Matsushita, Mitsubishi, NEC, Oki, and Fujitsu, have developed fully A l l t h e s e u s e c a m e r a s f o r v i s u a l a u t o m a t i c s y s t e m s f o r b o n d i n g perception to position by shape or pattern and in the case of Hitachi and Mitsubishi Electric, to detect defects.

In addition, special purpose automatic assemblers provided con- siderable data for constructing assembler robots. Hitachi built for Nissan an automatic tire fitting system which uses a machine hand to detect the hub bolts, position them, and tighten them. Hitachi also developed a fully automatic system for fitting rubber belts to tape recorders from which they learned assembly principles suitable for automobile and electric appliance belt fitting.

Hitachi manufacturers an intelligent robot with a 25 step memory

Both Hitachi and Matsushita have built experimental robots to assemble electric vacuums.

The larger electronic/electrical manufacturing companies are planning to robotize 50-75% of their assembly operations by 1985. This would in- dicate that far more activity and experimentation has taken place than has

so far been publicly revealed. to me. )

(Still this forecast seems too optimistic

In March, 1981, Hitachi publicly announced a task force of 500 key technology experts to fashion and install a standardized assembly robot with both visual and tactile sensors, microcomputer control, and mobility and projected a 60% robotization of its assembly processes by 1985. In April, 1981, Matsushita announced a plan to marshall the entire staff of its technological division to develop intelligent industrial robots controlled by microprocessors and modularized (BBS) . Matsushita revealed that some BBS robots were already functioning at its plants.

The new robots were to be of three types (1) robots that position
