Key facts
- Specs on the product page (fetched 2026-10-17): payload 1.5 kg, reach 700 mm, span 1400 mm, 6 DoF, repeatability 1 mm, weight 4 kg. Driver documentation (docs.trossenrobotics.com, fetched 2026-10-17): reach 0.769 m, 24 V nominal, 15 A peak, Ethernet, finger displacement 0.04 m, max grip force 100 N.
- Joint limits from the docs: J0 +-180 deg, J1 0-180, J2 0-135, J3 and J4 +-90, J5 +-180; joint speed 360 deg/s (J0-J2) and 540 deg/s (J3-J5); nominal effort 27 N.m (J0-J2) and 7 N.m (J3-J5). max_speed_ms/kmh left null because no tool speed is published.
- Weight conflict: product page and docs say 4 kg, the store listing says 6 kg. 4 kg used (manufacturer page and docs).
- Previous generation: the Trossen docs (specifications/arms.html, https://docs.trossenrobotics.com/trossen_arm/main/specifications/arms.html) say 'The WidowX AI is the previous-generation arm. Its specifications are kept for reference.' The store shows 'Sold out' with 'The new generation product line are available now for pre-order' and a 6-8 week lead time, while the www page still shows add-to-cart and 2-3 weeks. Status is set to 'limited' because availability is contradictory; no source calls it discontinued. Newer WidowX Core (2 kg, 5.5 kg, 0.790 m), Pro (4 kg, 6 kg, 1.114 m) and Heavy (6 kg, 8 kg) are listed in the same docs; they are not catalogued here and are not stated as direct successors, so no successor_id is set.
- Not published on the fetched pages: IP rating, operating temperature, power draw, launch date (year_available left null), certifications.
- Product page also offers a TOTL Workstation compute bundle (NVIDIA RTX 5090, Intel Core Ultra 9) at USD 10,995.95; it is an accessory and not a variant.
- Image: Trossen store product render (arm with camera and gripper), on white, from the store's own product listing.
- The store listing shows 'Sold out' (6-8 week lead time) while the www page still takes orders; the prices are store list prices and the status stays 'limited' for that reason. The image is the Follower configuration (gripper and camera), not the Base arm.
