Allegro MicroSystems is the best way to own the sensing behind scalable humanoid actuators, where the humanoid race will be won. A humanoid has about 43 actuators, each needing current sensing for torque control, where Allegro's magnetic current sensor ICs lead with automotive-grade credentials. Its semiconductor economics scale cheaply: 1M humanoids a year means over 43M sensor ICs on existing fabs. Vishay Precision offers purer force sensing but trades at high multiples with harder scaling. x.comÂ
