We did a lot of modeling in 2008 trying to understand how to improve dynamic performance. We also experimented with different wheel types. Over the last few years, I have been working with skid steer vehicles with similar aspect ratio (length/width), and I was introduced to a recommended ratio of 20HP/Ton. Basically 1HP/100lbs or 1.1KW for a 150lb robot (120(robot)+12(battery)+15(bumpers)=147lbs) which is perfect for the 4 CIM combo.
