[Vehicles] Self-Propelled Backpack
A particular character plans on having a survivalist "go-bag", so that whatever happens to the infrastructure the ship or colony they're on, they'll be able to survive with their own resources for at least a couple of years. (Setting is roughly TL10, STL/interplanetary-scale, and for our purposes, lacks superscience.) Said character wants to take advantage of modern tech, so the go-bag can move on its own to stay near them, while being unobtrusive about it... and if they get knocked unconscious, at least stuff them into their vaccsuit and turn on its life-support. And, if possible, still work as a backpack, to be able to be carried with even more discretion than a backpack-sized bot scuttling around in the background.
Drawing on a bit of a mix of 4e and 3e stats, here's what I've got so far; any obvious improvements to be made? * Contents: - TL11 Survival Food Factory ($10k, 10 lbs, C/30 meals (360 kJ/meal), LC4; 10 meals' flavor additives, 0.5 lbs, $1). - Light vacsuit (5.8 lbs, $7,460). - Air-cycling pack (3e TL10 NPU, 0.2 kW, 1.2 lbs, 0.012 cf, $2k, 2 years; 3e TL11 Full Life System, 20 lbs, 1 cf, $500, 0.1 kW.). - Solar recharger (3e: 10sf, 1 lb, $300, 0.8 kW at 1 AU; folding panel, 10 sf, 2 lbs, 0.04 cf, $50). - Battery (C-cell, $10, 0.5 lbs). - Misc: 9 lbs - Total: 50 lbs * Vacsuit: built as Pyramid 3-96 armor; lightest possible emergency vaccsuit, TL10: Full Coverage (21.35 sf), Bioplas, DR 15 (vs pierc/cut, DR 5 vs other), Optimized Fabric: 3.8 lbs, $4,800; flexible (don in 4 seconds), concealable (can be disguised as swimwear, lingerie, other diaphonous clothing), Radiation PF 0.5.

Re: [Vehicles] Self-Propelled Backpack
I think I don't want this as gear so much as I want to make it my next sci-fi PC: A robot go-bag whose owner is dead.

Re: [Vehicles] Self-Propelled Backpack
Feel free; I once cobbled together a mailman-themed recolour of WALL-E (DAN-E: "Deliver Anywhere Nearby, Earth-Class") for similar boxy-carryall-robotic shenanigans. :)

** DAN-E Robot type: Deliver Anywhere Nearby, Earth-Class: DAN-E. BnL didn't spend lots of money inventing the WALL-E chassis from scratch, they just took one of their existing designs and slapped a trash compactor into it. Most of DAN-E's boxy torso is taken up with a modular slot; the original specs called for an empty volume to hold either a pile of letters and parcels, or a battery for those more rural deliveries. Other than usually being painted mailman-blue instead of garbage-truck yellow, and WALL-E having a little more junk in the trunk (ahem), the two designs are nearly indistinguishable.

Re: [Vehicles] Self-Propelled Backpack
I can see this getting on very well with a certain chest of Mr Pratchett's - sufficiently advanced technology indeed.

... Whoops. I just noticed that should have been 21 HP in the GURPS stats (bringing the final cost down to [75]). Ah well, either way, it's still a pretty rugged design, and can take a lot of abuse.

Re: [Vehicles] Self-Propelled Backpack
Object carriers are perfectly useful, it just turns out that wheels work fine for most situations we care about.
