Stair Climbing via Successive Perching

IEEE/ASME Transactions on Mechatronics, 2015
Stairs are a primary challenge for mobile robots navigating indoor human environments. Stair climbing is a useful, if not necessary, capability for mobile robots in urban search and rescue, security, cleaning, telepresence, elder care, and other applications.

Feeding-Related Skull Structures of Climbing Perch Anabas testudineus (Anabantidae)

Journal of Ichthyology, 2023
The feeding-related skull structures are described and occluding elements of the upper and lower regions of the buccopharyngeal cavity are analyzed in climbing perch. At each side of the neurocranium, the transverse process of the parasphenoid with four or five large conical teeth oppose the hypobranchial 3, and the medial teeth of the parasphenoid ...

Scanning electron microscopy of the heart of the climbing perch

Journal of Fish Biology, 2001
The air‐breathing climbing perch Anabas testudineus has two ventral aortas, one directs blood through well developed anterior gill arches into the suprabranchial chambers and back to the heart and the other sends blood through rudimentary shunt‐like posterior arches and onto the systemic circulation.

Terrestrial locomotion characteristics of climbing perch (Anabas testudineus)

Journal of Experimental Biology
ABSTRACT The evolution and utilization of limbs facilitated terrestrial vertebrate movement on land, but little is known about how other lateral structures enhance terrestrial locomotion in amphibian fishes without terrestrialized limb structures. Climbing perch (Anabas testudineus) exhibit sustained terrestrial locomotion using uniaxial

Perching and vertical climbing: Design of a multimodal robot

2014 IEEE International Conference on Robotics and Automation (ICRA), 2014
We present a robot capable of both (1) dynam- ically perching onto smooth, flat surfaces from a ballistic trajectory and (2) successfully transitioning to a climbing gait. Merging these two modes of movement is achieved via a mechanism utilizing an opposed grip with directional adhesives.

Accessory respiration in the climbing perch anabas scandens

Hydrobiologia, 1976
Analyses of gas in the chamber of the accessory organ of Anabas scandens were made by keeping the fish forcibly under running or stagnant water for various times upto 15 minutes immediately after it took a fresh gulp of air. The percentage of O2 and CO2 decreased variously as time of submersion increased.

Climbing perch Anabas testudineus avoid expanded polystyrene pellets ingestion

2022
Resumen La perca trepadora Anabas testudineus está muy extendida en las aguas continentales de Vietnam y según su ecología podría tener contacto con un residuo plástico flotante. Los fragmentos de poliestireno expandido (eps) detectados en las aguas dulces de Vietnam en las provincias de Khanh Hoa, Lam Dong y Phu Yen.
