Abstract:
A collaborative robot employs low ratio drives for three or more axes of movement, such as three primary axes. An arm assembly may be mounted to a support for movement along a vertical linear axis, and the arm assembly may include first and second arm links that are each rotatable about vertical axes, e.g., such that the arm links move in a horizontal plane. Low ratio drives may be used for movement along the vertical linear axis and the rotary axes for the first and second arm links. Feedforward and feedback control may be employed to control the movement of the arm assembly and arm links, and feedback torque components may be limited to 25% or less of the maximum drive torque.

Claim (Index 1):
A robot comprising:\n a base, a vertical support extending from the base along a vertical linear axis, an arm assembly supported by the vertical support and moveable relative to the vertical support along the vertical linear axis, an arm assembly drive arranged to move the arm assembly relative to the vertical support, the arm assembly drive including a motor and clutchless drive train arranged to move the arm assembly, the arm assembly drive motor and drive train, having a drive ratio of less than 25:1 and arranged to move the arm assembly without slip of the drive train, the arm assembly further comprising:\n a first arm link coupled to the vertical support and arranged to rotate relative to the base about a first rotary axis that is oriented in a vertical direction, \n a first link drive including a motor and clutchless drive train arranged to rotate the first arm link relative to the base about the first rotary axis, the first link drive motor and drive train, having a drive ratio of less than 25:1 and arranged to move the first arm link without slip of the drive train, \n a second arm link coupled to the first arm link and arranged to rotate relative to the first arm link about a second rotary axis that is oriented in the vertical direction, the second rotary axis being spaced from the first rotary axis, \n a second link drive including a motor and clutchless drive train arranged to rotate the second arm link relative to the first arm link about the second rotary axis, the second link drive motor and drive train, having a drive ratio of less than 25:1 and arranged to move the second arm link without slip of the drive train, and \n a third link coupled to the second arm link and arranged to rotate relative to the second arm link about a third rotary axis, and \n a controller constructed and arranged to provide control signals to the arm assembly drive and to the first and second link drives to move the arm assembly, the first arm link and the second arm link.
