They say 'The Black Knight uses many automotive components from the Bradley to reduce costs and simplify maintenance.'
However, that's most definitely an M113 chassis it's sitting on - Bradley's have 6 roadwheels, 113's have 5. Having served on both, that's a 113 chassis.
From here:

it looks like the weapon systems/targetting etc. are mostly Bradley-based, and that this unmanned vehicle is controlled back from a Bradley BC position:
"The Black Knight’s turret is equipped with operative components already fielded by the Bradley Combat Systems program, providing synergy between the current force and the future force"
and
"Gun and turret position, as well as information from the Commander’s Independent Viewer and the improved Bradley Acquisition System, can be viewed from the Bradley’s Commander’s Crew Station. As Soldiers dismount, they take the Dismounted Control Device (DCD) along to continue operating the Black Knight, receiving information on the single screen on the DCD"
Pretty neat concept, if an ugly vehicle
