Foundational sim-to-real control testbeds: pendulum, cart-pole & SO-101

Classical control testbeds that validate the simulation-to-hardware pipeline step by step. ST's STEVAL-EDUKIT01 is the reference pendulum; two DIY stepper rigs (rotary pendulum and cart-pole) follow, then an SO-101 leader/follower arm pair that later becomes the humanoid's arms. A Bambu Lab P1S prints the structures.
