Editor's notes
Unverified (free text): US list price (store.trossenrobotics.com not fetched). Reach: manufacturer docs say 0.769 m; Génération Robots says 700 mm — docs value used. Repeatability 1 mm is from the reseller page only (docs give none). Docs list only a C++ API (trossen_arm::TrossenArmDriver) and Ethernet; ROS 2/LeRobot (Python) support from reseller page. Gripper: 40 mm max finger displacement, 100 N max grip force; 24 V nominal, 15 A peak. links.product URL from search listing (trossenrobotics.com blocks fetching). mounting 'table' is an assumption for a desktop research arm; no page states mounting options.
