Robotics trainer

I'm looking for an experienced robotics trainer to provide hands-on training to an advanced-level group. I'm open to recommendations on what robotics platform or system to use for the training, and prefer that the training takes place in person. The trainer should have a thorough understanding of robotics in order to effectively teach the material and be able to accommodate any questions the participants may have. I'm looking for someone with excellent communication skills as well as the ability to provide comprehensive instruction. A friendly and patient demeanor is a must for a successful training program.
