Insight and leverage from prior project work identified the need for haptics; the inspector’s sense of touch is often used in bridge assessment. Haptics’ adoption in medical robotics shows potential for applications in remote inspection and maintenance. For example, surgeons employ haptic-based manipulators to both probe and operate minimally-invasive procedures. Such manipulators augment the surgeon by assessing areas that are difficult to see or reach with conventional tools. Likewise, envisioned is the augmentation of bridge personnel by providing a haptics-based aerial manipulator. Such a manipulator would reduce needs to ascend elevated structures like under bridge decks and cabling.
There is recent work that uses haptics in aerial manipulation. But these center on autonomous multi-drone flight formation for aerial shows or cooperative object delivery [1] [2]. The haptics research here is relatively straight-forward [3]. The sense of touch is used to provide spatial distance between drones. By contrast, this proposal’s novelty and merit are centered on human-in-the-loop aerial manipulation. The notion is that the expert bridge worker remotely configures the aerial manipulator to “probe” areas of interest and “operate” maintenance procedures.
This Year 4 proposal integrates haptics, augmented reality (AR), and drone-mounted arm. The specific objective is to characterize haptics and AR for their applicability to perform remote probing (i.e. inspection) and operation (i.e. maintenance).
Scope of Work in Year 4: The objectives of this study are to test, evaluate, verify and validate haptics-based aerial manipulation. Realizing such objectives would yield new capabilities for remote bridge inspection and maintenance. The tools and techniques would leverage bridge personnel expertise and introduce a new paradigm of human-in-the-loop aerial manipulation. This is akin to the advances and adoption found in medical robotics for minimally-invasive surgery. |
