I hope you have recieved the shipment of potentiometer
elements for joints 4,5,and 6 plus some extra little parts. There is
still one more shipment to come. This will include the electrical
connectors and a few other assorted goodies. I have also not yet
sent the encoder for joint #3. This is because the ones we bought
have proven unsuitable for the application. I am presently
attempting to have them changed to a different type. This may take a
couple of weeks. If it turns out that this is not possible, I will
send you potentiometers for joints 1 2 and 3 instead. Actually, you
may do well to start with pots, as they will be a bit easier to
interface and employ in your servo system. Later you can switch to
encoders. I'll let you know in a short while about the #3 encoder.
In any event, the encoder just bolts onto the finished arm, lack of
it will not hold up anything for the present.
With this last shipment I believe I have sent you everything
checked off on the accompanying parts list. Some of the parts are
part of assemblies, and others may possibly be a bit different than
specified. I also believe that I have included all the "S" parts I
promised execpt for the cable clamps and mounting hardware which will
be along shortly.
I am also enclosing an invoice for the first set of
shipments. I feel that I have sent you the equivalent of about $5500
out of the $6500 order so far. The remaining $1000 is evenly divided
among unshipped parts and unused consulting time. I also owe you
more written directions and instructions. They are in the process of
being recorded. Of course if you wish to process the whole payment,
I won't complain.
Keep up your patience... I'm working hard.\.
