TX SCARA

TX SCARA is a stocking robot built by the Tokyo company Telexistence for one narrowly defined job: filling the beverage coolers of Japanese convenience stores from the cold back room. It went into its first store — the FamilyMart branch inside Japan's Ministry of Economy, Trade and Industry in Kasumigaseki — on 2 November 2021, and in August 2022 FamilyMart committed to installing it in 300 shops. The arm is a SCARA design with the joint layout and link lengths chosen for the geometry of a cooler rather than for general use. It travels on a horizontal rail past the shelves, picks cans and PET bottles up to two litres and pushes them into place, working around the clock at up to roughly a thousand restocking operations a day. Telexistence's own perception software, called Gordon, scans the shelf, decides what is missing, works out where to grip each item and plans the path. Crucially, the whole thing is designed to be dropped into shops as they are, without rebuilding the back room. The honest part of the design is the admission that it will fail. When Gordon cannot complete a pick, the robot switches to Telexistence Mode and a remote operator takes over the arm over the internet — the teleoperation heritage the company is named after. That also changes the labour argument: instead of staff spending hours in a refrigerated room, one operator anywhere can rescue many stores. Telexistence has since moved on to a successor, TX Ghost, piloted in Tokyo 7-Eleven stores from September 2025. The manufacturer publishes throughput, product compatibility and deployment counts, but not the mechanical data — reach, payload, cycle time, weight — that a specification sheet would normally carry.
