I bet a self-balancing two-wheeled robot would be a fun (and relatively safe) project. I mean a Segway-like thing that can just stand in one place without falling over or yeeting itself off the table. You'd need a microcontroller, an IMU, a stepper motor controller, a motor, some LEGO wheels, and maybe a block of wood. I haven't tried this, so my guesses are probably way off.

Sounds like a good project to me (we did this for a couple of labs in an undergraduate [sophomore maybe junior year] control systems class). The "inverted pendulum" problem and its subsequent derivations should be a good model for this. When the object is nearly upright (or at small angles from the vertical axis) a nice linear control loop should suffice but if you leave that region the control solution becomes more difficult (would make a good target for improvement after initially getting it going).
