Abstract
A machine includes a chassis, a linkage having a first end pivotally attached to the chassis at a first pivot point, and a bucket pivotally attached to a second end of the linkage at a second pivot point and rotatable about the second pivot point from a first position where gravity resists rotation of the bucket to a second position where gravity assists rotation of the bucket. A tilt actuator rotates the bucket about the pivot point and one or more sensors provide physical data of the bucket. A processor of the machine receives the physical data, determines from the physical data an equilibrium position of the bucket, determines a location of the center of gravity of the bucket with payload from the physical data and the equilibrium position, and estimates the weight of the payload based on the physical data and the location of the center of gravity.
