Strap a bomb to one of those things...
Maybe, but I can see China holding reservations about deploying automatous lethal drones, especially in an urban environment. Especially in the scale we will likely see such drones deployed in to clear urban areas en mass and quickly. In addition, strapping a useful sized explosive payload on these drones will dramatically reduce their range, endurance and agility. And I imagine these are fairly expensive (comparatively speaking) to just use as suicide bombs like that.
Maybe they will deploy such a version, but I think those will be used for specialist and limited applications, such as to breach and clear an enemy strong point in a position hard to reach with conventional artillery etc. Although they already got their flying hand grenade for such applications, which is probably a lot cheaper per unit.
Instead I can see such drones being used to sweep ahead of friendly troops to spot ambushes and flag enemies. Soldiers will still need to clear buildings to flush out hiding enemies, but it should be much safer and quicker with these drones as early warning.
I can also see these drones being deployed to support armoured advances to sweep buildings either side to keep all those windows and rooms secured as your forces move up.
Drones spot enemy ATGM/RPG/Sniper teams and upload position data to friendly armour or heavier armed drones, who sends HE death at flagged targets, with more drones and friendly troops moving in after to mop up anything that survives.
As drones run low on battery/ammo, they can be swapped out with backups and the entire push can advance with constant drone fleet support.
