Abstract

In this paper a new simulator for cellular neural networks (CNN) called PSIMCNN is presented. It has been studied for a parallel general-purpose computing architecture based on transputers. The Gauss-Jacobi waveform relaxation (WR) algorithm has been adopted. It has been analytically proved that the WR algorithm is convergent for the most common CNN models. Implementation issues have been described and some experimental results comprising classical CNN and Chua circuits CNN simulations have been presented. Parallelism and performances have been investigated. Moreover, a comparison with the CNN-HAC simulator is reported. Key words: Cellular neural networks, simulators, non-linear circuits, transputer, parallel processing.

Abstract

We propose Radibot, a simple and cheap robotic arm for remote inspection, which interacts with the radwaste environment by means of a scintillation gamma detector and a video camera representing its light (< 1 kg) payload. It moves vertically thanks to a crane, while the other three degrees of freedom are obtained by means of revolute joints. A dedicated algorithm allows to automatically choose the best kinematics in order to reach a graphically selected position, while still allowing to fully drive the arm by means of a standard videogame joypad.

23. A walking assistant using brakes and low cost sensors

Author

Abstract

Smart Walkers are a category of robotic assistive devices particularly useful for the elderly. These systems help the users in locomotion and with respect to the classical walkers, reduce the risk of fall. This work presents a new system that has been developed using low-cost time of flight laser sensors in place of the more expensive laser scanners. Control of direction is performed by guiding the user by mean of brakes on the rear wheels. Other sensors include an inertial measurement unit with magnetometer and an interface with an external absolute localization system. Preliminary trials have been performed on a graphical and physical simulator implemented in the V-Rep framework.

Abstract

Behaviour based navigation frameworks present the need of mechanisms for behaviour coordination. Algorithms inspired by processing principles of the human brain can provide effective solutions to the coordination problem. Here we present the use of the dynamic neural field, a recurrent neural network, as behaviour coordination layer in robotics navigation algorithms. We test the control loop with the humanoid robot NAO in different contexts. Results show that the use of the dynamic neural field allows the generation of context-dependent effective behaviours.
