+Simple UI to get robot info and test basic functionality. The **Robot Type** as configured in the firmware is displayed as text and animation. The checkmarks in the sections **Sensors**, **Wheel Odometry** and **LEDs** show which features are supported by the connected robot. The section **Readings** provides the most important sensor measurements. In the section **Send Commands**, users can send basic motor commands by pressing the corresponding buttons and control the front and rear LEDs with a slider.

 All models are quantized for better performance on embedded devices. Please refer to section below for a short description of the available models and benchmarking results. The [mean Average Precision (mAP)](https://kharshit.github.io/blog/2019/09/20/evaluation-metrics-for-object-detection-and-segmentation) is computed on the validation set of the [COCO Detection 2017](https://cocodataset.org/#detection-2017) dataset. Each model is run for about 1 minute; the inference time is averaged across the last 100 frames and reported in frames per second (fps). Note that models with larger input resolution might be better for smaller objects despite lower mAP.
