A Novel Generalized Nonholonomy Criteria and Physical Interpretation of Holonomic/Nonholonomic Constraints of a Free Flying Space Robot with/without Interaction with a Flying Target Satellite
... The physical characteristics of the nonholonomic con- straints are exhibited by the fact that even if the manipu- lator joints return to their initial configuration after a sequence of motion, the vehicle orientation may ...

Migratory directions of free flying birds versus orientation in registration cages
... The directional scatter of the birds in Emlen funnel experiments was considerably higher than that of radar-tracked birds in spite of a broader variation in the species composition of free-flying birds. ...

Manipulation Control of a Flexible Space Free Flying Robot Using Fuzzy Tuning Approach
... In this paper, first the system dynamics is virtually partitioned into two rigid and flexible portions, and a convenient model for control purposes of rigid-flexible multi-body systems is developed. Next, to perform a ...

Automated hull reconstruction motion tracking (HRMT) applied to sideways maneuvers of free flying insects
... Flying insects perform aerial maneuvers through slight manipulations of their wing motions. Because such manipulations in wing kinematics are subtle, a reliable method is needed to properly discern consistent ...

3D reconstruction and analysis of wing deformation in free flying dragonflies
... The cameras are linked using a hardware tether and synchronized using a master–slave system with a camera response time in the nanosecond range. They are triggered by a laser controller that transmits a 5V ...

Adjustments of wingbeat frequency and air speed to air density in free flying migratory birds
... While flying under constant atmospheric conditions in a wind tunnel, they increased their air speed by an increase in their stroke amplitude and not in their wingbeat ...

Respiratory water loss in free flying pigeons
... respiratory quotient (RQ) in flying pigeons was close to 0.73 both in wind tunnel experiments (Biesel and Nachtigall, 1987) and in free flight (Bordel and Haase, 1993; Schwilch et al., 1996). Based on the ...

Heart Rate, Respiratory Frequency and Wing Beat Frequency of Free Flying Barnacle Geese Branta Leucopsis
... A two channel radio-transmitter was implanted into these geese so that heart rate and respiratory frequency could be recorded before, during and after flights of relatively long duration[r] ...

In flight corrections in free flying barn owls (Tyto alba) during sound localization tasks
... Barn owls localize a stationary auditory target with high accuracy. They might also be able to hit a target that is intermittently moving while the owl is approaching. If so, there should be a critical delay before ...

A model of visual–olfactory integration for odour localisation in free flying fruit flies
... Other than the simple high-level model presented by Frye and colleagues (Frye et al., 2003), ours is the first closed-loop model of odour localisation behaviour of an insect flying in still air to be proposed, to ...

A shot in the dark: the silent quest of a free flying phonotactic fly
... The accuracy of phonotaxis, measured as the distance between the landing position and the centre of the loudspeaker, did not improve for successive flight sequences. Naive females were able to detect and locate the sound ...

Smart shape changing structures for space based solar power applications
... The mass of each colony is assumed with 100kg and an stored volume of 0.8m 3 of which 0.5m 3 are the flexible deployable and 0.3m 3 are the rigid components. Experiments at the University of Strathclyde [14] showed that ...
