Academic automation prototype
Automated Shopping / Retail Automation Prototype
A camera-guided retail automation prototype that recognised fruit, estimated a grasp point, and connected perception to robotic-arm handling.

01
A simple retail task with a full automation chain
The prototype focused on a narrow physical task: identify fruit on a conveyor or shelf and give a robotic arm enough information to handle it. That scope was small enough to demonstrate, but it still required perception, localisation, and action to work together.
The camera provided the scene, YOLO identified the product, and a grasp-point step translated the detection into a location suitable for manipulation.
02
Recognition was not the final output
A bounding box was useful for checking that the model saw the correct item. The automation path needed more: a stable target point, a coordinate conversion, and a decision about when the arm should move.
I worked on the computer-vision side of that chain, including fruit recognition and grasp-point detection. The output had to be predictable enough for the next component to consume.
03
Closing the camera-to-arm loop
The prototype connected the camera result to robotic-arm behavior so perception could drive an action rather than remain a standalone demo. That required checking that the scene and target were still valid when the command was issued.
Even in a controlled academic setup, lighting, object overlap, position, and movement affected the result. The system needed clear failure behavior when a useful grasp point was not available.
04
Prototype scope and limits
This was an academic automation prototype, not a deployed retail system. It did not establish production throughput, broad product coverage, or commercial reliability.
Its value was the complete chain from image to physical action and the engineering questions that appeared between those two points.
Outcomes
- 01YOLO-based fruit recognition in a controlled conveyor or shelf scene.
- 02Grasp-point output suitable for a robotic-arm manipulation experiment.
- 03A closed camera-to-action prototype rather than an isolated detection demo.
What I learned
- 01Automation needs an action-ready output, not only a visually correct detection.
- 02Failure handling matters whenever perception controls physical movement.
- 03Narrow prototypes are useful when their limits are stated honestly.
