Tutorial would be nice #7
Comments
Thanks. You are completely right. I hope to have some time in future to do it, but I don't expect it to be soon.
Meanwhile you can take a look at the test file: https://github.com/cdsousa/SymPyBotics/blob/master/sympybotics/tests/test_results.py |
I implemented the basic DH formalism for my own, just to learn and understand it: https://github.com/balzer82/Robot-Kinematic Would be nice if you could at least show a way to achieve this with SymPyBotics! Thanks |
Well, its just a matter of mapping your >>> import sympy
>>> import sympybotics
>>> rbtdef = sympybotics.RobotDef('Example Robot', # robot name
... # list of tuples with Denavit-Hartenberg parameters
... # (alpha, a, d, theta)
... [('-pi/2', 0, 0, 'q+pi/2'),
... ( 'pi/2', 0, 0, 'q')],
... (..., ..., ..., ...),
... ...
... (..., ..., ..., ...), # last link
... dh_convention='standard' # either 'standard' or 'modified'
... ) |
@cdsousa I used the PUMA560 model in the test file, and I found that the result is not same with the Matlab robotics toolbox. |
This is worrying. @lyhbuaa can you add the code for both so I can reproduce it. thanks. |
Hi! Great work. Unfortunately I do not understand all details. A tutorial would be nice, where you (graphically) describe, what are the parameters to set up a robot and work with your functions.
E.g. you wrote 'q+pi/2' and so on: What is q?
