As robots become more connected and autonomous, machines may need to interact with charging services, software, logistics and maintenance systems without human approval for every small transaction.
A wallet is one possible interface for machine-controlled value, but the harder problem is governance: who owns the wallet, what can the robot spend, how are permissions limited and how can activity be audited?
Blockchain can provide a settlement and identity layer for machine-to-machine commerce, while AI and robotics provide the intelligence and physical action.
The result could be a future economy where software agents and physical machines participate in controlled, verifiable transactions under human-defined rules.
