Hello i am curently working on a project with the al5d arm, however i coudnt find any informations abaut how much the numbers in the strings that the arm reads (#0 P1600 s750 #1 P1600 s750 #2 P1600 s750… ) eaqual in degrees, or how much 1 degree would be in the string number?
If you are using an ssc-32, you can test your servo using the lynxtrerm application. You can send the arm various us positions and measure the number of degrees the arm moved per commanded position change. I’ve used gizmos like below to test my servos.
ah ty, i will try that out, been trying with geotriangle with the servos build on the arm but the values are to inaccurate, tho as all the servos are diferent i assume that they all have diferent values or are they all the same?
this may also help.
as zoomkat mentioned you could test each plus and measure the angle it outputs…
Taking the total angle of rotation and dividing it by the amount of pulses one can achieve will give you the resolution of the servo. for instance if our servo can rotate 180º with a pwm range of *600uSec *to *2400uSec *(*1500uSec *being centre) Then the PWM range for 180º has a total of 1800uSec pulses with in that range…
180º/1800uSec=.10 we then read this as 10uSec. 10usec is equal to 1º but its debatable as not all servos are the same and some lack in resolution…and i dont wish to get into that. But in the perfect world …yes
