Hi,
I am working with Iiwa(7 DoF) + Omnirob(Omnidirectional platform). My task is making them fullfill mobile manipulation tasks, this means making the platform and arm move synchronously for a certain task.
In order to plan the trajectory I am using moveit. For the planning of the platform trajectory we have two options:
1. Creating a P,P,R joints to define the movement of the platform. Each prismatic joint would refer to X and Y and the revolute would be the theta movement.
2. Define a virtual planar joint from base to /odom_combined.
In my case I used the {P,P,R} joints to plan the trajectory. So basically I am planning for 3(base) + 7(arm) joints group in Moveit.
Once the plan is done I would have a trajectory in {X,Y;Theta; T} for the base, and a similar one for the arm with each Joint.
**My problem comes now.**
As far as I know, there is no any controller for the base of the robot that allows you to provide a trajectory(vector of positions with time stamp), but only we can provide a path, as move_base does.
I wonder if anybody knows any controller for omnidirectional platforms in order to provide a trajectory created in moveit {X,Y,Theta,T}. In case not, whats the usual approach for omnidirectional mobile manipulators for synchronous base-arm manipulation?
Thanks alot!
