literature review for automatic pneumatic bumper

Abstract

The aim is to design and develop a control system based an intelligent electronically controlled automotive bumper activation system is called Automatic Pneumatic Bumper . This system is consists of IR transmitter and Receiver circuit, Control Unit, Pneumatic bumper system.The IR sensor is used to detect the obstacle. There is any obstacle closer to the vehicle (with in 4 feet), the control signal is given to the bumper activation system.The pneumatic bumper system is used to produc ....etc

Abstract

In paper the fundamental question about optimal interaction between the controlling stimuli generated by the active (powered) and the passive (unpowered) drives of the robotic systems have been studied. A mathematical statement of the problem has been proposed that is suitable to study this question for the semi-passively actuated n-degree-of-freedom robotic systems. The problem is formulated as an optimal control problem for n-degree-of-freedom mechanical system models a semi-passively actuated robot. We take into account the inter ....etc

Electroactive Polymer (EAP) Actuators


Electroactive Polymer Technology

Electroactive polymers (EAP) are promising as actuators in intelligent material
systems, where large deformations are required. Electromagnetic, piezoelectric
or shape memory alloy actuators are either too heavy, too complex or too slow
for such applications. EAP however are relatively lightweight, rather simple and
fast enough.
In particular, dielectric electroactive polymers were shown to have good ove ....etc

Chapati (alternatively chapatti, chappati, chapathi, or chappathi) is an unleavened flatbread (also known as roti/rotli/rotta) from the Indian Subcontinent; and popular staple in India, Nepal, Bangladesh, Pakistan, and Sri Lanka. It is a common staple in South Asia as well as amongst South Asian expatriates throughout the world. Chapatis were also introduced to other parts of the world by South Asian immigrants, particularly by Indian merchants to Central Asia, Southeast Asia, East Africa and the Caribbean islands.

An actuator is a component of machines that is responsible for moving or controlling a mechanism or system.

An actuator requires a control signal and source of energy. The control signal is relatively low energy and may be electric voltage or current, pneumatic or hydraulic pressure, or even human power. The supplied main energy source may be electric current, hydraulic fluid pressure, or pneumatic pressure. When the control signal is received, the actuator responds by converting the energy into mechanical motion.

An actuator is the mecha ....etc

Hydraulic actuators: cylinders



Properties:

.The cylinders have to be good quality steel with close tolerances.
There have to be good sealing both at the piston rod and at the cylinder.

.With time dirt may come in and damage the surfaces. This has to be possibly reduced.
In this case, the leakage will increase all the time.

Calculation of cylinders

1 Stick-slip
2 Transition
3 Normal behaviour

Hydraulic cylinders should be possibly operated in the 3rd region for ....etc
