scAnt—an open-source platform for the creation of 3D models of arthropods (and other small objects)
2021
PeerJ
Preserved Fulltext
We present scAnt, an open-source platform for the creation of digital 3D models of arthropods and small objects. scAnt consists of a scanner and a Graphical User Interface, and enables the automated generation ...
As a result of the exclusive reliance on generic hardware components, rapid prototyping and open-source software, scAnt costs only a fraction of available comparable systems. ...
ACKNOWLEDGEMENTS The authors are grateful for the kind support and expert input from René Bulla, in particular in respect to 3D modelling and processing of visual data. ...

This paper presents a new statically balanced walking technique for a robot-crawler. The gait design and the control of the robot crawler aim to achieve stability while walking. ...
In order to reduce the risk of stability loss while walking, a measure for the robot stability (so-called stability margin) is typically used in the gait and motion planning. ...
The data captured is then transferred to the Motion Capture Analysis tool which models a 3D view of the object captured. ...
