I used to like playing with electric constructors when I was a kid and something like this is perfect for me to get back into the hobby.
Then this: "We previously learnt how to derive a Jacobian which relates the velocity of a point, defined relative to one coordinate frame, to the velocity relative to a different coordinate frame. Now we extend that to the 3D case." https://robotacademy.net.au/masterclass/velocity-kinematics-...
But yeah, robotics is really tough - I tried a course on Coursera once and found it too challenging despite my Physics major background.
I want to learn it though as it'd be a cool hobby to share when I have kids etc.
What's the issue?
