Dummy Arm Team 4

Wudi ZhouDummy ArmTeam 4

Project OverviewAn remote controlled robot arm with 6 degree of freedom. It is controlled by a control sleeve. Control sleeve is responsible for measuring the motion of the human arm. Robot arm will mimic the same motion.The additional degree of freedom is from the rotation of wrist. 2Potential Patent InfringementsUS7725279 System and Method for Motion Tracking Using a Calibration UnitUS7219033 (6DoF) Inertial Motion Capture System with Initial Orientation Determination Capability

2010, 20073Patent: US7725279 System and Method for Motion Tracking Using a Calibration Unit

ClaimMotion tracking system for tracking a movement of an object in a three dimensional space.The said object being composed of object portions having individual dimensions and being sequentially interconnected by joints.The system comprises orientation measurement units .

20104Analysis of Patent LiabilityWe might be Literally infringing their patentMethods to get motion data( sensors position )Systems overall connectionBasically the same function performed the same way

SolutionObtain LicenseUS7219033 (6DoF) Inertial Motion Capture System with Initial Orientation Determination Capability

ClaimA motion capture system measuring change in spatial orientationAn electronic data acquisition system includes inertial sensors that can be embedded onto moving device Sensors consists of tri-axial accelerometer, a tri-axial gyro, and a tri-axial magnetometerSensors wirelessly transmits said motion data

Analysis of Patent LiabilityWe might have Doctrine of Equivalents issueBasically the same algorithm( both use compass to get a fixed external coordinate )Wirelessly transmits sensors dataAlmost same sensors, besides gyro
