DEVELOPMENT WITHOUT PUMPING VACUUM PUMP GRIPPER DEVICE

Vacuum Gripper- an Important Material Handling Tool

Varieties of robotic grippers are developed with high flexibility and multi-functional approaches. In this paper, the study is an innovative approach of a gripper for handling variable size, shape and weight of unpacked food products i.e. ‘Vacuum Gripper of Robots’ which is working on Bernoulli Principle for generating a high-speed flow between the gripper plate and product surface thereby crea...

Vacuum Gauge to Vacuum Pump Valve

Machine Theory Theoretical model of the grasp with vacuum gripper

Vacuum grippers are often notably diffused for grasping and moving very large and heavy objects. The absence of theoretical models able to foresee the behavior of the suction cup notably limits the applications and development of vacuum grippers. In this work, a study of grasping with a vacuum gripper has been carried out. A mathematical model is proposed for determining the forces of contact b...

Vacuum defects without a vacuum

Topological defects can arise in symmetry breaking models where the scalar field potential V (φ) has no minima and is a monotonically decreasing function of |φ|. The properties of such vacuumless defects are quite different from those of the “usual” strings and monopoles. In some models such defects can serve as seeds for structure formation, or produce an appreciable density of miniblack holes...

Whole blood pumping with a microthrottle pump.

We have previously reported that microthrottle pumps (MTPs) display the capacity to pump solid phase suspensions such as polystyrene beads which prove challenging to most microfluidic pumps. In this paper we report employing a linear microthrottle pump (LMTP) to pump whole, undiluted, anticoagulated, human venous blood at 200 μl min(-1) with minimal erythrocyte lysis and no observed pump blocka...
