The lion kingdom last attempted to transport a DSLR in a robot 5 years ago.  It was a failure, especially without frequency domane PID controllers.  Today, DSLR's have shrunk enough that a full frame EOS RP with giant lens finally could be transported in the largest robot & the frequency domane PID controllers make the steering bearable.  It might fit in the smaller robot with enough coersion.  That leaves enough room for a government mandated mask, a shirt, & speaker.

The power consumption goes to 470mAh/mile.  It could reach 4 miles from the apartment.  The tire wear is a bigger problem with transporting heavier objects.
