 So I've made some progress. In the robot param file (waffle_pi.yaml), if I change line 29 from

     robot_model_type: "differential"

 to

     robot_model_type: "nav2_amcl::DifferentialMotionModel"

then rViz will launch and initialize properly.

However I don't seem to be getting a local costmap, even though rViz is confugured to display one. I'm not seeing any clear errors in the logs.
