The requisite cabling and control processing for surgical robots can become unwieldy as dexterity is increased, due to the additional degrees of freedom. Motivated by dexterous snake-like robots for minimally invasive surgery, this paper details the development of a low-level control system that uses IEEE 1394 (FireWire), linking the computer to low-latency field-programmable gate arrays, to distribute...
We present an implementation of the Speeded Up Robust Features (SURF) on a Field Programmable Gate Array (FPGA). The SURF algorithm extracts salient points from image and computes descriptors of their surroundings that are invariant to scale, rotation and illumination changes. The interest point detection and feature descriptor extraction algorithm is often used as the first stage in autonomous robot...
This paper describes the design and construction of a low cost Autonomous Underwater Vehicle (AUV) prototype that can work as launch platform of a small UAV. The AUV can travel in a determined path to reach the launch AUV point. The AUV length is less than 2 m. The max operation depth is 20 m. It is composed of eight modules: propulsion, power, motor driver, CPU, sensor suite, camera system, communication...
