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.<p>It was only around £70 for the servos + metal framework.  I drive it with a Pi and a PCA9685 based I2C board.<p>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.<p>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.<p>Tangentially related, I just bought 'The Ultimate Guide To DIY Animatronics' yesterday, which I'm looking forward to reading when it arrives.<p>And have been watching a few videos on animatronics such as:<p>* <a href="https://www.youtube.com/watch?v=y0R8-F4TmPI">https://www.youtube.com/watch?v=y0R8-F4TmPI</a> - 'Show and Tell: Animatronic Raven Kit!'<p>* <a href="https://www.youtube.com/watch?v=uNIfx0Xddzc">https://www.youtube.com/watch?v=uNIfx0Xddzc</a> - 'How Realistic Animatronics Are Made For Movies & TV | Movies Insider'<p>Curious if anyone has any recommendations for videos/books in this area?
