A simple and straightforward implementation of the DH-parameters in MATLAB
There are two different conventions on the implementation of the DH-parameters. This one uses the standard DH-parameters which can as well be found in this book: https://www.cs.duke.edu/brd/Teaching/Bio/asmb/current/Papers/chap3-forward-kinematics.pdf. The results have been validated with Peter Corke's RVC toolbox (https://github.com/petercorke/robotics-toolbox-matlab).
cgr prefix means the code is code-generation ready.
ncgr means the code is NOT code-generation ready.
Features:
- Forward kinematics
- Homogenous transformation of each link of the robot
- Numerical Jacobian
- Simple visualization, it can also be animated
- Inverse kinematics with the pseudo-inverse method and damped least square method.
- Code generation ready.
How to use:
- Create the robot structure with cgr_create.
- Actuate and update the joint with cgr_self_update functions.
- If necessary, plot the robot with ncgr_plot by first calling ncgr_graphic once at the beginning of the program.
- To create the compiled MEX or DLL files, two examples of MATLAB Coder project files are provided.
Here are some kinematics problems for us to try!
