As per this link lynxmotion.com/images/html/build183.htm on Step 11, it recommends to attach a sensor to the servo, where is the other end attached to? Also how can i check if the sensor is working or not?
It seems this option was never actually implemented with the A-pod code. The principle is that when the grippers contact each other, there is a force exerted on the servo as the plastic moves. The connector would be attached to an analog pin on the microcontroller, or even the analog pins on the SSC-32 (marked as A,B,C,D). You would need to follow the instructions on that page where it indicates how to solder the resistor and arrange the wiring.
Thank you… I have attached the sensor to the servo and have solder the resistor and have arranged the wiring… … I would like to know how can i check if the sensor is working or not? I have to do some programming for that?
What electronics are you using? You will likely have an SSC-32 so you can connect the analog outputs to the pins and test the output using the free SSC-32 software utility:

thank you i will try it with the software utility. I am using mainly the hitech servos and the ssc-32…
lastly what should the sensor do? should i place the sensor directly on the mandible/grippers so that when they contact each other they activate the sensor?
In theory when the grippers contact an object, the rear plastic on the gripper should contact the force sensor, and the harder the servos try to grab the object, the higher the reading on the sensor.
You can use this to ensure objects are not crushed, or simply that an object is within the gripper.
ahtiram, did you find the plastic insert of step 7 in the kit?
