a Workflow of the vial positioning detection system based on DenseSSD. An action is defined as the movement of the robot arm to relocate each vial to its holder. Green and red boxes represent the predicted bounding boxes for the success and failure cases, respectively. When a failure vial positioning case is detected by DenseSSD, an alert is remotely and immediately sent to the responsible researcher. b The network architectures of DenseSSD, which largely consists of mainstream structure and pyramidal feature cascading structure. The conv 3 × 3 and conv 1×1 refer to convolution layers with filter sizes 3 × 3 and 1 × 1, respectively. The avgpool layer means an average pooling layer with its size 2×2. Each transition layer is composed of conv 1×1 and avgpool, while each reduction layer has the reversed order composition of avgpool and conv 1×1. More detailed layer information can be found in Supplementary Table 1.
