"Android Butler" I was ill and slept all day and only had a few hours to do it, so I had to do a dumb joke instead of the more sophisticated idea i went to bed ruminating upon.
"Companion Android" i felt it was redundant and not specific enough of a prompt
"Caregiver Robot" Autobot Chief Medical Officer Ratchet. I spent all day on him. i was exhausted.
and turn! not sure about the wheels. or the backpack. i have tweaked him since, not least of which to split off an Ironhide model, but this is as he was within the timeframe of the challenge.
"Security Robot" just a simple trashcan design. may possess stunguns and beanbag launchers behind the doors on it's torso. also has a hat! :)
"Exploration Rover" her battery is low and it's getting dark... ;_;
