As end-to-end learning-based approaches for fast, vision-based quadrotor flight become more prevalent, we study the capabilities of a vision transformer (ViT) architecture that maps depth images to velocity commands both in simulation and real-world. We find that when combined with LSTM layers, a ViT outperforms other state-of-the-art architectures of choice (UNet, LSTM-only) as forward velocity increases. We also find that this model can zero-shot transfer to high-speed real-world dodging in indoor scenes.
