type dof dom 6M90A_F 6 6 6M90A_G 6 5 6M180 5 5 6M90B_F 6 6 6M90B_G 6 5

Parameters:

type	0: 6M90A_F, 1: 6M90A_G, 2: 6M180, 3: 6M90B_F, 4: 6M90B_G

Returns:: 0 if successful, < 0 if failed

Transformation from previous to current link: move a along (previous) x-axis, rotate alpha about (previous) x-axis, move d along (current) z-axis, rotate theta about (current) z-axis. Setting the mDH parameters includes setting dof, adjusting immobile flag (all free) and dom (= dof).

The length of the vectors need to be the same.

Parameters:

theta	angle about z-axis
d	distance along x-axis
a	distance previous to current along previous x-axis
alpha	angle about previous x-axis
typeNr	0: 6M90A_F, 1: 6M90A_G, 2: 6M180, 3: 6M90B_F, 4: 6M90B_G, -1: other

Returns:: 0 if successful, < 0 if failed

Setting link length parameters requires the type to be set to 0 (6M90A_F), 1 (6M90A_G), 2 (6M180), 3 (6M90B_F) or 4 (6M90B_G). This is done using the setType or setModifiedDH function that set the mDH parameters so they can be adjusted. The length of the vector has to be four.

Parameters:

links length of the links in m

Returns:: 0 if successful, < 0 if failed

Flag for the last joint if it is free (0) or locked (1). Setting the immobile flag includes adjusting dom. Type or mDH parameters have to be set.

Parameters:

Returns:: 0 if successful, < 0 if failed
