After the surprising attrition rates of the record-bot 1.0 and 1.1, R&D decided to beef-up the chassis of the bot in order to promote survivability of the system. The 2.0 version essentially put the camera system onto a 4-wheeled base with the added feature of a retractable dome. In theory, if the bot got into trouble, it could retract it's camera into the dome and use secondary sensors to get away.

Part 1: More.
The simplicity of the 1.1 has been compromised to add the new features, meaning several new items have been added to the mix... with mixed results:

1. The command chip has been replaced with an actual low-end bot brain (after much heated debate) which gives the bot some level of logic and decision making skills. This makes the bot exploitable by several troubleshooter methods, although it now has some level of comprehension as to when it might be getting screwed with.
2. The bot now has a voice unit, which mainly will issue status reports. It can carry on a very limited conversation, but not much beyond "systems at 98%" and some discussion as to what it's currently doing.
3. The dome can be retracted into the reinforced base, which protects it from damage. The base supports a series of secondary cameras around the middle, which allow the unit to escape. It also remembers the path it took from R&D, so it can follow that trail back if needed.
4. The base has a fairly powerful set of lights in front. That's all, just lights. Hey, it's new.
5. The armor has been beefed up a bit. It's still yellow-reflec and all, but it's heftier.

Part 2: 4 wheels aren't better than 3
Something the troubleshooters might quickly discover is that the bot can no longer get up if it's tipped over. The R&D guys figured that a wider and heavier base would make it tougher to tip, and didn't see any reason to go beyond that. If it loses a wheel or gets tipped, it will try to get the troubleshooters to set it upright or notify R&D.

Part 3: Again, the inevitable...
The same problems exist for troubleshooters, although now they have three more options: Lie to it, trick it, or prevent it from moving. Or they can go with the old standby and simply destroy it. However, the bot's much tougher now, so it'll take a lot to get through the shell. The bot can also report them, so they'll really only get one chance.

Part 4: Grrrrrrr.
R&D is getting a bit fed up with lost/destroyed bots, so the troubleshooters had better have more than one clone saying it fell into a transport tube and then got shot 20 times and lit on fire by accident.
