Our customers use more and more robots to replace workers or traditional NC machines. This is specially the case in Aerospace, where the most important process is drilling and riveting. However in this process, the effort needed is quite important and there might be an accuracy issue when using a traditional 6 axes robot, due to the flexibility in the robot arm. To avoid this, one way is to use a parallel robot that can provide an important effort and keep a good accuracy. There are several robot manufacturers who can provide such robots, for example the German company Physik Instrumente who has the "Hexapod" parallel robot. DELMIA 3DExperience has the capability to model any kind of robots including such parallel robot, since the complex kinematics can be defined by the user in an external DLL (from a C template provided by DELMIA). When jogging the robot in DELMIA, the external DLL is used to compute on the fly the inverse kinematics (also possible for the forward kin). The advantages are: 

- the inv kin in DELMIA is accurate because it can been created by the robot manufacturer itself using the same algorithm used in the real controller

- the IP for the complex kinematics is kept by the robot manufacturer

- no performance issue

Special thanks to our partners Engrotec and Prodtex who have helped PI to create this robot model (Hexapod H845 3D and kin) in DELMIA.
