- The author built a desk-side robotics research setup totaling €4,569.80 (excluding VAT and compute) — well under the €10,000 budget ceiling — featuring a UFACTORY xArm Lite 6, two cameras, and a 6-DoF space mouse for teleoperation.
- The UFACTORY xArm Lite 6 went from unboxing to operating in roughly 30 minutes, connects via Ethernet with a web interface, ships with a pragmatic Python SDK supporting TCP-space actuation, and includes self-collision avoidance plus configurable force-abort limits.
- The gripper is the build's weakest link: pneumatically actuated, noisy, sensorless, and forces a swap-the-fingers trade-off between grasping small or large objects, never both.
- The author's prior OpenAI setup (2017–2020, humanoid hand then tabletop) was roughly an order of magnitude more expensive and required a team of about 20; the author argues a single person at a desk can now get "surprisingly far" on real hardware.
- Compute runs on an NVIDIA DGX Spark box the author already owned, which is why GPU cost was excluded from the build total.
- The research output will be a public log of what works and what fails — explicitly not papers and explicitly not open-source code — running over the next several months.
- Vision uses a wrist-mounted camera plus a static desk-mounted camera, with the author embracing the resulting data mess (variable lighting, shifting background) as a feature rather than a bug.
Why it matters: Robotics manipulation research that once required a ~20-person team and a budget roughly 10x larger is now plausibly within reach of a single person at a desk — the author's €4,570 xArm-based build is a live test of that thesis, with the pneumatic gripper as the main weak link limiting which tasks are even possible.
