I have to make a small simulation of the behavior of a robotic leg in order to observe the desired trajectories. In a simple way, I only would like to make some rectangular prisms, join them and make independent moves based on a coord table.
But I don´t know how to do it in a simple way with a language program or, I should do it in an specialized software for design?
I would program in C with OpenGL, the drawback is that you have to know the language and OpenGL. The advantage is that you have the great freedom to do what you require.
Aldo,
Every leg is a vector, and every joint angle is can be resolved into at least two angles in a basis set of some sort like a Cartesian frame, or a spherical polar frame, or cylindrical polar.
If you can mathematically write down the positions of each vertex as functions of their basis unit vectors (i,j,k), so vector A + B is a leg B joined to leg A;
(A = a1i, a2j, a3k, B = b1i, b2j, b3k )
then any language will suffice (BASIC, FORTRAN, C, Matlab, Octave) The last two will even let you not have to bother with decomposing the vectors and doing any trigonometry.
I'd do a little reading about 3D trigonometry.
