A robotic system for applying a volatile fluid to a work-piece comprising a support structure configured to mount at least one spray nozzle while facilitating motion of the nozzle in multiple degrees of freedom. An encoder senses a position of the spray nozzle and issues a position signal indicative thereof. A pneumatically-driven motor effects displacement of the spray nozzle on the support structure along each degree of freedom. A controller disposed outside the boundaries defined by the structural support, is responsive to the position signals for controlling the pneumatically-driven motor to displace the spray nozzle while dispensing the volatile fluid. The pneumatically driven motor and the isolated spatial position of the controller prohibits a source of ignition for the volatile fluid sprayed by the nozzle.
