Commercial Robotic Lawn Mower

Hi, I am Embedded System Design and Development Engineer. I have expertise in Microcontroller Programming and development on AVR (ATmega and ATtiny), Arduino and ARM (Cortex M0 and Cortex M4) in C/C++/Assembly Language. I have done - Control of DC motor, Display on LCD and input from Hexpad - RFID Based Factory Automation and Remote Inventory Management. - RFID Based Loyal Card for Loyal Customers. - Bluetooth Communication between MCU and RFID Host. - Vehicle Tracking using GPS and Accelerometer. and a lot more. I have expertise over all communication protocols of Microcontroller: - SPI (Master/Slave) - UART - USART - I2C (Master/Slave). - Ethernet - Wifi - Bluetooth etc.. I am expert in interfacing sensor modules with microcontroller. I believe in providing superb quality provided that the deadlines are met. Moreover, during the course of my project I would keep you updated regarding the status. Looking forward to hear from you Regards Khawaja Muhammad Abdur Rehman

Hi , I am intrested in this project , I have good experience of product development , I would like to discuss furture details of the project Best regard Dost Shah

Hi there. My name is Keith and I am a professional electrical engineer here in the US. I graduated Vanderbilt University with a BS in mechanical engineering. I now work solely as a contracting designer and freelancer. I am knowledgable in all sorts of microcontroller implementations, circuit design, sensors, mechanical systems, wireless and more. I am hardworking and understand that when all is said and done, my clients need a product that works well and done direct to your specifications. I invite you to have a look at my profile resume and portfolio. Thank you for your consideration! - Keith B

Hi! I'm a professional embedded systems engineer, currently working full time in a dental systems company developing firmware for dental care units and chairs. I'm looking for interesting projects to participate outside of my daily job. This seems to be a challenging and interesting project I would like to be part of. I am experienced in both software and hardware engineering, and products designed by me are being used by satisfied customers in many countries. I reviewed the website and the documents, very quickly, but here are some things I personally would change: 1. Would not use an Aduino board. the pre-built Arduino is very expensive to be used as a "controller", and there are much cheaper alternatives to the ATmega1280. Also there are lots of better microcontrollers for this kind of application, for example Freescale produces excellent automotive microcontrollers that are much more suited for this project. 2. The motors draw lots of power, so the power consumption needs to be as low as possible. Batteries are also expensive, so there are potentially big saves to be made. As it seems that the ArduMower is designed with more hobbyists in mind, it seems that the overall component choices could be much cheaper. 3. I would design the pcb to have separate control/power stages with separate ground planes. I would like to hear from you and your ideas about the project. I can design software and electronics, but I dont have much experience in mechanics design. Thanks!

As with many projects, the lawnmower has been put together mostly using off-the-shelf components such as the Arduino board, remote control links etc.. Most of these items are relatively expensive and so the total current component cost must be substantial. To commercialise the lawnmower you will have to design the system as a whole taking advantage of the lowest cost components, and the experience already gained from working on the project so far. Some items, notably software, will be reusable or at the very least will form a strong starting point for the final design. I would expect to look closely at the following items: 1. The overall system with a view to integrating into a low cost bespoke electronic system. 2. The expensive items such as the motor and their drives, and the sensors. 3. The software. Is it written in C for example which can be ported to one of the many available low cost (and powerful) microcontrollers. I have over 30 years experience in electronics design including analogue electronics, interfacing, digital technologies and microprocessors/microcontrollers/embedded software. I have designed many pcb's and I understand and have worked on motor controls and various sensors. I have worked on industrial, commercial and military systems. I have my own electronic products which have been commercialised and proven successful. I feel certain that I can contribute to your project. I am University trained and a Chartered Engineer. Happy to discuss further.

hi, am a tenacious mechatronic engineer, i have a 7 year experience in electronic design and pcb layouts. i also have an aptitude towards robotics and programming. i have a three year experience in robotics and an expert arduino programmer. am very good at eagle pcb,Ni multism and ultiboard,as well as proteous isis and aeres. i am very familiar with autodesk inventor and have been actively involved in mechanical design for five years now i have designed and implemented a very sophisticated robotic arm with arduino having designed part for myself. i can do pcb design for integrating all the arduinos together instead of doing all the wiring it becomes very hard to debug. i think your project is very interesting and i would love to see you through to nothing short of success.

I am an experienced engineer working with a team electronics professional who are well experienced in Electronics Design from Concept Upto disposal level design

Hi I have read and understood your requirement, I have prior experience required and I can do it in a stipulated time frame. Please do award me the project Regards Iftheqhar
