There is not specific sensor on the Turtlebot that allows querying it's weight. In principle it might be possible to infer robot payload from things like motor current required to move, odometry response etc., but that requires a full set of experiments, reproducible ground conditions etc., so not sure how viable it is.

I think the most reliable way would be using and Arduino to interface a electric scale or load cell and write out the data to ROS via rosserial_arduino. If you search for "scale arduino" or similar terms, you should find many (pretty cheap) options.
