Please help me to interface rishabh energy meter EM 1340 with Arduino Uno. I have tried using ModbusMaster Library and SimpleModbus Library for coding in arduino. I have build RS485 to TTL converter using MAX485 IC and circuit which is given in SimpleModbus Library . I can share the code with you . My problem is that i am always getting Timeout Error . I checked on DSO the query at the converter end is not what is accepted , I mean when arduino sends query the message in form of square wave but at converter end their is loading . Please tell me ....etc

Abstract

In paper the fundamental question about optimal interaction between the controlling stimuli generated by the active (powered) and the passive (unpowered) drives of the robotic systems have been studied. A mathematical statement of the problem has been proposed that is suitable to study this question for the semi-passively actuated n-degree-of-freedom robotic systems. The problem is formulated as an optimal control problem for n-degree-of-freedom mechanical system models a semi-passively actuated robot. We take into account the inter ....etc

This project is aimed at tracking and having the view of the cubicle and the person sitting in it. Assuming there is already system that has the cubicle numbers and the telephone number data, at the same time this system will also need to take the floor plan as input and maintain the cubicle plan and the seat numbers. The floor plan input is needed to make
system more robust and adaptable to the new buildings coming up. ....etc
