Robot as a service in computer science education. RaaS uses existing services to compose different applications at workflow level, which significantly reduce the learning curve of robotics programming. Robot as a service Robot as a service (or Robotics as a service, RaaS) is a cloud computing unit that facilitates the seamless integration of robot and embedded devices into Web and cloud computing environment. In terms of service-oriented architecture (SOA), a RaaS unit includes services for performing functionality, a service directory for discovery and publishing, and service clients for user's direct access. The current RaaS implementation facilitates SOAP and RESTful communications between RaaS units and
