The Ardomower chassis does not have a rounded front. That means that all ultrasonic sensors look into the same direction. So I created a front that is slightly round.

It has mounting options for the three ultrasonic sensors and an MPU6050 sensor. Some grinding is perhaps necessary so that the sensors fit into the wholes.

I have a model for an MPU9250 sensor holder as well. Drop me a note in the ardumower forum.
