In the area of Bio robotics, intense research work is going on in plant intelligence. Any living cell continuously receives information from the environment. The plant electrical signal is the reaction of plants to the stimulation due to various environmental conditions. Action potentials are responsible for signaling between plant cells because they can be induced and transmitted rapidly within the...
This paper presents the analysis of grasp stability for a bio-mimetic robot hand by using polygon segmentation algorithm. The presented hand has four independency moving fingers, which are driven by four-coupled link mechanism with two linear actuators. The robot hand was designed considering the dexterity and the compact size suited for various objects in daily life. Tactile sensors are mounted on...
Vibration becomes a major control issue as industrial robots get lighter and slimmer. Proportional- Integral-Derivative (PID) control is simple and easy to regulate the motion of robots. If gains of PID can be tuned precisely for the given purpose, it will be more beneficial than heavy and complicated control algorithm. The paper introduces the feasibility of PID tip position control to suppress oscillation...
This paper describes grasp stability for a multi-fingered robot hand, called the KIST hand. The robot hand has controlled by four under-actuated fingers with totally nine DOFs, which are controlled by two linear actuators and linkage knuckles. This mechanism is able to generate high power compare to common robot hands that use rotary actuators. The robot hand has four tactile sensors which are attached...
