The renovation program for robots which is offered by companies such as ABB Flexible Automation and Maser Robotique is discussed. Maser's robot maintenance programs involve checking each robot every six months so that a breakdown never occurs. A renovation may include some modernization or some improvement of the robot. Maser has developed ways of obtaining a better reliability. ABB Flexible Automation is in the process of setting up an international network for robot renovation. A renovated robot is considered as an economic investment by customers because it costs half the price of a new one with the equivalent performance.
