Dear Professor Luh:

\J
	I have  just shipped  another set  of parts.   This  shipment
includes the  outer joint potentiometer elements, the tachometers for
joints 4 ,5 and 6,  and a few extra parts.   I have had some  trouble
with the encoder  for joint #3 and am presently  negotiating with the
manufacturer  for a  different type.   Thus,  this item will  be sent
later.  I am still waiting for some of the  parts associated with the
wiring of  the arm and will send  you them when they arrive.   In the
meantime, you should go ahead and finish the mechanical assembly as I
anticipate no large changes.  The #3 encoder mounts externally, and thus does
not require disassembly of the arm to install.

	As I  feel I have  sent you the  major part of  the component
set,  I am  sending Purdue an  invoice for  $5,500 out of  the $6,500
price.   The other  $1,000 will  be billed  when I  deliver the  one
remaining encoder and the wiring materials and connectors.  Please be
as prompt as you can with payment as I am operating on a very limited
budget and am keyed into prompt payment of my invoices. 

	I have also enclosed some more assembly details, which should
clarify the picture a bit  furthur.  My present schedule calls for me
to go East around  May 15, so I  will not be able  to pass by  Purdue
before about May 25.   In any event, I will let you  know my definite
plans in advance.  In the meantime, don't count on me at any definite
time, as I could even be a week or two late again. \.
