Shinko Electric, Taiyo, and Kayaba Industry are manufacturers of machine loading robots that entered into the transfer field. The con- veyor manufacturers that entered the field include Tsubakimoto and Sanki Engineering. The “universal robot makers” offering machines for transferring include Kawasaki, which offered modifications of its Unimate for that purpose, Daido Steel, Yaskawa, Nachi Fujikoshi and Toyoda Machine.

Motoda (now Oriental Terminal Products) makes a complete line of what is described as multi-purpose versatile robots in both variable sequence and playback versions. Their major, if not exclusive, market, seems to be the materials handling area but Motoda claims that these robots can be used for welding and spray painting. Toyo Keiki has developed a series of variable sequence robots specifically dedicated to palletizing and depalletizing. The entire area of transfer robots like the area of machine loading robots is still too greatly splintered to provide a mean- ingful market share analysis.
