5119 results about "Body frame" patented technology

A large body frame is a skeletal structure that is bigger, wider, or denser than average. A person with a larger frame often stands taller and is broader than his or her peers. It’s easy to confuse big frames with fatness, but the two are usually really different.

Pedometer navigator system

A pedometer navigator system is carried by a pedestrian, the pedometer system providing present position data as the pedestrian walks across terrain to be surveyed. The body frame is coupled to the pedestrian. An Euler Angle Measuring Subsystem (EAMS) coupled to a body frame measures and outputs the Euler angles of a fixed coordinate system with respect to an earth fixed navigational coordinate system. A left and right sensor is mounted on the pedestrian's respective left and right foot. An SBPMS (short baseline position measuring subsystem) is coupled to the body frame and has a position measuring coordinate system. The SBPMS measures and provides a respective left vector {right arrow over (rho)}leftp and a right vector {right arrow over (rho)}rightp characterizing the position of the left and right sensors with respect to the position measuring coordinate system origin. A computer and algorithm means responds to the Euler angles of the body frame coordinate system with respect to the earth fixed navigational coordinate system and the left vector and the right vector by determining an interval during which the left or right foot is stationary and for providing a transition vector referenced to the earth fixed navigational coordinate system characterizing the movement of the SBPMS origin during the interval the respective foot is stationary. A navigation algorithm adds each transition vector to the previous present position of the navigation reference system to obtain a next present position of the position measuring subsystem.

Four-leg robot mechanism based on bionic design

The invention relates to a four-leg robot mechanism based on a bionic design. The four-leg robot mechanism consists of a body frame and four legs. The body frame consists of a front plate and a rear plate, two sides of the body frame are provided with flexible handles, and the robot mechanism is convenient to convey; each leg comprises a hip, a huckle, a knee and a crural part; the hip realizes two freedom degrees by adopting a differential bevel gear; the hip and the huckle are connected by an expansion sleeve to realize fast and convenient assembly and disassembly; the bevel gear drive motion is adopted by the knee; the crural part comprises a large cylinder, a small cylinder, a conical spring and a force sensor; and the large cylinder and the small cylinder are connected through the conical spring, so that the external impact force generated in the walking process of the robot can be buffered, the force sensor on a sole can acquire ground acting force, and the external environment can be conveniently sensed in real time and the robot can be subjected to balanced control conveniently. Through the bionic design idea, a spinal cord and a flexible foot mechanism of the robot are stimulated and designed, the flexibility of the robot movement is improved, the impact of the ground to the robot is reduced, and the robot mechanism has a compact structure and is convenient to install.
