Abstract
Disclosed are systems and methods for computing an object's weight or the quantity of items within the object based on activations of different robot actuators used in retrieving the object from a storage location. Specifically, the robot may activate one or more actuators during retrieval of an object, may obtain a measurement in response to activating a particular actuator, and may derive a weight of the object based on the measurement by converting the measurement from a first range of values that are associated with activations of the particular actuator to a second range of values that are disassociated with activations of the particular actuator. The robot may then modify its operation in response to the weight that is derived for the object matching or being mismatched to an expected or last tracked weight.
