Abstract
A controlling apparatus is provided. According to an example, the controlling apparatus comprises: an operating body configured to bear acting forces; a mechanical sensing apparatus arranged on a surface of the operating body and configured to sense the acting forces and convert the acting forces into electric signals; and a controlling module configured to determine a resultant force of the acting forces according to the electric signals and control a controlled object to move along a direction of the resultant force of the acting forces.
Claims16
A controlling apparatus to control a controlled object to move, comprising:
- one operating body configured to bear acting forces, wherein the operating body is cylindrical and rotatable, the controlled object is a scanning bed, and the operating body is disposed beside the scanning bed;
- a mechanical sensing apparatus configured on a surface of the operating body to sense the acting forces and convert the acting forces into electric signals;
- and
- a controlling module configured to determine a resultant force of the acting forces according to the electric signals and control the controlled object to move along a direction of the resultant force;
- wherein the controlling module comprises:
- a signal amplifier configured to amplify the electric signals from the mechanical sensing apparatus and output amplified electric signals;
- an analog-to-digital converter configured to convert the amplified electric signals from the signal amplifier into digital signals;
- and
- a controller configured to determine the resultant force of the acting forces according to the digital signals from the analog-to-digital converter and control the controlled object to move along the direction of the resultant force;
- wherein the mechanical sensing apparatus comprises a plurality of stress sensors configured to convert the acting forces at respective positions of the plurality of stress sensors into the electric signals, wherein the plurality of stress sensors are uniformly distributed on the surface of the operating body and contacted with each other;
- and
- wherein the controlling module receives the electric signals output by the plurality of stress sensors and determines the resultant force of the acting forces according to the electric signals and position information of one or more of the plurality of stress sensors on the surface of the operating body, wherein the one or more of the plurality of stress sensors bear the acting forces.
