This is a problem for robotic planning in the block world. It is for an artificial intelligence course.

1. (5 points) Below is the setbasic robotactions: pickup(x): P&D:ontable(x),clear(x), handempty A holding(x) putdown(x): P&D: holding(x) A: ontable(x), clear(x), handempty stack(x, y): P&D: holding(x), clear(y) A: handempty, on(x.y), clear(x) unstack(x, y):- P&D: handempty, clear(x), on(xy)A: holding(x), clear(y) a) Define how the two STRIPS rules, pickup(x)andstack(x,y) could be combined into a macro-rule 'put(x,y)'. Whatare the preconditions, delete list, and add list ofthe new rule? b) 1.
