Title:

ROBOT ARM MECHANISM

Document Type and Number:

WIPO Patent Application WO/2016/084943

Kind Code:

A1

Abstract:

The purpose of the present invention is to inhibit collisions between a first coupling-segment row and a second coupling-segment row in a robot arm mechanism provided with a direct-acting extensible/retractable joint. In this robot arm mechanism provided with a direct-acting extensible/retractable joint, the direct-acting extensible/retractable joint is provided with an arm part (2), and an ejection part (29) which supports the arm part (2). The arm part (2) is provided with: a first coupling-segment row (21) formed from a plurality of first coupling segments (23); and a second coupling-segment row (20) formed from a plurality of second coupling segments (22). The second coupling-segment row (20) is dispatched forwards from the ejection part (29) in conjunction with the first coupling-segment row (21), in a state of being joined to the first coupling-segment row (21). A flexible guide rail (41) for separating the first coupling-segment row (21) and the second coupling-segment row (20), and guiding the second coupling-segment row (20) to the ejection part (29), is provided to the rear of the ejection part (29), and between the first coupling-segment row (21) and the second coupling-segment row (20).
