Dear Mr. Talmo:
Enclosed are the force sensors I talked to you about.
The gold colored aluminum part is a prototype wrist force
sensor for a robot arm. The accompanying drawing shows the locations
of the 16 gages. You previously used the model 9003 gages with 500
ohms resistance. These appear satisfactory, so you may use them
again if they appear to be the most suitable type. The enclosed piece of
p.c. board may be used as a lead attachment and strain relief point.
You may glue it in place once the gages are installed, as we do not
have to remove it. There are two holes for each gage lead. We will
attach our instrumentation wires to one of them, the other is for your
The second part of this order is a pair of force sensing
fingers for our robot arm. The sketch shows the location of the 4
strain gages on each finger. I have enclosed the sketch and
instructions as I recieved them from the Stanford student who is
doing this experiment. Should his specifications be too rigid, let
me know and I can talk to him about relaxing his requirements.
I'd like a quote on the price of each unit in advance of
starting the work, so please call me when you have looked over the
parts. For comparison, I'd also appreciate a price with the U- gages
instead of the straight type.
As a result of my last discussion with you, I am looking at
making future force sensors in Nispan C or Kovar. In the meantime I
hope you will be able to handle these aluminum units. As a point of
reference, the job you did for us at Stanford University about 2
years ago was excellent, even though the sensor was the same 7075-T6
