2 hours of battery life seems pretty short. The tablet portion should probably have a separate battery and can then have a 7-10 hour battery life, like most tablets these days. Maybe they should add a wireless charger to the package. When the batteries get down to 10%, the unit automatically wheels back to the charging station. Now, if there's a sleeping dog in the way, or a box or something, then the robot's out of luck, but otherwise it just takes care of itself, like a person going to the toilet once in a while. The other obvious thing the product needs is a robotic arm. So useful. Obviously, bringing the medicine to a bedbound patient springs to mind, but the uses are really unlimited.
