As part of a social investment partnership with Rotary International, Jendamark India and suppliers recently sponsored 38 Odin Education tablets to 8th grade students at the SAMPARC Gramin Vidya Vikas Kendra School in the village of Bhambarde in Mulshi Taluka.
SAMPARC, which stands for Social Action for Manpower Creation, is the brainchild of Shri Amitkumar Banerjee, who started this organisation of hope in 1990 for children of sex workers as well as orphans and destitute children. It works in Jendamark India’s home state of Maharashtra and in Rajasthan, West Bengal and Uttar Pradesh, offering services ranging from children’s homes to community education support programmes, industrial and vocational training centres, and schools.
SAMPARC started its second centre in Bhambarde to give poor children from nearby rural villages a chance to attend school. Recently named the best school in Mulshi Taluka, the award-winning Bhambarde Gramin Vidya Vikas Kendra now has a hostel and facilities for 281 students from the 5th to 12th grade and offers the finest computer class in the district.
Rotary Club of Pune Wisdom identified the school as the right fit for this ed-tech sponsorship. The 8th grade students were introduced to the Odin Education ecosystem and received their ed-tech tablets, which were pre-loaded with their syllabus content and related educational resources and learning platforms. As individual students engage with the device, they will also be served with content about specific subjects and activities they are interested in that don’t form part of their curriculum.
Special thanks to Jendamark India’s partners in this project: Sandesh Cargo Movers, S.P. Engineering, Sai Industries, Shree Ganesh Packers, Santech Systems, Shruti Transport, Swiftin Corporation LLP, Access Industrial Sol, Sigma Tools & Machine Solutions, Swara Industries, and S.B.

The Government of India has introduced a new set of rules under the AIS 156 banner, designed to regulate electric vehicle (EV) assembly, given the complexities and incomplete technical expertise of this burgeoning industry.
Electric vehicles have been holding their own since entering the global market, as they offer significantly lower running costs and less environmental pollution than internal combustion engine (ICE) vehicles. An EV consists of many electronic parts and a large cluster of wires connecting them to the battery and motor, which contributes more than 50% of the vehicle’s total weight and price.
Because battery packs tend to have more safety and operational issues than other components, the new AIS 156 regulations call for a data-driven assembly process and more control over the manufacturing of EVs.
Standard requirements
The AIS 156 standards require manufacturers to store cell grade and quality data, like Open Circuit Voltage (OCV) and Internal Resistance (IR), as well as the cell manufacturer data, against the serial number for each cell prior to assembly.
After assembly, the total battery pack OCV and IR must also be recorded, as it is mandatory to put the same grade of cells in a single battery pack. This is essential for maintaining the quality and safety of the EV.
According to Jendamark India director Himansha Jadhav, Jendamark has put automation solutions in place to help manufacturers measure these values and place cells as per their grading.
“ODIN Workstation records the data with which it controls the process to ensure that the graded assembly of battery packs is followed.”
“Another parameter is Ingress Protection (IP X7) standards for water and dust-resistant packaging of battery packs. Manufacturers will have to perform leak testing for which we provide automation, process security, and data capturing of leak and pressure values,” explains Jadhav.
In addition, AIS 156 also lists testing requirements for battery management systems, thermal management and charge-discharge of battery packs.
“For this, we have successfully integrated with the testing machines, and store data to decide whether the battery pack is built as per requirements. All this data can be seen against the serial number of each battery pack.”
Supporting complex assembly
“In India, up to 75% of workers are contract based, which results in an untrained and inexperienced workforce. Add to that the revolutionary and complicated nature of the EV product, and there is a clear need for extensive operator training and guidance,” explains Jadhav.
A process security system that will ensure product quality and protect the operator from harm is essential, he adds.
“In this era of Industry 4.0, manufacturers need data traceability, providing analytics for each process, and to be able to manage different variants on a production line.
“Jendamark’s homegrown software solution includes Odin Workstation, which handles all these complexities and ensures right-time assembly every time.”
Step-by-step operator guidance on an interactive touch screen allows workers to easily follow the set process for assembling each type of battery or variant, while enabling companies to spend less time on training.
“We’ve seen companies putting a lot of time, money and sweat into developing products and building prototypes necessary for the certification to launch the product, but that doesn’t always translate into the production being done with the same amount of care, comfort and expertise,” cautions Jadhav.
“We know there is a need to meet production volumes to fulfil market demand, but an incorrectly assembled product can be disastrous for any company, leading to product recall campaigns.”
Because ODIN Workstation is integrated with on-field devices like cameras, tightening tools, sensors and leak test machines, it will not allow the operator to skips steps. This ensures that products are correctly manufactured every time.
Looking ahead
Jadhav expects data-driven process control to become a required norm in the near future.
“Manufacturers are already upgrading the manufacturing process to include a mix of automation and process security for their assembly line. This ensures optimum use of investments and 100% right production output.
“Jendamark, having developed and deployed such solutions, is already ahead and ready to deploy more such solutions. We have also dedicated substantial resources and already offer our customers new technology solutions such as AI-based vision systems, collaborative robots, and IOT sensors in proof-of-concept stage.”
