塗装の完全自動化を達成することができながった。When applying a top coat using a paint bot like this, the amount of paint applied to the gun nozzle at the tip of the paint gun depends on the number of coats applied.
Conventionally, a mulcher used a brush to apply a solvent (shinbu) to the gun nozzle, and after periodically cleaning the gun nozzle, wiped it off with a cloth C. Therefore, even if you are using a painting bot to automate the top coating of boreholes, you will need a job name every time you clean the gun nozzle.
Complete automation of painting could not be achieved.
