One advantage of UGVs is their low cost - the parts for Hnatok's smaller machines cost less than 30,000 hryvnias ($812).
The impact of combat UGVs from both sides has been extremely limited so far, according to Samuel Bendett, senior fellow at the Center for a New American Security.
However, he said the UGV sector was one to watch, with well-educated and technologically adept volunteers, especially in Ukraine, scrambling to create new vehicles that would give their armies an advantage.
"It's this type of battlefield innovation at the tactical edge in Ukraine that's going to (bring about) eventual emerging solutions that can lend themselves to long-term survival in combat."
It is also working on higher-tech, self-driving options such as the Marker UGV, which has demonstrated AI and machine learning capabilities and has been able to traverse through controlled environments without an operator, said Bendett.
