Skitarii (Tech Guard) codex?

Punisher Cannons are on a version of the Leman Russ in the Imperial Guard codex, I believe. At least if it's what I think you're talking about.

Yup, definitely planning ot keep their S and T at 3 by default. I thought doing it through Bionics instead of just boosting their base stats would allow them to still be weaker than Space Marines but stronger than Guardsmen, since they get some of the benefits (harder to wound) but not others (still suffer instant death on S6.)

An old edition style Armory list that applies to the Troop choices. Hmm... while it might make it a little more work to put specific lists together, I definitely agree, it's a lot more fitting for the Adeptus Mechanicus.

Here's an idea to keep robots stupid.

Cortex
Robots are only able to follow the most basic of commands, and cannot easily adjust these commands to as the battle rages on. At the beginning of your turn, each robot unit that isn't already obeying a command must be given one of the following commands. Unless given the "Stop" order, it must act according to the order given until it has been completely performed once.

-Move: Place a marker on the table to indicate the point you want the robot to move to. It must move and run as far as it can in a straight line each turn until it reaches that point.
-Fire (Weapon): The robot approaches the target until the specific weapon selected is at its maximum range, then fires.
-Attack: The robot approaches the target until it can be assaulted, then may assault.
-Guard: The robot remains stationary and fires at the nearest target every turn until given a "Stop" order.
-Stop: This order may be given to a robot already obeying a previous order. The robot cancels its last order and becomes idle. It does nothing that turn, but may be issued a new order at the start of the next turn.

Lexicanum says they opperate in "maniples" of 3-5 with a Legio tech-adept commanding them, so I'd say commands can only be issued as long as there is a tech-adept in the unit. If he is killed or leaves by some other means, the robots become idle once they complete their most recent order and cannot be given new orders until a tech-adept joins them again. (Of course, if you just wanted them to hold an objective, you could just give them a Guard order, then the tech-adept would be free to do whatever they want.)

Since I'm bored, I'll do another... Both of these are Troops Choices, mainly because the Skitarii have only vehicles in their Heavy Support, and mostly vehicles in their Fast Attack.


Wargear!

Skitarii Combi-Weapon
Functionally identical to other Combi-Weapons, but the main component is a Skitarii Lasgun.

Skitarii Lascannon
The tri-cyclic Skitarii Lascannon may punch through the thoughest armours with surprising ease.

Skitarii Multi-laser
Multi-spectral coating lowers the effect of atmospherics on the laser bloom, increasing the range of the weapon.
48" range, S6, AP6, Heavy 3

Skitarii Plasma Cannon
The Skitarii version of the Plasma Cannon is equipped with a recently discovered laser cooling system. In the event of a Gets Hot!, the Adept attempts a save to shut down the weapon and avoid the overheat. For this purpose, the Adept's save is improved by 1. It is otherwise functionally identical to the Plasma Cannon.

Cameleoline Armorweave
Functionally identical to a camo cloak, but of much greater quality. Gives the Stealth USR.

Still bored. Time for some vehicles!


Wargear!

Hailstorm Missile
Single-use weapon system fitted to some Skitarii vehicles. A Hailstorm Missile is a krak missile with unlimited range that can only be fired once per game. They are fired at BS4, and are treated as an additional weapon. The missile attack type is top-attack, and will always affect the side armor.

It is a foot wider than a Chimera, and has a a second turret instead of the hull-mounted weapon. The turrets are side by side, but do not have 360 coverage. The transport has 6 fire points instead of the Chimera's 5, three in each turret.

Each rack carries 3 missiles.

Since I'm still so incredibly bored...


Special Rules

Selective Fire
The unit has an arsenal of weaponry at it's disposal, but may only use one ranged weapon in each Shooting phase.


Wargear

Thudd Launcher
An area denial artillery weapon with impressive target saturation abilities.
12-48" range, S5, AP5, Heavy 4, Barrage, Blast

Melta Shell Launcher
A hybrid cannon-missile launcher, capable of firing the incredibly complex Melta Shell.
12-48" range, S8, AP1, Heavy 1, Melta, Blast

Shattersky Artillery
This massive artillery piece fires six-tonne Shattersky shells. The shells are equipped with grav-chutes, and are primed to detonate in the air in a two-stage explosion. At first, a small blast takes place that splits the weapon apart. Two seconds later, the main charge detonates in a massive shockwave and fireball that obliterates everything in it's path and makes a mockery of cover or defenses. Cover saves may not be taken against the Shattersky Artillery attack.
24-96" range, S8, AP2, Ordnance Barrage 1, Large Blast
