A magnetic screwdriver device includes a pad without magnetism, a driving shaft, and a driven shaft. The two shafts, magnetically attracted to each other, are disposed on opposite sides of the pad. The driving shaft is used to transmit a torque to rotate the driven shaft. When the torque exceeds a predetermined value to overcome a friction force between the driven shaft and the pad, the driven shaft would be stopped.

Magnetic screwdriver device

A magnetic screwdriver device includes one pad without magnetism, one driving shaft, and one driven shaft. The two shafts, which have magnetic attraction between each other, are disposed on opposite sides of the pad respectively and attract to each other. The driving shaft is used to transmit torque to actuate the driven shaft rotation. When the torque out of predetermined value overcomes the friction force between the driven shaft and the pad, the driven shaft will be stop.

A mobile vehicle, a ground treating equipment and an orientation adjusting method thereof are provided. The ground treating equipment includes a frame, a ground treating unit, a connecting rod set, a connecting rod driving unit, a rotation driving unit, two pressure sensors and a controller. The ground treating unit is mounted at the frame. Two ends of the connecting rod set are connected to the frame and the mobile vehicle. The connecting rod driving unit is mounted at the connecting rod set for adjusting the orientation of the connecting rod set. The rotation driving unit is mounted between the frame and the connecting rod set for driving the frame to rotate relative to the connecting rod set. The pressure sensors are mounted at the frame for sensing two pressure values between the frame and ground, or the pressure sensors are mounted at the rotation driving unit for sensing two pressure values while the frame is driven to rotate clockwise and counter-clockwise. The controller is configured to control the connecting rod driving unit and the rotation driving unit for changing the two pressure values.

Mobile vehicle, ground treating equipment and orientation adjusting method thereof

An on-line measuring system, a datum calibrating method, a deviation measuring method and a computer-readable medium are provided. The datum calibrating method includes following steps. A work piece is scanned by a scanning unit to obtain a global point cloud data. A local CAD data of the work piece is obtained according to a predetermined range. A local CAD geometric feature of the local CAD data is obtained. A local point cloud data of the global point cloud data is obtained according to a local range corresponding to the predetermined range. A local scanning geometric feature of the local point cloud data is obtained. The local scanning geometric feature and the local CAD geometric feature are compared to obtain at least one spatial freedom limit. A system basis is obtained according to six spatial freedom limits, if the number of the at least one spatial freedom limit reaches six.
