Evaluation

Problem – product variation and palletizing. Products could be 6 or 18 packs. Each pack could be wrapped with any color package with logo or marketing material. So the goal was to illuminate the 6-18 pack so the robot could pick. IR was used to reduce the color issue as color could cause low contrast. It was important to test with the lights pointing at different angles. We found that low angle lighting provided the best results and two lights were used to achieve the desired illumination level.
