Multiple-sensor robot system for obtaining two-dimensional image and three-dimensional position information

A multiple-sensor robot system comprising:

• a robot;
• a multiple sensor comprising:
• first sensing means for obtaining a two-dimensional image within a relatively large area, and
• second sensing means for measuring a three-dimensional position within a relative small area by projecting light on the relative small area;
• means for outputting an operation command for said first sensor means;
• means for outputting an operation command for said second sensor means;
• means for processing an image signal obtained by said first sensor means;
• means for processing a measurement output signal of said second sensor means;
• robot control means for controlling said robot;
• wherein said processing of said image signal from said first sensor means includes processing for determining a position of an object to be measured in said relatively large area;
• said robot control means includes means for making said robot perform an approach movement to said object based on said determined position of said object;
• and
• said processing of said measurement output signal from said second sensor means includes processing of said measuring output signal outputted after said second sensor means is moved to an approach position by said approach movement.
