Results are provided in table 3. For the insertion of the radiused-square component the offsets were the same as before and for the insertion of the circular component a higher offset was used and no rotation was given. The time for each insertion was computed with the learning ability on Lon and also with learning inhibited Loff that is using only the initial ACQ-PKB. The assembly operation was always successful and in general faster in most cases when the learning was enabled compared with inhibited learning.
