We present the rst stages of the developmental course of a robot using vision and a 5 degree of freedom robotic arm. During an exploratory behavior, the robot learns visuo-motor control of its mechanical arm. We show how a simple neural network architecture, combining elementary vision, a self-organized algorithm, and dynamical Neural Fields is able to learn and use proper associations between ...

We reported the optical properties of hybrid Mach-Zehnder Interferometer (MZI) designed by silicon waveguide covered with graphene material in single-atomic layer thickness. Graphene was applied to the specific area of MZI arm in certain length. The upper arm was set as the sensing region and another arm plays an important key as the reference signal. The sensor sensitivity has determined mathe...

The recent availability of modern big.LITTLE ARM chips featuring heterogeneous processor cores has enabled a practical investigation of the heterogeneous chip concept and its implications for performance and energy. The ODROID XU+E platform produced by Hardkernel integrates hardware power monitors for the individual chip clusters, GPU and Memory. In this paper we investigate the detailed energy...

The trajectory control of a pneumatically driven robot arm resembing a skeletal muscle system is studied. The arm dynamics have been shown to be hysteretic and signiicantly changing in time due to external innuences (Hesselroth et al., IEEE Systems, Man and Cybernetics, in press) thus requiring an adaptive controller. A highly adaptive feedback algorithm is suggested and shown to control accura...

This paper introduces constant-time ARM Cortex-A8 ECDH software that (1) is faster than the fastest ECDH option in the latest version of OpenSSL but (2) achieves a security level above 2 using a prime above 2. For comparison, this OpenSSL ECDH option is not constant-time and has a security level of only 2. The new speeds are achieved in a quite different way from typical prime-field ECC softwar...

This paper mainly describes the design and development of the humanoid robot arm. First, according to the requirements of tasks and anthropomorphic characteristics, the 7-DOF humanoid arm with non-offset S-R-S configuration is identified by evaluating four alternatives. The humanoid arm is accomplished with modular design, and is composed of links and modular joints. Cables between joints pass ...

Abstract This article presents Lock-V, a heterogeneous fault tolerance architecture that explores dual-core lockstep (DCLS) technique to mitigate single event upset (SEU) and common-mode failure (CMF) problems. The Lock-V was deployed in two versions, Lock-VA Lock-VM by applying design diversity processor architectures at the instruction set (ISA)-level. features an Arm Cortex-A9 with RISC-V RV...
