  1. Care & Feeding of Machines • Feeding parts • orientation • singulation • Material obtained from: • Boothroyd, Automatic Assembly • Ken Goldberg, UCB Industrial Engr Oper. Rsrch (http://www.ieor.berkeley.edu/~goldberg/index.html) • Robert-Paul Berretty, PhD thesis, Utrecht (http://www.library.uu.nl/digiarchief/dip/diss/1940512/full.pdf)
