Jeez Al - did you miss the "This effect is more pronounced on high frequency AC than it is on DC or low frequency AC" caveat or the "flexibility is key" line in the original post? And "Very little" is not accurate. The robot is NOT a static load. The load is variable with components (of the load) related to the rotation of the motors etc. People confuse this all the time, DC means Direct Current, not Direct Voltage. And direct current does not always imply constant current. Nor is the robot's ground reference an infinite sink. Just because the source is a battery does not mean the load can't vary, perhaps with some periodicity. This effect in the robot is important enough to be aware of.
