Holonomic robot build update
Setting up the OAK-D and RPLidar
Since the last update, I have been waiting on acrylic parts for the OAK-D camera and the OAK-D itself. The OpenCV AI Kit - Depth (OAK-D) is a spatial-AI camera with a RGB and stereo cameras with on-board mono/stereo inferencing. After a few delays, apparently due to Brexit, the camera...
