65. Proposed solution Hybrid actuation
66. Proposed solution Hybrid actuation
67. Proposed solution Hybrid actuation
68. Discussion Hybrid actuation 1. Obtaining background knowledge 2. Triggering REST actuation 3. From a subscription to result to goal More general from task to result.
69. Conclusions
70. Conclusions and Future Work Seamless reuse in simple scenario github.com/gomezgoiri /reusingWebActuatorsFromSemanticSpace Further investigation with more complex scenarios is needed Is the translation between the subscriptions and the goal always possible? If the plan has 2 or more paths to achieve a goal, which one should we chose? What if two different actuators from space-based and rest-based actuation can be activated?
