      Hi DJ,

      I'm by no means an expert on this, but I thought I'd take a stab. For fragile stuff, I'd recommend a piezoelectric or capactive sensor. A quick google search turned up this: http://www.trossenrobotics.com/c/robot-force-sensor-fsr.aspx which may or may not be what you're looking for, but could at least be a good starting point. 

      Hope this helps!

       I am a newbie. It might be very basic and typical Question :)
      I have a 6 DOF Serial robotic arm manipulator (ED7220C). At the moment it is only equipped with motor encoders. What I want to do is to let the gripper hold various kinds of objects (fragile objects like egg without breaking it and rigid objects like metallic). One way is to add Force sensors to the Gripper and then implement closed-loop feedback control system. What kind of sensors I need? Any clue (part no)? Would be happy to read your experiences? Secondly, is there more better and easy way of achieving my goal?
      Thanks for your help.
