Conventionally, wireless-controlled robots use RF circuits, which have the drawbacks of limited working range, limited frequency range and limited control. Use of a mobile phone for robotic control can overcome these limitations. It provides the advantages of robust control, working range as large as the coverage area of the service provider, no interference with other controllers and up to twe...

OBJECTIVES To describe a novel technique using the image guidance system for transoral robotic surgery of the pharyngeal and parapharyngeal spaces. STUDY DESIGN Case series presentation. METHODS Three cases of oropharyngeal and pharyngeal space lesions are reviewed for presentation, workup, and original management. RESULTS Final pathology of a vascular malformation, an acinic cell adenoca...

in this research, first, kinematic and dynamic equations of a 4-dof 3-link robotic finger are derived using denavit-hartenberg convention and lagrange’s formulation. to model the muscles, several springs and dampers are placed between the finger links. then, two advanced controllers, namely adaptive-robust and adaptive-neural, which can control the robotic finger in presence of parametric uncer...

normal 0 false false false en-us x-none ar-sa background: robotic needle insertion in biological tissues has been known as one the most applicable procedures in sampling, robotic injection and different medical therapies and operations. objective: in this paper, we would like to investigate the effects of angular velocity in soft tissue insertion procedure by considering force-displacement diag...

Compared to robotic injection of suspended cells (e.g., embryos and oocytes), fewer attempts were made to automate the injection of adherent cells (e.g., cancer cells and cardiomyocytes) due to their smaller size, highly irregular morphology, small thickness (a few micrometers thick), and large variations in thickness across cells. This paper presents a robotic system for automated microinjecti...

The retromolar trigone is a challenging transoral surgical site due to the difficulty of visualization. Our aim is to report a new technique of transoral robotic resection of retromolar trigone tumours. We present three patients with retromolar trigone tumours with pathological diagnosis of squamous cell carcinoma who underwent successful transoral robotic resection. Robotic retromolar trigone ...

Robotic surgery is gaining acceptance in the management of diverse urological disorders. Any minimally invasive procedure carries a risk of open conversion either for complications or unexpected intraoperative findings, but the additional dexterity of robotic instrumentation may allow even complex situations to be managed laparoscopically. We report the case of an upper tract transitional cell ...

Adrenal surgery is undergoing continuous evolution and minimally invasive surgery is increasingly being used for the surgical management of adrenal masses. With robotic-assisted surgery being a widely accepted surgical treatment for many urological conditions such as prostate carcinoma and renal cell carcinoma, the use of the robot has been expanded to include robotic-assisted adrenalectomy, of...

although construction has been known as a highly complex application field for autonomous robotic systems, recent advances in this field offer great hope for using robotic capabilities to develop automated construction. today, space research agencies seek to build infrastructures without human intervention, and construction companies look to robots with the potential to improve construction qua...
