    Apr 06, 2019 · Camera Array shots are also known as frozen moment or time-slicing or bullet-time (made famous in The Matrix). Because the camera array represents a moving camera path the same path can be defined in a motion control move. This allows all of the other effects that are possible with motion control to be combined with frozen moments.

  • Sensing BLDC motor torque using a current sensor

    What you can absolutely depend on is that the mechanical power delivered by the motor (torque X speed) is equal to the input power (voltage X current) minus losses. You need to be able to accurately estimate the losses. For a system that produces less that 100 watts, losses might be as much as 50 to 100 watts.

    cylinders apply forces to boom, arm and the bucket to actuate the mechanism. Depending on the mechanism position, working pressure and diameter of the hydraulic cylinders, the amount of excavation force changes [1]. Boom, arm and bucket cylinders are used for movement of the linkages out of which arm and boom cylinder are used for digging purpose.

    The definition of torque is force times lever arm. As you state it, force and lever arm are identical, so is the torque. There are differences. Because the moment of inertia differs, the applied torque will cause a different angular velocity (if the force is not in line with the centre of mass).
