Plush recognition, depth camera, own servo, power boards redesigned (Patreon)

Sorry for lack of updates last months. Actually we do have updates, but most of them is far from finish. COVID19 lock-down limits our ability for meeting but we work online.

1. We developing machine vision module for Sweetie. On attached video you can see some examples of plush body and muzzle recognition. Especially for this, we created and label out plush dataset and teach neural net on it. More objects is on it's way.

2. We participated in online competition at the Russian ROS Online Meetup and won one of the prizes - Intel RealSense D435i Camera. It's special depth camera for robots, it aimed build a 3d point cloud of the area of view. For example, this may allow Sweetie to avoid obstacles. But processing of data from this camera is not an easy task.

3. We started develop own BLDC based servo. We feel that we have reached the limit of on the shelf solutions. Own servo will help us to move on in the future.

4. Completely redesigned power boards on proto3. it will be based on the new controller and periphery.
