“…2) is a pedalling device that may be used as an interface between a human worker and any rotary machine for utilization of human muscle power in efficient manner. It was designed by Tiwari et al(2011) and optimized to operate at 50 rev/min for sustainable work. It consists of an enclosed flywheel of diameter 520 mm and weight of 23 kg.…”

“…Overall dimension of the dynapod is 1175 x 503 x 1100 mm. The total weight of dynapod is 68 kg.For Indian agricultural workers, the muscular power output in pedalling mode sustained for long duration is 60 W. At this power output, the optimum pedalling rate, at which the physiological and psychophysical responses were minimum, is 50 rev/min (Tiwari et al, 2011, Potdar et al, 2011.…”

An ergonomic evaluation cleaner-cum-grader with original cycle mechanism and ICAR-CIAE developed dynapod was conducted. The study was conducted with 15 male subjects aged between 20-40 years, mean stature of 1640 ±40 mm and mean weight of 54 ±5 kg. The maximum aerobic capacities of the subjects were determined using sub-maximal exercise protocol. The mean working heart rate of the subjects in operation of machine with original cycle mechanism was 157 beats min-1 as against 125 beats min-1 with dynapod. The work pulse (ΔHR) of 57 beats min-1 and 31 beats min-1 was observed for pedaling with cycle mechanism and dynapod, respectively. The output capacity of machine increased by 41 kg h-1 with use of dynapod compared to pedaling with cycle mechanism. Using dynapod in operation of cleaner-cum-grader resulted in drudgery reduction by 51.6 % as compared to the original cycle mechanism.

“…It is observed that most of the researchers consider Oxygen consumption is one of the indications of the energy requirement of the human body at work [12] . As the oxygen requirements are increased with the increases in the level of physical activity, the cardiovascular system speeds up its function thus increasing heart/ respiratory / pulse rate and blood pressure [12]. Thus as a measure of the energy cost of work, pulse rate is use.…”

Designing for the oppressed part of the generalized public is one of the fundamental prerequisites for comprehensive design in a developing nation like India. With a spurt being developing inside a nation, the financial distance between those who are well off and the wealthy not are expanding and this divergence is making social agitation in the nation. Tricycles rickshaw is a small-scale ordinary means principally utilized for transportation. Numerous deficiencies were reported in the existing type of tricycle. For optimization of those deficiencies, three different models of cycle rickshaw were utilized, and the input parameter that regulates the consumption of human energy and performance was identified. Regression Analysis (RA) and Artificial Neural Networks (ANN) were utilized for analysis of the experimental data. Both RA and ANN modeling were assessed statistically with the aid of a software tool. RA of the experimental data reveals that input variable load is a most prominent parameter to be focused on tor achieving the objective of expending minimum human energy by a rickshaw puller whereas ANN studies acknowledged the assistance of multiple factors in individual energy. However, load is a most prominent parameter for minimization of individual energy as Outcome. Optimization of input variables using Min-Max principle for various regression models yielded the optimal solution at crank length 167 mm and wheel diameter 675mm for human energy for all linear regression models.

“…After that, the subject was asked to start pedalling work on the pedal operated maize dehusker sheller until they are tired. The pedalling speed was maintained at 50 rpm as it is the optimum pedalling rate for an Indian agricultural worker for daylong pedalling work [14]. The recorded data was transferred to computer for further analysis.…”

The pedal-operated maize dehuskar-sheller was ergonomically evaluated with ten male agricultural operators to assess the physiological costs of operation. The Heart Rate, Oxygen Consumption Rate and energy expenditure rate were used for assessment of physiological cost for the operation of the pedal operated maize dehuskar sheller. The Heart Rate and Oxygen Consumption Rate were measured with Computerized Ambulatory Metabolic Measurement System K4b 2. The energy expenditure rate was calculated based on the Oxygen Consumption Rate during the operation. The mean working heart rate, mean working Oxygen Consumption Rate and mean working energy expenditure rate of all subjects during the operation of maize dehusker sheller were found to be 139 (± 22.01) beats/min, 1.40 (± 0.20) l/min and 6.83 (±1.07) kcal/min, respectively. Based on energy expenditure rate, the operation of pedal operated maize dehusker sheller was found under 'Heavy' work category.
