I'm using a translator so please ignore the grammar, thanks.
I think Jadebot can be something much bigger and more profitable for arenanet, Jadebot is cute and cute things sell, he should follow us around the map just like the miniatures, making interactions and being customizable with paints and skins just like the mounts, the core and the chips/sensor should be moved to our character's equipment next door of accessories to make it simpler.
Batteries are ugly and shouldn't be scattered in forests, add jade magic(floating orbs like volatile magic) to fast collect for energy and add offensive and defensive buffs for united legions waystation(only works in Cantha), so we don't have to stay looking for buffs when we need them most.
Jadebot could have an emote system to interact with other players, if we want to send a heart then a floating balloon appears over the jadebot for everyone to see. Emotes could be sold or collected in-game just like in league of legends.
The personal waypoint is awesome but they should consider making it permanent or adding a duration time instead of a single use.
That's it. There are so many things that can be done to make it more interesting, hope arenanet take a look.
