robotindex Dobot X-Trainer
A dual-arm teleoperation kit from Dobot for collecting robot-learning data. An operator drives two Dobot Nova 2 arms through two master hands while the system records trajectories and camera views in AI-ready formats. Each arm has 625 mm of reach and ±0.05 mm repeatability, with wrist and global cameras and an open API. Dobot opened pre-orders in April 2024 and does not publish a price; resellers list it at roughly £18,700 or €33,400 including VAT.

Reference Price
Dobot does not publish a price. Scan UK lists the kit with two Nova 2 arms at £18,687.98 including VAT and in stock; Funduino Shop lists €33,390 including VAT with a 21-business-day delivery time; Rapid Online shows price on application. Each is a single reseller figure, and they differ widely. Other listings sell the platform without the Nova arms, and a lightweight-base edition also exists; those prices were not retrieved. robotindex does not sell this product.
Insights
X-Trainer is aimed at the data bottleneck in robot learning: it records an operator's demonstrations on real arms so the data can train imitation-learning and vision-language-action policies. Dobot says it cuts training time by 70% and that a simple task such as dishwashing can be learned in about two hours; these are Dobot's own claims. Beyond the master-hand rig, Dobot's GitHub repositories add VR teleoperation (Quest 3 and PICO 4), keyboard control, and capture in HDF5 compatible with LeRobot, and a dataset repository exists on Hugging Face. The repositories are open source (BSD-3-Clause for
embodied-dobot/x-trainer, GPL-3.0 for Dobot-Arm/dobot_xtrainer), but the arms, master hands and cameras are commercial hardware, so this page carries no Open Source badge. The arms are Dobot's Nova 2, which RobotShop lists as an entry-level six-axis collaborative arm.Verified against Dobot's X-Trainer announcement (dobot-robots.com), Dobot's GitHub repositories (embodied-dobot/x-trainer, Dobot-Arm/dobot_xtrainer), How To Robot's launch article, and retailer listings (Scan UK, Rapid Online, Funduino Shop, DigiKey), as of October 2026. Flagged as uncertain: Dobot's own product pages returned errors or were blocked, so specs come from the announcement, GitHub and retailers; no official price exists and the two prices quoted are single-retailer figures in different currencies, both including VAT; the 2 kg / 3 kg payload, 1.6 m/s speed, ISO 15066 and Intel D405 details come from retail listings; the 14 DoF figure comes from Dobot's GitHub README; weight and dimensions were not found; the picture appears to show the operator-side master hand, not a Nova 2 follower arm, which could not be confirmed; and the lightweight-base and no-arms variants were not priced or compared.
