A bond test apparatus includes a test tool, a stage for mounting a bond for testing, and a drive mechanism comprising a voice coil. The voice coil is coupled to either the stage or to the test tool and is configured to provide relative movement between the stage and the test tool such that the bond applies a test force to the test tool. The bond test apparatus can also include a velocity sensor configured to sense an instantaneous relative velocity between the stage and the test tool, and a controller configured to control the drive mechanism in response to a signal from the velocity sensor. The bond test apparatus can also include a retarding mechanism coupled to the stage or the test tool and configured to apply, in response to relative movement between the stage and the test tool, a retarding force opposing the driving force.

Described are systems and methods to utilize an objective function of an aerial vehicle in constructing and/or updating an occupancy map. The described systems and methods can determine whether to include, add, and/or remove an object from an occupancy map based on one or more confidence score(s) that can be determined for the presence (or absence) of an object at a given location. The confidence score for an object at a given location can be determined, for example, based on various sources of information, which can each be provided different weights, parameters, thresholds, etc. based on the objective function of the aerial vehicle.
