B-spline Makes Robot Arms Faster and Smoother

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:
