How to fix the angles?

[tasosman]

Hi try to use the code to my arm but without good results because for my fault maybe.i have use 4 servos 180 degrees to fix that but is not working properly for mine .here is my build can you help me what i did wrong.in the photo with the build you can see how can the servo move from 0 to 180 .

Hi, without the rest of the code, it is hard to tell what could be wrong. (For example, what does moveToPos do?)

From the information you have provided, I can give you some suggestions:

• The solver takes radians to calculate the solution. b2a and a2b are just helper functions that converts radians to degrees and vice versa. Check if your servos use degrees or radians.
• Make sure that you are getting a solution based on the coordinate and the lengths of the links. Once you get a solution, use the angles (in your case, I see that you named the variables arm0, arm1, etc...) to move the servos.
  • Depending on how you are controlling your servos, maybe you need to transform the radians to degrees from 0 to 180, or from -90 to 90.

I hope this helps you a little!
