In our lab we mostly use ATI 6DOF force sensors, but they are so difficult that I just want to kill myself every time I have to use them. The reasons I don't like them are:

  1. For the version I have (Mini45), I have to use a NI DAQ to read data from and NI DAQmx drivers are only x86 and mostly windows, not compatible with mac, Arduino or Rasperry pi which I use to control experimental setups.
  2. I could have used one of those NetBoxes, but I have to pay a couple of thousands to buy one, probably a couple of thousands to calibrate the sensor, and wait a couple of month to get it calibrated and etc.
  3. They are so difficult to use. They have this GUI (only windows) which you have to install (which BTW reminds me of the kind of software we used to use in 90s). They have also some LabView examples. These are way too complicated to get around!
  4. Even when you get them to work the signal is horribly noisy and you have to do all kind of magic filtering to get something useful.
  5. they are very sensitive. For example if they are in contact with a cold metal or there is air blowing at them (which in my experiments including pneumatics happening a lot), they just give wrong measurements.
  6. They are so delicate that if you bend the cable too much or screw them to your structure too hard they are broken and you have to pay a couple of thousands to send them back and fix!
  7. the whole sensor+driver+DAQ is like a whole table full of cables and boxes!
  8. customer service is bad. They are just like chatbots giving you pre-prepared answers!
  9. no forum or user community (to my knowledge)

I just don't know why everyone keep using them. I'm really tired of all that wasting my time and resources. I was wondering if you could give me some suggestions. What I need

  1. one dimensional force sensor
  2. 5V analogue output which I can measure with for example Arduino. Or a USB serial port which I can read with PuTTy for example.
  3. up to 1200N
  4. resolution is not that important. If I use an Arduino to read then 1200/1023 is the maximum resolution I can read anyway.
  5. It must be affordable. not more than 100€ lets say
  6. available here in Europe. with good local customer service
  7. with good examples and tutorials and good user community

I did google first, but there seems to be way too much options that I'm confused which one to choose. Thought maybe you can share experience and give me some insights.

    $\begingroup$ Welcome to Robotics Foad, but I'm afraid that shopping questions really aren't a good fit for a stack exchange site. We prefer practical, answerable questions based on actual problems that you face. Take a look at How to Ask and tour for more information on how stack exchange works, and the Robotics question checklist for details of how to write a good question. $\endgroup$ – Mark Booth Sep 4 '17 at 15:16
  • $\begingroup$ @MarkBooth Thanks for letting me know. Should I remove the question? Or is there anyway to improve it? $\endgroup$ – Foad Sep 5 '17 at 12:37

    $\begingroup$ Generally speaking it is better to ask how to solve a problem, rather than ask what you can buy to solve a problem. An answer which makes a recommendation might only be valid for a short time, an answer which explains the principals behind the solution and helps you select a suitable product will continue to be useful far longer. It is up to you whether you delete this and post a new question, but since at least one person thought your question was useful, and there are no answers yet, if you edit this question to fit community guidelines (linked previously) then we can re-open it for you. $\endgroup$ – Mark Booth Sep 5 '17 at 14:18
  • $\begingroup$ Thanks, I will come back to this post later and will edit it based on your FB. $\endgroup$ – Foad Sep 5 '17 at 18:33
