(c)
Briefly explain the two stage control of manipulator using interpolation of end effectors position method. or Discuss applications and working principle of the following sensors. i) Range sensors ii) ii) Acoustic sensors iii) Tactile sensors.
(d)
Write a VAL robot program to perform pick and place operation on the conveyer system. It consist of two conveyors running para llel with with centre ce ntre distance of 600 mm at same level.
