Two instances of SingleVLA (0.8B) are connected through Joint... 9 min read · [telos-robotics.hashnode.dev](https://telos-robotics.hashnode.dev/twinvla-bimanual-manipulation-from-two-single-arm-vlas-outperforming-rdt-1b-with-50-episodes?utm_source=hashnode&utm_medium=feed) [Apr 21](https://hashnode.com/posts/twinvla-bimanual-manipulation-from-two-single-arm-vlas-outperforming-rdt-1b-with-50-episodes/69e80f08f380b6cbf3d8ce40) ### [TwinVLA: 단일 팔 VLA 두 개로 양팔 조작 구현 — 50 에피소드로 RDT-1B 능가](https://telos-robotics.hashnode.dev/twinvla-vla-50-rdt-1b?utm_source=hashnode&utm_medium=feed) TL;DR TwinVLA(arXiv:2511.05275)는 두 개의 사전 훈련된 단일 팔 VLA를 조합해 양팔 조작(Bimanual Manipulation)을 구현하는 프레임워크다. 양팔 데이터로 처음부터 대규모 사전 훈련 없이, 단일 팔 데이터만으로 사전 훈련된 SingleVLA(0.8B)를 두 개 인스턴스로 구성하고 Joint Attention + Causal Mask로 양팔을 협조시킨다. 결과: RDT-1B(학습 데이터 2,400시간)을 ... 8 min read · [telos-robotics.hashnode.dev](https://telos-robotics.hashnode.dev/twinvla-vla-50-rdt-1b?utm_source=hashnode&utm_medium=feed) [Apr 21](https://hashnode.com/posts/twinvla-vla-50-rdt-1b/69e80f07f380b6cbf3d8ce3e) ### [Swerve Drive: Slip-Free Omnidirectional Platform — Complete Analysis (2/3/4-Wheel Comparison)](https://telos-robotics.hashnode.dev/swerve-drive-slip-free-omnidirectional-platform-complete-analysis-234-wheel-comparison?utm_source=hashnode&utm_medium=feed) TL;DR Swerve Drive is an omnidirectional mobile platform where each wheel independently controls both its steering angle and drive speed. It achieves slip-free omnidirectional motion with full traction — the key advantage over Mecanum/Omni wheels.
