An Important Robotic Part

Glad you are here... thanks to you, the designing of the new robot is complete, and I've started the process of actually making it. Then I realized, we were missing 3 very important mechanical parts necessary to build the robot. I've already given Assistant Cheng of Ludibrium the word, so can you please go there and pick up the pieces for me? Thank you!

I don't think you've met Assistant Cheng yet. I asked Assistant Cheng for the parts, so all you need to do is go there and pick them up for me. Assistant Cheng is located somewhere around the Ludibrium Toy Factory. I'll be waiting for you here.
