Neck mechanism for robot

A neck mechanism for a robot, comprising:

• a first linear actuator;
• a second linear actuator in parallel with the first actuator;
• a rotary stage positioned between an upper platform and a lower platform;
• a support shaft positioned behind and between the first linear actuator and the second linear actuator, wherein the first linear actuator and the second linear actuator are both connected between the upper platform and the rotary stage via joints, and wherein the support shaft is connected between the upper platform and the rotary stage via a joint;
• a rotary motor;
• and
• a control system that receives command instructions, wherein the control system controls the rotary motor to rotate the rotary stage to yaw the upper platform according to the command instructions, controls the first linear actuator and the second linear actuator to pitch the upper platform according to the command instructions, and controls the first linear actuator and the second linear actuator to roll the upper platform according to the command instructions.

A method for controlling a neck mechanism for a robot, comprising:

• providing a first linear actuator and a second linear actuator in parallel with the first actuator;
• providing a rotary stage positioned between an upper platform and a lower platform;
• providing a support shaft positioned behind and between the first linear actuator and the second linear actuator, wherein the first linear actuator and the second linear actuator are both connected between the upper platform and the rotary stage via joints, and wherein the support shaft is connected between the upper platform and the rotary stage via a joint;
• providing a rotary motor;
• rotating, using the rotary motor, the rotary stage to yaw the upper platform according to command instructions;
• pitching the upper platform using the first linear actuator and the second linear actuator according to the command instructions;
• and
• rolling the upper platform using first linear actuator and the second linear actuator according to the command instructions.
