Servo-robotic asymmetric rotational mixer and system

1. An asymmetrical rotation mixer for mixing materials, the asymmetrical rotation mixer comprising:

(a) a rotational mount for receiving a container housing one or more materials for rotational mixing, the rotational mount having a primary vertical rotational axis and a secondary rotational axis wherein the secondary rotational axis is arranged at an angle a from horizontal and offset from the primary vertical axis;

(b) a servo motor for providing rotational drive to the rotational mount, the servo motor including a servo motor control system for maintaining angular position control of an output shaft engaged to drive rotation of the rotational mount and maintaining positional control of the rotational mount through the action of the servo motor; and

(c) a mixer control system including a user interface for receiving input of a mixing profile, wherein the mixer control system provides indication of the mixing profile to the servo motor for execution.

2. The asymmetrical rotation mixer of claim 1 , further comprising a sensor for sensing the angular position of the output shaft for feedback control by the servo motor control system.

3. The asymmetrical rotation mixer of claim 2 , wherein the server controller system includes a servo controller configured to apply proportional-integral-derivative (PID) control to the angular position of the output shaft based on the information from the sensor.

4. The asymmetrical rotation mixer of claim 1 , wherein the output shaft is directly coupled to the rotational mount to drive the rotational mount for rotation about the primary axis with a 1:1 ratio.

5. The asymmetrical rotation mixer of claim 1 , wherein the servo motor control system executes the mixing profile, and wherein the servo controller system applies a proportional- integral-derivative control to the angular position of the output shaft to accommodate inertial mismatch between the one or more materials and the servo motor.

6. The asymmetrical rotation mixer of claim 1 , further comprising one or more sensors to sense the state of the one or more materials, the one or more sensors comprising at least one of a torque sensor, a temperature sensor, and an optical sensor.

7. The asymmetrical rotation mixer of claim 6 , wherein the one or more sensors includes two different sensors, and wherein in response to signals sensed by the two different sensors, the state of one or more materials is determined to be completely mixed.

8. The asymmetrical rotation mixer of claim 6 , wherein in response to a sensed state of the one or more materials indicating the materials are completely mixed, the servo motor system stops rotation of the servo motor.

9. The asymmetrical rotation mixer of claim 1 , wherein the received input of the mixing profile is changed via the user interface.
