MPC for a mecanum wheeled model using Drake

I'm new to MIT Drake, I was using CasADi (ipopt) for a mecanum wheeled model for MPC.

In CasADi, I can create a symbolic variable for the optimization parameters (i.e., initial state and target state).

Then use it to compute the error in state, how can I get an equivalent functionality in Drake?

I've definitely seen mechanum wheels work in drake, but doing trajectory optimization for them requires some thought. For most every wheeled robot trajectory optimization, you want to use a minimal coordinates model. I discuss that briefly in the ballbot example in the notebook associated with http://underactuated.csail.mit.edu/acrobot.html

And for formulating your MPC, I would recommend the notes in http://underactuated.csail.mit.edu/trajopt.html
