The provided passages discuss primary results on dynamic quadrupedal legged locomotion and hovering for the Husky robot v.2 [1]. However, to demonstrate true multi-modal prowess, critical performance aspects or transitional maneuvers that are not explicitly mentioned but would be essential to evaluate include:
The ability to leverage multimodality to negotiate complex environments by using both legged and flight modes to maneuver around and over obstacles [3]. Additionally, the development of a unified controller integrating thruster inputs and ground reaction forces for enhanced thruster-assisted locomotion, encompassing tasks like narrow path walking, slacklining, and steep slope locomotion, is crucial [3]. Recovering from propeller fault conditions by taking advantage of movable propeller arms in flight mode is also a vital capability that remains to be tested [3]. These aspects are important for showcasing the robot's versatility beyond basic locomotion and hovering, particularly in challenging real-world scenarios.

Email: a.ramezani@northeastern.edu Abstract Multi-modal ground-aerial robots have been extensively studied, with a significant challenge lying in the integration of conflicting requirements across different modes of operation. The Husky robot family, developed at Northeastern University, and specifically the Husky v.2 discussed in this study, addresses this challenge by incorporating posture manipulation and thrust vectoring into multi-modal locomotion through structure repurposing. This quadrupedal robot features leg structures that can be repurposed for dynamic legged locomotion and flight.…
n-made obstacles (e.g., traffic), quickly reaching the vicinity (e.g., building rooftops or balconies) of the customers. There, the robot lands nearby using a powered descent wherever level ground, gaps in the forest canopy, or safe proximity from humans it can find. Now, the legged mobility closes the final distance for the last-mile delivery challenge using its precise and safe legged locomotion capability. There are already many promising multi-modal works [ 8 , 9 , 10 ] . The most common being integrated on the quadrotor platform. But only a few studies exist that show re-configurable…
Husky’s design possesses thrust-to-weight and leg loading ratios that support both flight and dynamic legged locomotion. While these results suggest that the design concept of structure repurposing is meaningful, other capabilities – such as carrying extra payloads (e.g., sensors for perception and autonomous navigation) – remain to be tested and validated. Hence, our future research will focus on: 1) Demonstrating our robot’s ability to leverage its multimodality to negotiate complex environments (e.g., using both legged and flight modes to maneuver around and over obstacles); 2) Developing…
enables locomotion where wheeled locomotion would be impractical, albeit with the drawback of reduced energy efficiency. Alternatively, aerial robots [ 3 ] are well-suited for higher speeds, larger distances, and surmounting obstacles that prohibit all ground locomotion such as waterways, canyons, fences, etc. By proposing a robot design that can morph between legged and aerial mobility, the capabilities of each mode may be harnessed to create a highly versatile robot [ 4 , 5 ] . Figure 1: This work explores multi-modal dynamic-legged-aerial locomotion through appendage repurposing. To…
to be used as a surveillance robot, uses bat wings for gliding and small compliant wheel-legs for moving on the ground. The body of the robot is built using carbon fiber and weighs 100g, can carry a sensor payload up to 20% of its weight, can crawl, fly, and land. Deployable Air and Land Explorer Robot (DALER) by [ 30 ] mimics the locomotion of Desmondus Rotundus, also known as the vampire bat. The robot needs to be launched to start flying but exhibits terrestrial and aerial locomotion just using wings. RoboFly [ 31 ] is an insect-sized multi-modal robot that can walk, fly and move over…

- Explain how the "conflicting requirements" for ground and aerial locomotion challenge traditional robot design, and how "structure repurposing" fundamentally addresses this conflict in the Husky v.2.
- Beyond defining "posture manipulation" and "thrust vectoring," describe *how* these specific mechanisms integrate with "structure repurposing" to enable the robot's legs to effectively serve dual functions for both walking and flying.
- If "structure repurposing" is the core innovation, what are the potential long-term benefits or drawbacks of this design philosophy regarding robot complexity, maintenance, and overall energy efficiency, compared to using separate, dedicated components for each mode?
- Imagine designing a multi-modal robot without "structure repurposing." What alternative design strategies might emerge, and what inherent trade-offs (e.g., weight, complexity, performance) would they present compared to the Husky v.2's approach?
