Input Space Bifurcation Manifolds of RNNs (2009)

Robert Haschke, Jochen J. Steil

Abstract. We derive analytical expressions of local codim-1-bifurcations for a fully connected, additive, discrete-time RNN, where we regard the external inputs as bifurcation parameters. The...

Abstract Input Space Bifurcation Manifolds of Recurrent Neural Networks (2008)

Robert Haschke, Jochen J. Steil

We derive analytical expressions of local codimension-1 bifurcations for a fully connected, additive, discrete-time recurrent neural network (RNN), where we regard the external inputs as bifurcation...

Platform Portable Anthropomorphic Grasping with the Bielefeld 20-DOF Shadow and 9-DOF TUM Hand (2008)

Frank Röthling, Robert Haschke, Jochen J. Steil, Helge Ritter

Abstract — We present a strategy for grasping of real world objects with two anthropomorphic hands, the three-fingered 9-DOF hydraulic TUM and the very dextrous 20-DOF pneumatic Bielefeld Shadow...

The Cyborg Astrobiologist: Porting from a wearable computer to the Astrobiology Phone-cam (2007)

Bartolo, Alexandra, McGuire, Patrick C., Camilleri, Kenneth P., Spiteri, Christopher, Borg, Jonathan C., Farrugia, Philip J., ...

We have used a simple camera phone to significantly improve an `exploration system' for astrobiology and geology. This camera phone will make it much easier to develop and test computer-vision...

SOM-based experience representation for Dextrous Grasping (2007)

Steffen, Jan Frederik, Haschke, Robert, Ritter, Helge

We present an approach to dextrous robot grasping which combines a purely tactile-driven algorithm with an implicit representation of grasp experience to yield an algorithm which can handle...

Dynamic Path Planning for a 7-DOF Robot Arm (2006)

Klanke, Stefan, Lebedev, Dimitry, Haschke, Robert, Steil, Jochen, Ritter, Helge

We present an on-line, robust, and efficient path planner for the redundant Mitsubishi PA-10 arm with 7 degrees of freedom (DOF) in non-stationary environments. Because of the specific kinematic...

Field geology with a wearable computer: 1st results of the Cyborg Astrobiologist System (2005)

McGuire, Patrick C., Gomez-Elvira, Javier, Rodriguez-Manfredi, Jose Antonio, Sebastian-Martinez, Eduardo, Ormo, Jens, Diaz-Martinez, Enrique, ...

We present results from the first geological field tests of the `Cyborg Astrobiologist', which is a wearable computer and video camcorder system that we are using to test and train a computer-vision...

The Cyborg Astrobiologist: Scouting Red Beds for Uncommon Features with Geological Significance (2005)

McGuire, Patrick C., Diaz-Martinez, Enrique, Ormo, Jens, Gomez-Elvira, Javier, Rodriguez-Manfredi, Jose A., Sebastian-Martinez, Eduardo, ...

The `Cyborg Astrobiologist' (CA) has undergone a second geological field trial, at a red sandstone site in northern Guadalajara, Spain, near Riba de Santiuste. The Cyborg Astrobiologist is a wearable...

Field Geology with a Wearable Computer: First Results of the Cyborg Astrobiologist System (2004)

McGuire, Patrick C., Gomez-Elvira, Javier, Rodriguez-Manfredi, Jose Antonio, Sebastian-Martinez, Eduardo, Ormo, Jens, Diaz-Martinez, Enrique, ...

We present results from the first geological field tests of the `Cyborg Astrobiologist', which is a wearable computer and video camcorder system that we are using to test and train a computer-vision...

Bifurcations in discrete-time neural networks : controlling complex network behaviour with inputs (2003)

Haschke, Robert

The goal of this thesis is to contribute to the understanding of the emergence of complex dynamical behaviour in small recurrent neural networks, which already exhibit a rich repertoire of complex...

Threshold Disorder as a Source of Diverse and Complex Behavior in Random Nets (2002)

McGuire, Patrick C., Bohr, Henrik, Clark, John W., Haschke, Robert, Pershing, Chris, Rafelski, Johann

We study the diversity of complex spatio-temporal patterns in the behavior of random synchronous asymmetric neural networks (RSANNs). Special attention is given to the impact of disordered threshold...
