In this contribution we present a portable system which records interactions with objects of daily use automatically. The system is based on an Ultra High Frequency (UHF) Radio-Frequency IDentification (RFID) device and can be worn around the wrist. It is able to detect proximity to objects marked with an RFID tag, store collected information and transfer it wirelessly to a server. Such devices are...
Dexterous distal arm functions are crucial for execution of activities of daily living (ADLs). However, it remains difficult for patients with neurological deficits, such as stroke, to recover the lost manipulation capabilities. In this paper, a modular approach has been proposed to design a wrist-hand manipulator to be employed in the rehabilitation training of the upper limb dexterous function....
Minimally invasive robotic surgery (MIRS), compared to open surgery and traditional minimally invasive surgery, has advantages especially for patients and surgeons. In MIRS the surgeon's capabilities are extended for kinds of dexterous instruments, and surgeons could perform precise and dexterous movements which are difficult to carry out by means of rigid instruments. In this paper, the design of...
Endotracheal intubation (ETI) is a difficult technique and requires a great deal of practice to master. Research on the difference in movements between experts and novices performing the procedure has shown that experts perform movements more precisely than novices. Experts keep a fixed posture and use the upper arm muscles and wrist joints more effectively. These studies were conducted using optical...
Kinematic planning for performing manipulation tasks with an Atlas humanoid robot is presented. A hybrid analytic/numerical inverse kinematics approach is described, yielding fast solutions. The solution technique supports extensive exploration of manipulation strategies. Task-specific optimization metrics are introduced, leading to manipulation plans for three tasks: acquiring a horizontal cylinder,...
In this paper, the design of a 8 degrees-of-freedom (DOF) force reflection master manipulator for applications in minimally invasive surgery is presented. The manipulator includes three parts: arm mechanism, wrist mechanism and clamping mechanism. Arm mechanism is capable of position and force reflection in three translational motion. The wrist mechanism has a redundant DOF and can provide 3 DOF orientation...
