Witryna13 wrz 2014 · 1 Answer. Yes, it is computationally possible (most algorithms are, given enough time and memory). However, I think you should read more into DH, because the above scheme isn't it. And if you have read into it, continue with ECDH because it will perform much better on Java Script. Also note that implementing cryptography in Java … Witryna25 lis 2015 · Step 2: Figure out your axes. The next key step is to draw the axes onto each joint. The DH approach assigns a different axis to each movable joint. If you set up your axes correctly then working with the robot will be easy. Set them up incorrectly and you will suffer countless headaches.
