They is mBot / BioBot and a few other basic bots based from the UDO source, although these will almost guarantee that you'll end up being banned.
They is PixelBot which is pretty safe,

Not used this myself; as its a Pixelbot, I'd imagine it won't run from enemy's either.
Want my advice?... Spend €20 and get kBot, it's worth it, and if you don't want to spend money, use valhalla.
No matter what bot you use; you're going to get popped by enemy, I do with kBot, you're always going to end up being jumped, and be too far away from port to escape, just get the drone repair chip from trade, stick it on both configs, and you're good to go. The GG spins you pick up from boxes will give you enough repair credits to prevent you losing uri from being popped.
