The input current still should reflect the output current switching waveforms. We used a current sense circuit many years ago called StangSense. The current waveform was then filtered and processed to provide a usable output.

We have not tried the circuitry on a Jaguar equipped robot. As there is considerable rise time issues at low throttle (small PWM pulses), an implementation would need some massaging to be accurate. It is my understanding that the current sense in the Jaguar is primarily looking at peaks not average currents. It is a simple resistor in one of the power supply leads. The current flow produces a voltage drop across the resistor which is then converted and used by the onboard processor.
