Herein a method for object tracking and interception for applications in arm robotics is presented. Generality of five and six degree of freedom robots has traditionally been lost due to focus on pre-programmed dead-reckoning centric algorithms. the method presented herein utilizes high speed software engineering techniques in conjunction with image processing algorithms to produce a viable and extensible object tracking platform.

this paper aims to leverage knowledge and experience, gained from the well-established Automated Guided Vehicle (AGV) industry, to highlight key hazards and solutions that may be considered in the risk assessment and risk reduction of large autonomous mobile service robots in orchards. there are notable differences between orchard environments and the warehouses or factories, where AGVs operate, including the presence of uncontrolled growth, exposure to the weather as well as the slope, softness, cluttered and undulating nature of terrain in orchards. However, there are also many similarities in the technologies used, the basic navigation tasks that have to be performed and the nature of the hazards that arise. this paper discusses these similarities and differences in relation to key parts of AGV standards, EN 1525:1997 and ANSI/ITSDF B56.5-2012.

the models of software implementation of the system of cryptographic protection of information (SCPI) withthe given characteristics are described. this system is intended for using in systems and networks of information transmission and storage. In the created system of cryptographic protection of information, the nonconventional algorithms of encryption and digital signature developed on the basis of nonpositional polynominal notations (NPNs) are implemented. Synonyms of NPNs are notations in residual classes. Given characteristics are the length of the message or the digital signature, as well as cryptostrength of algorithms.

Bat wings contain dozens of joints that enable the animal to perform aggressive maneuvers by means of changing the wing shape during flight. there is evidence that the inertial forces produced by their wings during flapping have a key role in the attitude movements of the animal, i.e. aerial rotations. In fact, bats efficiently generate net body forces to manoeuvre by taking advantage of their large wing-to-body mass ratio. In this paper, the following question is formulated: Could a Micro Aerial Vehicle (MAV) inspired by the biomechanics of bats take advantage of the morphing-wings aimed at increasing net body forces? Using BaTboT, a novel bat-like MAV with highly articulated wings actuated by shape memory alloy actuators, our goal is to quantify the effects of different wing modulation patterns on the generation of net body forces. Experiments are carried out to confirm the important physical role that changing the wing shape enables: the contraction time of the wings (upstroke) should be faster than the extension time (downstroke), taking about 37.5% of the wingbeat period. this modulation pattern has enabled a lift force increment of 22% (from L = 0.92N to L = 1.12N), abrupt drag reduction (from D = 0.22N to D = 0.11N) and also an increase of net body forces (Fnet) about 28% compared to those wing modulation patterns defined with equal periods for contraction/extension. these findings can be useful for accurate dynamics modelling and efficient design of flight controllers applied to morphing-wing micro aerial vehicles.
