Abstract: A method for positioning an intelligent terminal apparatus comprises: acquiring data points scanned by a position detection device in the intelligent terminal apparatus at the current position of the intelligent terminal apparatus; converting valid data points into segment features to obtain a first set of segment features; and converting point features in an established map of the intelligent terminal apparatus into segment features to obtain a second set of segment features; selecting, from the first and second set of segment features, segments having the same position relationship respectively to form a first and a second candidate subset of the first and the second set of segment features respectively; and determining a transformation matrix that matches the first candidate subset to the second candidate subset, and identifying the current position and the orientation angle of the intelligent terminal apparatus in the established map based on the transformation matrix.

Abstract: An omni wheel, a motion device and a control method thereof are disclosed. The omni wheel includes a center wheel and a plurality of peripheral wheels distributed in a circle with respect to an axis of the center wheel; and a peripheral wheel brake component disposed on the centre wheel and configured to control a resistance of the peripheral wheels during a rotation of the peripheral wheels. The omni wheel solves the problem of low braking performance of the motion device by increasing the resistance of the peripheral wheels during rotation, and avoids any random rotation of the peripheral wheels.
