I don't think Ukraine's ground drones could thrive in a rapidly moving frontline for most of the tasks noted in an article. But while the front is stalemated, the UGVs certainly help cope with the situation.
Ukraine tries to reduce casualties by turning over some missions to ground drones:
On a battlefield swarming with deadly Russian drones, Ukrainian soldiers are increasingly turning to nimble, remote-controlled armored vehicles that can perform an array of tasks and spare troops from potentially life-threatening missions.
The Ukrainian army is especially eager to deploy what soldiers refer to as “robots on wheels” as it faces a shortage of soldiers in a war that has dragged on for more than 3 ½ years. The vehicles look like miniature tanks and can ferry supplies, clear mines and evacuate the wounded or dead.
I think that the key reason for these ground drones is that it is a static battlefield. Even more so than with aerial drones, I think Ukraine's use of small wheeled drones for various tasks simply cope with the static battlefield.
