“…Moreover, the cost of this robot was only about 175TL (~ $29.7). This finding is supported by the fact that Yang et al (2019) emphasized the low cost of Arduino. The development of such a robot by the corporation has resulted in a cost advantage of approximately 8 times the purchase from its foreign counterparts.…”

The aim of this study is to develop the university's own robotics training set, which; can be used in electronic and robotic coding education, is easy to program, is circuit protected, can be coded by written or block-based, is easy to see module connections, has no licensing and copyright problems, can reduce the usage and also outflow of public resources. In this development study, we focused on; how the robot can design, how much it will cost and what applications can be done. In this study, based on the Waterfall Model, which is one of the System / Software Project Management Models, a development card named Ardunio was used and an educational robot prototype consisting of 11 modules was produced with Arduino support. With this robot called ARUbot, a totally of 2047 different usage can be achieved by using the modules on it with various combinations. Also, ARUbot can perform many other functions such as line tracking, avoiding obstacles, measuring temperature and humidity, measuring light status, controlling with bluetooth, writing text on the screen. Moreover, thanks to the fact that such a robot is manufactured by the university, it has been found that its cost is about 8 times lower than its peers. Considering the findings put forward by the policy makers and educational institutions of Turkey within the scope of this study, it can be said that the flow of public resources abroad can be reduced with robotic coding training sets originating from abroad.

“…NDIR sensor response time (from 10% to 90%) was approximately of 2.8 seconds [13] and require of temperature compensation to avoid drift and accuracy loss [17]. Comparatively, the MQ-4 sensor is durable without loss of accuracy or reproducibility, even after ten months of use [11].…”

“…The calibration of the MQ-4 sensor was made from 0 to 120 ppm, showing that the methane sensor is very sensitive in this range [10]. Humidity influences the sensitivity of the sensor, and when drying the sample, the upper limit of the MQ-4 range was improved at least ten times [11].…”

Design of a Methane Monitoring System for Landfill and Duct Emissions

Methane is released from waste disposal areas as a result from anaerobic decay of food. Methane causes more greenhouse effects than carbon dioxide so a methane monitoring system is required to warn its release from gas emitting environments. The low explosive limit of methane is 5% in ambient air, so gas leakage is dangerous and can produce explosions. An entire head monitoring system was built around a MQ-4 methane gas sensor as it is cheap and reliable. The design proves to be flexible enough as it can measure CH 4 emissions in ducts, CH 4 in landfills at different depths and even in cattle barns. The measuring system head consists of a suction pump, solenoids, and a methane sensor. Measurements are taken 13 seconds after methane gas sucking. A timing of 100 seconds is required for purging the chamber before the second solenoid is turned-on. Devices temperature during operation was sampled with a thermal Flir-One camera and solenoid coil temperature was of 24.9˚C after a continuous operation of 30 seconds. As hoses for emission sampling become larger time for sampling increases as well as energy consumption.

“…Thus, an optimized OLR and HRT should be applied to achieve the expected specific methane yield. Possible solutions could be improving anaerobic digester configurations such as using membrane reactors or upflow anaerobic sludge blanket reactors to decouple the OLR and HRT [37,119] and on-line control of anaerobic digester operation [124]. These have not been applied for digesting algal biomass.…”

Microalgae are a promising feedstock for bioenergy due to higher productivity, flexible growing conditions, and high lipid/polysaccharide content compared to terrestrial biomass. Microalgae can be converted to biogas through anaerobic digestion (AD). AD is a mature technology with a high energy return on energy invested. Microalgae AD can bypass energy intensive dewatering operations that are associated with liquid fuel production from algae. A techno-economic assessment of the commercial feasibility of algae-based biogas production was conducted using Cyanothece BG0011 biomass as an example. BG0011 is a naturally occurring, saline cyanobacterium isolated from Florida Keys. It fixes atmospheric nitrogen and produces exopolysaccharide (EPS). Maximum cell density and EPS concentration of 2.7 and 2.1 g afdw 1 /L (for total algae biomass concentration of 4.8 g afdw/L) were obtained by air sparging. For an areal cell and EPS productivity of 12.4 and 9.6 g afdw/m2/day, respectively, the biomethane production cost was 14.8 $/MMBtu using covered anaerobic lagoon and high-pressure water scrubbing for biogas purification. Electricity production from biogas costs 13 cents/kwh. If areal productivity was increased by 33% from the same system, by sparging air enriched with 1% CO2, then biomethane cost was reduced to 12.16 $/MMBtu and electricity cost to 11 cents/kwh.
