It is really expensive to hire a sports trainer to learn postures ('forms'). Posture is critical for playing any sports like Tennis, Golf, Baseball, etc.
How about building a robot that teaches you the form. Based on the device below, it should be relatively easy to build a robot like that. On an application, put in sports you want, have the robot measure dimension of your body, put some sensors on the racket, and Go!
It can have you do the optimal posture for any instrument at any number of times until your body remembers.
Or have your robot correct your posture in real time while you play sports. Anyways, future will be fun.
