3.2 Electronic Hardware
The electronic hardware measures changes in resistance; the software described in Section 3.4—ATI DAQ
Software, converts the changes to force and torque components.
Figure 3.2 and Figure 3.3 depict an example of the electronic hardware used in a DAQ system. The gures
also illustrate how the transducer’s voltage signal, created as a response to applied forces and torques are
processed and routed to the DAQ card for conversion to usable force and torque data.
