drawer / Software
Control that predicts the output needed (e.g., to overcome gravity or reach a velocity) and is combined with PID for accuracy.

where you actually meet Feedforward
Feedforward is why a good shooter recovers to speed between shots instead of dipping. PID reacts to error; feedforward predicts the voltage the mechanism needs — kS to break friction, kV for velocity, kG to hold an arm against gravity. Once you characterise those constants, PID only has to clean up the remainder, and tuning becomes far less painful.
Free and structured, and none of them need an account to read.

the jargon travels in packs
Software
A feedback control loop (Proportional-Integral-Derivative) that drives a mechanism to a target by reacting to error.

A sensor that measures rotation/position of a shaft, essential for closed-loop control and odometry.
read the entryMechanical
The ratio between input and output rotation in a gearbox, trading speed for torque (or vice-versa).
read the entrySoftware
A trajectory-optimization tool that generates time-optimal autonomous paths, often paired with WPILib.
