The data tree is organised first by bat species and then by the date on which data was recorded. Then comes the index number for one particular flight. Since most flight sequences were recorded by many pieces of equipment at the same time, a record of which recordings belong to the same flight is very important. These .xls files are found under each date.

Under the index number comes a partner abbreviation. Each partner in the ChiRoPing project uses different equipment so uploads different data in different file formats and with different sequence numbers. This page tells you what data is available in what format where. Note that only some flights have a complete set of data, since only some flights were recorded by all possible equipment.

There are also files/folders labeled "artificial" containing non-bat data, eg from preliminary investigations and eventually from the robot demonstrators; and "shape" containing the .stl files used to print the plastic bat heads.

The team from the University of Antwerp is using the 16 channel 2D Microphone Array described in deliverable 2.4.1. The audio data produced is stored in .dat format. These are binary files which contains unsigned int16 data (so 2 bytes per datapoint). This data is stored in an interleaved fashion, per channel, as it comes out of the recording system and as described in the deliverable. A matlab function that reads the data is also available.

All the settings used for the recordings, eg. number of channels, number of recorded samples per channel, trigger types, etc. are stored in an associated .xml file. The synchronisation signal used to synchronise the audio recordings with high speed video for this flight is sampled at the same frequency as the rest of the data. It is contained in the .dat files and also available in the text file sync.txt.

The team from the University of Edinburgh is responsible for the Dimensional Imaging 3D Scanner described in deliverable 1.1.2. However this data needs extensive processing before we can fully use it, so no data from this is publically available yet.

They also use more conventional stereo cameras to produce video of the flight sequences in .dvi or .avi formats. These videos have their individual frames extracted in .jpg format and packed together in a .zip file. The synch*.txt file contains the synchronisation signal allowing the audio and video sequences for this flight to be aligned.

Calibration information for each run is in a Cal* subfolder which contains the left and right calibration files in .xml format.

The team from the University of Ulm use several different types of equipment and are responsible for the bulk of the data here.

The datalogger stores detailed temperature, pressure and humidity data in excel format. The overview graph is stored as a .jpeg.

The high speed camera makes .seq files for each flight sequence. Every frame of these is then converted into bitmap format .bmp.

The Avisoft microphone produces a .wav file. This microphone is normally used in conjunction with the high speed camera, so that most folders containing a .seq file should contain a .wav file for the same event.

A Sony handycam is used as an overhead camera filming in the infrared. Its output is converted into .wma or .mpeg2 before being placed in the repository.

They also use the Antwerp array described above.

The team from SDU's Biology Institute uses a calibrated array with up to 12 microphones to collect data in parallel with the Antwerp array, in .wav format.

The team from SDU's Maersk Mc-Kinney Moller Institute uses the acoustic array recordings collected by sdub or ua to compute bat position and orientation for each emitted call. Ultimately reconstructions of the emitted calls will be available.

A presentation of the main points of the project.

2002-2005: CIRCE (Chiroptera Inspired Robotic CEphaloid; IST-2001-35144) which reproduced, at a functional level, the echolocation system of bats by constructing a bionic bat head that was used to systematically investigate how the world is not just perceived but actively explored by bats. This bionic bat head is of similar size to a real bat head to reproduce the relevant physics and consist of an emission/reception system capable of generating/processing bat vocalisations in real-time, a multi-degree of freedom mechanical system to allow realistic pinnae movement.

2005-2010: CILIA (Customized Intelligent Life-inspired Arrays; IST-2005-016039), about sensory systems based on arrays of hairs. The project aims to identify the common principles underlying the widespread use in nature of arrays of mechanical sensory cells for the extraction of meaning under adverse conditions and to make those principles available for design of engineered systems.
