Sentinel

Sentinel is a stock AI robot, RED ZONE's heavyweight. Possibly the weakest of the heavyweights.

It is a flipper (a bracket wedge on a DDT), and features titanium armor, 4WD Slipperbottoms on powered steering units, making it a bad driver.

Strangely, it is often seen pushing the arena wall and not coming to his enemy, perhaps bad AIing.

The DSL version of Sentinel is a flipper called Second Sentinel.

Second Sentinel has nearly no means to do damage (apart from the ramplate), but has a very good wedge and a very powerful flipper (the best of all the DSL AI HW's) that tosses heavyweights OOTA with ease.
