Stick Insect Locomotion

This website contains all data and supplementary information about a collaborative project by the CITEC workgroups Biological Cybernetics (V. Dürr), Semantic Computing (P. Cimiano) and Computer Graphics (M. Botsch). The main purpose of this project is to disseminate research data on comparative and adaptive locomotion in a way that is both intuitive, accessible and scientifically appropriate. The data set is open access and free of cost.

The project takes account of the fact that in recent years, experimental data on natural, un-restrained locomotion of animals has strongly increased in complexity and quantity. Since much of this data is of great value for the development, modelling and benchmarking of technical locomotion systems, suitable data management, documentation and visualization are essential. Here, we propose a data format that is equally suitable for scientific analysis and sharing through web repositories. Two data models are used: a relational model (SQL) for efficient data management and mining, and the Resource Description Framework (RDF), releasing data according to the Linked Data principles and connecting it to other datasets on the web. Moreover, two visualisation options are presented, one being a photo-realistic rendering, the being plain but versatile cylinder-based 3D-models.

Our dataset comprises 36 example trials of walking and climbing insects. Three species of stick insects (Carausius morosus, Aretaon asperrimus and Medauroidea extradentata) were used. For each one of these species, several publications on locomotion behaviour and/or motor control have been published. In the experiment, animals were left to walk/climb across a set of stairs. Insects were labelled with 18 to 20 reflective markers of 1.5 mm diameter, and motion-captured using a Vicon MX10 system with eight T10 cameras (Vicon, Oxford, UK).
