Hello
I currently work on a project where a robot picks cast iron parts out of a bin. The position and orientation of the parts are more or less random. The parts are located using a vision system. Sometimes the parts are entangled. Because of this, the robot might pick 2 or more parts at a time in some cases. The customer will not accept this, so he suggests that we mount a load sensor on the tool unit. By measuring the weight of the gripped parts, we should be able to determine whether we have gripped more than one part. I don't know how heavy the parts are, but my guess is that they weigh around 0.5 kg each.
So my question is: Do any of you have experience using a load/weight sensor mounted on the tool? Does it sound realistic to solve the problem using a weight sensor?
The sensor needs to be relatively compact, and must be able to withstand forces that are much greater than the forces it is measuring.
Thanks in advance!
