PURPOSE Colonoscopy is one of the most effective diagnostic and therapeutic tools for colorectal diseases. We aim to propose a master-slave robotic colonoscopy that is controllable in remote site using conventional colonoscopy. MATERIALS AND METHODS The master and slave robot were developed to use conventional flexible colonoscopy. The robotic colonoscopic procedure was performed using a colo...
The term "robot" refers to a precision mechanical device that is accurately controlled by a computer using intelligent software. The term "robotic assistance" refers to the use of such a device to aid a surgeon in the optimal conduct of a procedure, particularly one requiring specified geometrical relationships. The authors have been exploring the application of robotic assistance in situations...
Laparoscopic colorectal surgery is believed to be technically and oncologically feasible. Robotic surgery is an attractive mode in performing minimally-invasive surgery once it has several advantages if compared to standard laparoscopic surgery. The aim of this paper is to report the first known case of colorectal resection surgery using the robotic assisted surgical device in Brazil. A 35-year...
The design of an ultrathin, conformal electronic device that integrates electrotactile stimulation with electromyography, temperature, and strain sensing in a single, simple platform is reported. Experiments demonstrate simultaneous use of multiple modes of operation of this type of device in the sensorimotor control of robotic systems, in the monitoring of lower back exertion and in muscle sti...
This paper describes the development of a prototype robotic endoscope for gastrointestinal diagnosis and therapy. The goal of this device is to access, in a minimally invasive fashion, the portions of the small intestine that cannot be accessed by conventional endo-scopes. This paper describes the macroscopic design and function of the device, and the results of preliminary experiments that val...
Binary robotic devices have been proposed to perform complex tasks. These systems do not require feedback and are very easy to control. Their kinematic performance approaches that of continuous devices as their degrees of freedom becomes large. To date, high DOF binary systems have not been demonstrated, largely due to actuator limitations. Recently, significant advances have been made with die...
Inherent dangers in mining operations motivate the use of robotic technology for addressing hazardous situations that prevent human access. In the context of this case study, we examine the application of a robotic tool for map verification and void profiling in abandoned limestone mines for analysis of cavity extent. To achieve this end, our device enables remote, highly accurate measurements ...
