Abstract: A computing system and method for estimating friction and/or center of mass (CoM) are presented. The system may perform the method by selecting at least one of: (i) a first joint from among a plurality of joints, or (ii) a first arm segment from among a plurality of arm segments. The computing system further outputs a set of one or more movement commands for causing robot arm movement that includes relative movement between the first arm segment and a second arm segment via the first joint, and receiving a set of actuation data and a set of movement data associated with the first joint or the first arm segment. The computing system further determines, based on the set of actuation data and the set of movement data, at least one of: (i) a friction parameter estimate or (ii) a CoM estimate.

Abstract: An electronic circuit comprises a charge storing component, a set of one or more switching components coupled to the charge storing component, and an additional switching component coupled to each of the one or more switching components in the set. The additional switching component is configured to operate in a first state or a second state based on a received current or voltage. The first state prevents current to flow from the charge storing component to each of the one or more switching components in the set and the second state allows current to flow from the charge storing component to each of the one or more switching components in the set.
