Get up to forest2 and enter the teleporter that takes you to the centeral dome and there should be another teleporter, this takes you to a small area were you normally find "moon atomisers", and walk straight, this should get you the head. Go in to the quest status and open Lionels head, this should give hints on where the other parts are.Use the teleporter that got you into this room back out and continue uptothe large teleporter that takes you to fight the dragon and you see a room that is normally locked[ only unlocked if you killed a hilldebear] go back to that room, then a hilldebear should jump down kill it and you will get lionel's left arm. His right arm is back in forest1 in a large room ina a creek.1 of his legs is in the first room you enter in cave2[no parts in cave 1]but over other side.Go to quest status and open his head again this should tell where the other leg is. Once you find it use a "tellipipe" or "ryuker" ang go near the hunters guild then you should see the guy in black that said "that he found something and wanted to sell it"talk to him and he will give you the robot's body. Hope this helps, if not then your going to have to do it yourself.
