Wudi Zhou Dummy Arm Team 4

Project Overview An 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.

Potential Patent Infringements US System and Method for Motion Tracking Using a Calibration Unit US (6DoF) Inertial Motion Capture System with Initial Orientation Determination Capability

Patent: US System and Method for Motion Tracking Using a Calibration Unit Claim Motion 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.

Analysis of Patent Liability We might be Literally infringing their patent Methods to get motion data( sensors’ position ) System’s overall connection Basically the same function performed the same way Solution Obtain License

US (6DoF) Inertial Motion Capture System with Initial Orientation Determination Capability Claim A motion capture system measuring change in spatial orientation An 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 magnetometer Sensors wirelessly transmits said motion data

Analysis of Patent Liability We might have Doctrine of Equivalents issue Basically the same algorithm( both use compass to get a fixed external coordinate ) Wirelessly transmits sensors’ data Almost same sensors, besides gyro Solution Obtain License

Thank you!
