A measurement system according to the present embodiment includes a work tool, a sensor unit, an acquisition unit, a change unit, and a calculation unit. The work tool has a tread board with a variable width. The sensor unit is provided in the work tool. The acquisition unit acquires, from the sensor unit, time-series data on gravity center sway of a worker, in a state where the worker is standing on the tread board. The change unit reduces the width of the tread board in response to a trigger. The calculation unit calculates, from the time-series data, an evaluation value for the gravity center sway of the worker, for each width of the tread board.

A system for determining a discrete number of flexible, non-rigid workpiece items loaded onto a robotic carrier. The system includes a robotic carrier capable of traveling to multiple workstations, at least one of which is a weigh station. A loading mechanism is functional to load one or more workpieces onto the robotic carrier which weighed by the weigh station. By comparing the weight of the loaded items with a predetermined weight range of a single workpiece, the number of discrete workpieces loaded onto the robotic carrier can be determined. In addition, a method can be provided for determine position error of a mobile robot based on a detected center of gravity of the mobile robot.

The present disclosure provides an onboard object measurement system for a vehicle, such as a lift truck. The vehicle may have one or more sensors incorporated thereon, such as within one or more load handling fixtures. Control circuitry associated with the vehicle and/or the sensors is configured to receive data from the first sensor corresponding to changes in force in the first axis, receive data from the second sensor corresponding to changes in force in the second axis, correlate the changes in force along the first and second axes, and to determine one or more of a direction of motion, a thrust, or a position of a center of gravity associated with the load based on the correlation.

Vehicle center of gravity (CoG) height and mass estimation techniques utilize a light detection and ranging (LIDAR) sensor configured to emit light pulses and capture reflected light pulses that collectively form LIDAR point cloud data and a controller configured to estimate the CoG height and the mass of the vehicle during a steady-state operating condition of the vehicle by processing the LIDAR point cloud data to identify a ground plane, identifying a height difference between (i) a nominal distance from the LIDAR sensor to the ground plane and (ii) an estimated distance from the LIDAR sensor to the ground plane using the processed LIDAR point cloud data, estimating the vehicle CoG height as a difference between (i) a nominal vehicle CoG height and the height difference, and estimating the vehicle mass based on one of (i) vehicle CoG metrics and (ii) dampening metrics of a suspension of the vehicle.

A vehicle includes a sprung mass including a cabin coupled to a chassis, tractive assemblies each including at least one tractive element, springs coupling the tractive elements to the sprung mass, each spring imparting an upward force on the sprung mass, load sensors each configured to provide a signal indicative of the force imparted by one of the springs, and a controller operatively coupled to the load sensors. The controller is configured to determine a weight of the sprung mass using the signals from the load sensors and monitor at least one operational condition of the vehicle. The controller is configured to determine whether or not to disable determination of the weight based on the at least one operational condition.

A load calculator includes a coefficient storage, a replacement deriver, and an internal-load deriver. The storage stores a first coefficient, an internal load acting on a target point in a target member when a unit load acts on a concentrated load point in the target member along one of three orthogonal axes, and as a second coefficient, an internal load acting on the target point when a unit moment acts on the concentrated load point around one of the axes. The replacement deriver derives a replacement load and moment by replacing an external load acting on the target member with six force components acting on the concentrated load point. The internal load deriver derives an internal load acting on any target point with the first coefficient, the replacement load, the second coefficient, and the replacement moment when the external load acts on the target member.

The invention relates to a method for reducing an imbalance of a projectile shell. The projectile shell has a body (1) which has a recess (4). By this recess (4), the body is provided with an inner wall (2) and an outer wall (3). In addition, a mouth hole (6) is provided, which is connected to the recess (4). A central axis (5) is now calculated from the outer geometrical shape of the projectile shell and a measurement is then performed to ascertain an imbalance of the projectile shell. On the basis of the measured imbalance, modified axis (8) is then calculated in relation to the central axis (5), and the body (1) is rotated about the modified axis (8) on the basis of the calculated modified axis (8). As the body (1) is rotated in this way, the projectile shell is machined to eliminate the imbalance as far as possible.

The present disclosure provides an inspection device for use in a mounting system including a mounting device for disposing a component on a board, including a control section configured to extract a mass area included in a captured image resulting from imaging a processing target object where a viscous fluid is formed at a predetermined part, obtain a center of gravity of the mass area so extracted, and determine whether the center of gravity is included in a normal range of the predetermined part as a reference of the captured image to thereby determine whether a bridge has occurred where the viscous fluid is formed over adjacent predetermined parts.
