Or

(b) (i) Describe a sensing device to generate the contour pictures of a workshop. (8)

(ii)Describe the methods of template matching. (8)

14. (a) Explain the robot work cell arrangements with simple sketch. (16)

Or

(b) (i) State five safety hazards that can be identified within industrial robot installations. (6)

(ii) What are the possible robot applications in manufacturing industries? Classify such robots

from the view points of drives and controls. (10)

15. (a) The robot is to be programmed to pick up a part from point A and move it point B,

followed by a move to a neutral position. Points A and B are to be defined by the programmer

within robots work volume. Then the robot should pick up the part at point b and move it back t

point a, followed by a move to pervious neutral position. The robot can be operated continually

the run mode to repeat the motion pattern over and over. Give the design of the robot.(16) Or

(b) Describe the different search techniques employed by AI program. (16)
