RESEARCH ON SPATIAL LOCATION OF A SPHERICAL 3-RRR PARALLEL MECHANISM

The quaternion is used to represent the finite rotation of rigid body, and the finite rotation equation of rigid body is obtained.Based on the spherical 3-RRR parallel robot, an angular displacement sensor bracket is added to detect the attitude angle of the moving platform, and the positioning deviation is transformed into a quaternion form.Thus,

In India, the Tibetan Lighting Wolf Canis lupus chanko is distributed in the Trans-Himalaya region.We report the sighting of Tibetan Wolf from the Bedini-Ali area that falls in the Greater Himalayan range and is located in the transition zone of Nanda Devi Biosphere Reserve in Uttarakhand, India.We hypothesise that the Tibetan wolf inhabiting the T
