Advances in Bio-Inspired Robots

This book covers three major topics, specifically Biomimetic Robot Design, Mechanical System Design from Bio-Inspiration, and Bio-Inspired Analysis on A Mechanical System. The Biomimetic Robot Design part introduces research on flexible jumping robots, snake robots, and small flying robots, while the Mechanical System Design from Bio-Inspiration part introduces Bioinspired Divide-and-Conquer Design Methodology, Modular Cable-Driven Human-Like Robotic Arm andWall-Climbing Robot. Finally, in the Bio-Inspired Analysis on A Mechanical System part, research contents on the control strategy of Surgical Assistant Robot, modeling of Underwater Thruster, and optimization of Humanoid Robot are introduced

Description of a prototype gauge to measure magnitude and direction of hydrowire slope in situ between reversing bottles at all depths and under all conditions of ship drift

The discovery in recent years of vast deep oceanic currents running in a direction contrary to those at the surface provides additional evidence of our need for instrumental means to obtain accurate data on subsurface waters, particularly in little-known oceanic areas where pioneer lowerings are to be made. A description is given of a prototype messenger-operated wire-angle gauge which, used intermediately between reversing bottles, can furnish information on the direction of slope of the hydrowire and its actual degree of obliquity at a number of points. It is only the latter, of course, which can be computed from results obtained when unprotected reversing thermometers are used with the pressure-resisting type

How to stay perfect: the role of memory and behavioural traits in an experienced problem and a similar problem

This is the author accepted manuscript. The final version is available from Springer Verlag via the DOI in this record.When animals encounter a task they have solved previously, or the same problem appears in a different apparatus, how does memory, alongside behavioural traits such as persistence, selectivity and flexibility, enhance problem-solving efficiency? We examined this question by first presenting grey squirrels with a puzzle 22 months after their last experience of it (the recall task). Squirrels were then given the same problem presented in a physically different apparatus (the generalisation task) to test whether they would apply the previously learnt tactics to solve the same problem but in a different apparatus. The mean latency to success in the first trial of the recall task was significantly different from the first exposure but not different from the last exposure of the original task, showing retention of the task. A neophobia test in the generalisation task suggested squirrels perceived the different apparatus as a different problem, but they quickly came to apply the same effective tactics as before to solve the task. Greater selectivity (the proportion of effective behaviours) and flexibility (the rate of switching between tactics) both enhanced efficiency in the recall task, but only selectivity enhanced efficiency in the generalisation task. These results support the interaction between memory and behavioural traits in problem-solving, in particular memory of task-specific tactics that could enhance efficiency. Squirrels remembered and emitted task-effective tactics more than ineffective tactics. As a result, they consistently changed from ineffective to effective behaviours after failed attempts at problem-solving

Resettlement of Koreans and their Role in Development of Agriculture of Primorskaya Oblast in the Latter Half of the XIX - the Early of the XX Century

In the article on the basis of archival material and historical sources attempt to study questions of resettlement of Koreans to the south of the Far East of Russia in the latter half of XIX - the early of the XX century, the reason of migration and adaptation of the Korean immigrants on the new location is made. Continuous resettlement process from Korea to Primorskaya oblast (at the present time – Primorsky Krai) is considered, its dynamics and numerical indicators. Vast majority of the Korean immigrants were engaged in agriculture. Features of farming by the Korean immigrants are investigated, considering use of the agricultural experience which is saved up in Korea, the country with similar climatic, soil conditions. The question of the farming, the Korean agricultural stock, specifics of cultivation of traditional Korean grain crops are studied. One of the directions of agriculture of Koreans – silkworm breeding, its organization and results of production is investigated. It is noted that introduction to an agricultural turn of those lands which the Russian peasants considered unsuitable for agriculture; bed-grown way of processing of the land; variable system of landing plants; receiving more big crops of all species of agricultural plants, than the Russian peasants had; distribution of new agricultural plants among the population of Primorskaya oblast promoted effective farming and its development. The question of borrowing Russian peasants' practices by the Korean immigrants– cultivation of new species of plants – oats, wheat, a rye – for sale, use of agricultural stock, horses is studied. The mutual exchange of the saved-up experience and knowledge in different branches of agriculture allowed reclaiming the South of the Far East of Russia effectively. Keywords: Koreans migration, Primorsky Krai, agriculture, arable farming, silkworm breeding. JEL Classifications: M55, Q1
