possibility for step by step tutorial?

[Yuuki44]

Hello everyone, I acquired a robotic arm from robotshop a while ago: lynxmotion-al5d-4-degrees-of-freedom-robotic-arm i already know how to code and control it with arduino but i would like to try something more advanced.

during my search for something evolutive i found this framework and ROS but ROS seems to be very complicated for me. My point is that I am a beginner in python and have tried the test programs and tried to understand the documentation but I can't seem to put it all into practice ...

Can anyone create a step-by-step tutorial on a "fairly simple" example model like the TX90? Like how to enter coordinates of a point and find the IK of this point, how to connect 2 points together, how to plan the trajectory, how to set up the simulation, how to link the simulate robot and the real robot ... etc.

maybe I ask a lot but it could help a lot of people in my case who doesn't know how to make a work because they do not know how to do it based only on the documentation and give up

thank you!

You're in luck that there's actually an AL5D model in Klampt-examples.

The Inverse Kinematics page on the manual is the closest thing we have so far to a beginner tutorial on IK. You'll just need to know the link index of the end effector, which in the AL5D case is 4. Once you've solved for a point-to-point motion, you can then follow the steps in the Paths and Trajectories page to execute the path.

But I agree that it would be helpful for beginners to have a complete start-to-finish example. I will put this on the TODO list.
