :)
@ky8920 7 ай бұрын
if you watch the previous 24 videos from the playlist, it is not hard to understand it. you only need to learn the basic of screw motion/theory that unified the translational and rotational motion

Thanks for the video. I didn't understand how when specifying C, we have moved B away from the circumference of the point A. Isn't B supposed to be at the circumference of A?
