Ask HN: Courses/textbook recommendations for studying robotics?
I bought a 6DOF robot arm a while ago, which uses servos driven by PWM, which I found quite fun.It was only around £70 for the servos + metal framework.  I drive it with a Pi and a PCA9685 based I2C board.I was driving with a 5V supply, but it looks like the servos can run at 6V, which I need to try, as the bottom servo in the arm doesn't seem to have quite enough power.I'd like to sometime try to 'teach' it to draw with a pen (however badly), 'Inverse kinematics' feels rather scary though, so wonder if anyone might have any very basic tutorials on this.Tangentially related, I just bought 'The Ultimate Guide To DIY Animatronics' yesterday, which I'm looking forward to reading when it arrives.And have been watching a few videos on animatronics such as:* https://www.youtube.com/watch?v=y0R8-F4TmPI - 'Show and Tell: Animatronic Raven Kit!'* https://www.youtube.com/watch?v=uNIfx0Xddzc - 'How Realistic Animatronics Are Made For Movies & TV | Movies Insider'Curious if anyone has any recommendations for videos/books in this area?
