I am trying to build a URDF model in rviz for simulation purpose. I have developed a URDF model which is working fine if I move the joints manually. I am not sure if I have done the conversion from DH to URDF correctly. Can someone help?

This is the URDF and the DH parameters for these joints for Adept1 robot are

a       d            alpha     theta
0.42500       0     0       0  
0.37500       0     0       0  
0       0.30000     0       0 
0       0       1.57080     0 
0       0       1.57080     0  

Please I would like to know if I am going in the right direction. Otherwise please give me guidelines to use DH parameters in URDF. Thank you.
