This is both correct and incorrect.

Boston Dynamics use control-systems style robotic control. This is different to ML-style control where the system learns to perform tasks.

But that's different to "pre-programmed sequence". They don't program the individual servo movements for each movement - instead they give it the motions to perform and the control-systems balance the robot automatically.

(This is what the OP implied by the word "algorithms" anyway right?)
