there are plenty of ways that this could be adapted to a robot. You need to provide an example of what you want do though. . . do you want to go way complicated or simple?
for example, you could use the transducer to tell the robot when it is 5 inches from the wall. the robot would then be programmed to go off in some other direction.
The problem though is that all of the calculations would be done digitally, so in order to feed into the robot how far away it is from the wall, a way to convert those digital signals to signals that can be used by your robot would hav to be obtained. thats not my field though :lol:
