Step 7.
Attach a nylon wire tie to the wires. Attach an ohm meter to the FSR wires. Gently slide the rubber foot
over the sensor and tip of the foot. Push it on till the meter reads some resistance, then carefully and
slowly work the rubber end cap in the opposite direction just till the meter reads open. If you are unable
to get the meter to read open (infinite resistance) then you may need to adjust the wire tie, or the bend
on the sensor in Step 5. After proper set up the sensor should read open until it makes contact with the
ground.
On a moving robot, the rubber end cap holds the sensor in place even with significant lateral loading.
Also the sensor will return to an open even after being under load for a long time. This simple robust
design will easily handle the weight of our AH3-R robot.
Step 8.
There are many ways to use the FSR, but the simplest is to just use a 10k pull-up resistor.
Using setup "A" shown in Figure 8, we were able to get the following response, illustrated by the red
line in the Sensor Output Chart.
Using setup "B" shown in Figure 8, we were able to get the following response, illustrated by the blue
line in the Sensor Output Chart.
