The necessity of the soft gripping devices is increasing day-by-day in medical robotics especially when safe, gentle motions and soft touch are necessary. In this paper, a novel asymmetric bellow flexible pneumatic actuator (AFPA) has been designed and fabricated to construct a miniaturised soft gripper that could be used to grip small objects. The model of AFPA is designed using solid works and its bending motion is simulated in Abaqus software for optimisation and compared with experimental results. The actuator is fabricated using compression molding process that includes micromachining of the molds. Experiments conducted show the bending characteristics of the actuator at different pressures. The actuator shows excellent bending performance and the eccentricity in its design supports increased bending or curling motion up to a certain extent compared to normal bellows without eccentricity. The effects of profile shape and eccentricity on the actuator performance are analysed and the results are presented.

These days mishaps may happen because of different reasons; the principal reason is brake disappointment and is caused because of poor upkeep just as item deformity. So as to safe watchman the important human life from these mishaps; there is a requirement for observing of slowing mechanism in cars. Vehicle security is the evasion of car crashes or the minimization of hurtful impacts of mishaps, specifically, identified with human life and wellbeing. Uncommon wellbeing highlights have been incorporated with vehicles inhabitants just, and some for the security of others. In this present research work a brake disappointment pointer circuit that continually screens the state of the brake and gives a broad media sign to rider has been created. Flex sensor is utilized in this proposed framework to change over power connected at the uncommon wheel in to voltage corresponding to the power connected at the break cushion. Mishap is a lamentable occurrence that happens out of the blue and ordinarily bringing about harm or damage. Mishap controller utilizing ARDUINO UNO is a technique which use flex sensors to send sign to marker that serves to 0prevent odds of mishap. The proposed framework incorporates two sorts of driving modes, programmed and manual. In programmed mode, sensors will be dynamic, contingent upon which sensor has detected the snags it will play out the relating assignment of going ahead, decreasing velocity and applying brakes. In manual mode, sensors will be inactive, steering and braking system will be under the control of driver.
