Mechatronics Engineering Principles
Where the electrical, mechanical and software tracks meet
A robot is not an electrical system with motors attached; it is one system whose parts constrain each other. This track is about choosing actuators, measuring what they did, closing the loop, and describing where the machine actually is.
Sensing, Actuating and Controlling
Actuators, encoders, PID and kinematics
- Choosing an ActuatorFreeBrushed, stepper, servo or brushless, what each is genuinely good at, and how to size one properly.14 min
- Encoders & Position FeedbackFreeKnowing where the machine actually is, rather than where you told it to go.13 min
- PID ControlFreeThe three terms, what each actually does, and a tuning method that is not guesswork.15 min
- Kinematics & Degrees of FreedomFreeDescribing where a machine can go, converting joint angles into positions, and the harder problem of going the other way.14 min
