Skill of type selecting of coder of position of An Chuan robot

01 μ M, if the computation in the type on the basis is in 4 as a result at the back of fraction, it is for instance 0.

3125 μ M/pulse, so the numerical value that you input can be only 0.

31 or 0.

32, that is to say of the robot along with use rate the meeting is quick slow perhaps the effective rate at conveyer belt, this kind of circumstance is very deadly for accurate to certain requirement equipment. Article delibrate a kind of more direct computation robot the method of positional resolution. For example: The spot uses servo drive system, the lead of transmission guide screw is 25mm, the decelerate of decelerate machine is compared is 10:1, the spot follows those who move coder to use is 2000rpp. We use the computational method of robot manual, we are actual the result of numerate is 0.

3125 μ M/pulse, so we can be used only 0.

31 or 0.

The numerical value of 32, can bring about a robot to follow the with conveyer belt effective rate in using a process so abhorrent. But the problem goes it where we are checked very hard is clear that where we are checked very hard. If we calculate first,come out Ink> servo electric machinery turns the mobile distance of lap conveyer belt: 25 ÷ 10=2.

5mm, can know conveyer belt is mobile 2.

5mm needs feedback 2000 pulse, so the positional resolution of numerate is 2.

5 ÷ (2000 × 4) =0.

3125 μ M, calculate type in 4 because the robot is receiving the processing that does 4 times frequency into the metropolis when coder,be, the pulse that so the robot receives counts 4 times be actual feedback pulse. From above we can see two kinds of algorithm, the value of the positional resolution of our numerate is consistent, but the 2nd kind of algorithm can let what we find a problem settle way more. That is to say, we can alter according to actual condition the decelerate of machine of the lead of guide screw, decelerate is compared or follow the model that uses coder, with respect to the size of the value that can change positional resolution, assure to reach the designated position accurately of buy resolution most subsection. Still be the example above, if we along with move coder instead 500rpp, so the positional resolution of our numerate is: 2.

5 ÷ (500 × 4) =1.

25 μ M, can assure a robot along with move speed to agree absolutely with conveyer belt speed. Of course, if we ask the resolution of coder as far as possible tall, so we can alter the lead of guide screw perhaps alters the decelerate of decelerate machine is compared, can achieve similar result. Such we can be designed in early days when, of first consideration robot along with the consistency that move, avoid to create the passive situation that later period transforms afresh again.
