EXTENDED REACH MASTER SLAVE MANIPULATOR
LOW FRICTION MANIPULATOR

Master-Slave Manipulators (MSMs) are the most widely used remote handling tools in nuclear industry. Bhabha Atomic Research Centre (BARC) has developed various models of master-slave manipulators with different payloads and ranges. They are used in various hot cells in BARC and other DAE units. Extended Reach Master Slave Manipulator (ERM) is a recent addition to this list. ERM has low friction compared to other manipulators

Features

ERM has 6 independently controlled joints (6 DOF) for arbitrary positioning and orienting the object. Power is transmitted from the master to the slave through stainless steel wire ropes, stainless steel tapes and a parallelogram mechanism. To reduce the operator’s effort, the manipulator joints are mechanically balanced in all configurations. The first 3 axes of the manipulator are provided with electrical indexing motions. 

Advantages

It increases the range of slave arm, improves operator ergonomics, provides better viewing, and helps to orient the slave for insertion of the manipulator into the hot cell.

Specifications

Extended Reach Master Slave Manipulator has 9 kg payload and a reach of 3.4 m.

Application

Remote handling of radioactive materials in hot cells
