Abstract
  • This study aims to explore whether a robotic cookstove feeder can sufficiently reduce variability between tests of a cookstove, produces statistically similar firepower and measured emissions rates, and reduce tester interaction time during standard cookstove testing as compared to a trained human operator. A series of modified ISO/FDIS 19867-1 testing included four unique configurations, two firepowers per configuration, and five replicates per firepower. These tests were then compared to an equivalent set of tests performed by two human operators under identical conditions. The data showed that, overall, the robot cookstove feeder was as consistent as the results from the human operators. A matched pair t-test at a 90% confidence interval revealed no statistical difference in firepower or PM2.5 emissions rates. However, the human and robot’s CO2 emissions rates were very similar, differing by 6.2% (SD = 6.4%) and 4.2% (SD = 6.2%) on average for the high and medium testing power respectively. The human and robot’s CO emissions rates differed more, with the average percent difference being 9.8% (SD = 25.4%) for the high power and 21.7% (SD = 19.5%) for the medium power. A comparison of the tester interaction time showed that the robot on average saved the operator time, although not to a significant degree. The results indicate that the robot is capable of performing consistent, repeatable cookstove testing. The robot opens up many possibilities in creating more effective cookstove testing and allows operators to perform cookstove testing in a more consistent, repeatable, and automated manner.
