B-spline Makes Robot Arms Faster and Smoother
Haoyu_Xiong_ · x · 2026-07-15
This post introduces a new robotic manipulation method: B-spline Policy (BSP).
The author notes that while past manipulation evaluations often focused on success rate, speed is equally important. Instead of predicting discrete, fixed-frequency action chunks like traditional methods, BSP parameterizes actions as continuous B-spline curves.
They claim that this representation, combined with the system design, enables low-cost robotic arms to achieve faster and smoother manipulation. The post also emphasizes:
- The project is co-led by multiple researchers;
- The included video shows the robot moving significantly faster than the baseline;
- The video footage is recorded in real-time.
