(It won't let me do more than one photo so I could only do the photo of the human space craft, but I can put the photo of the robot spacecraft here)

The differences between the spacecraft for humans, and the spacecraft for robots that I drew are that the humans need more room because as you can see in the bottom parts there is storage places for water, energy, waste and the humans need lots more room because they need to sleep, so a place for sleeping, and a bathroom, they also need a place for exercising so that needs even more room, and they need a cockpit, and humans need oxygen, which means they need oxygen tanks, and air vents so that leaves us with a huge spacecraft, whereas the other spacecraft for the robot only needs a small space for the robot, and the robot doesn't need to sleep, eat, use the bathroom or exercise, all it needs is solar panels for energy so it's much easier.
