    Default New Robot Kit - Questions *Imp*

    Few days back i had seen one of my friends bot which i found quite interesting and adviced him that he can make some money out of it while helping a lot of people. So after configuring his bot for more of a General purpose platform he is planning to enter the indian market in collaboration with RI / MIGI .

    Here is the basic config of the main Board which can also be used as a dev board

    PIC 16f877 based
    UART
    One Pair of RF modules
    Three pair of IR modules for object avoidance and Communication
    3 IR LED Detector
    2 Metal Bunp sensors
    1 Piezo Speaker
    2 CDS Light sensors
    Dual power supply for Motors and uC
    1 HBridge Driver with soft PWM
    A Breadboard is mounted on the PCB for additional experimentation
    A few LED's , Restistor, Caps , Coloured wires and screws to have fun around with and hasall IO lines open for extension

    The robot base on which the base board is mounted using screws

    1 Metal chassie for mounting everything
    2 Good quality DC Geared motors
    2 Wheels with optical feed back for dead recknoning

    S/W side

    Custom IDE with custom BASIC interprettur for starters with built in Burn functionality .You can also reporogram it like a normal PIC.

    He says you can build the following bots easily with this one

    Bump Bot
    Obstcale Avoiding robot
    Line follower
    Light follower
    Fire Fighting
    Remote controlled Bot ( IR / RF )

    And for the advanced thing you can do the following

    SWARM Robotics , Maze solving , Balancing Bot( Gyro addon required ) ,Path finder , ROV bot , Remotely programmable bot

    According to him it takes 1/2 an hour from opening the package to get it running around.The config is aimed at people who dont know robotics and have never touched electronics. The aim is to provide a bot for starters to intermediate bot builders. It will provide everything that a normal guy will ever want to build into a normal bot, And he can build bot with minimal hassel. And as its more of a dev board on wheels there is no limit to what you can achive.


    So now my question ?

    Q1. What more improvements can he put in ?
    Q2. How much will you shell out to but it ?

    Hi Vikas!
    Good attempt and a good assembly of the works in a single hamper! I must congratulate the maker and the finder!!

    I did a quick calc. and feel, in my personal opinion, anything from Rs.2499/- ( with Labour, Brain, as charity ) to Rs.4999/- ( can keep the Wolf at bay!!) should be a non-commercial costing.

    The 2500 is a magic figure and should be affordable by 20% of the people who are 'dying' to make a robo.

    Ofcourse, there will be detractors who will cry "expensive" and go ahead spending more than this by themselves, with unpredictable results.

    I say, Go :!: javascript:emoticon(':!:')

    Hi


    Yep the Aim is to bring is b/w 2k -> 4k. I also searched around the net for such kits and found them quite expensive ( about 200 $ on an avg ) so around 10k in India, So i said if he can bring it out itll be a great in both price and performance. Also itll be good for the community as u might end up spending more on a uC based Simple LFR if ur in-experencied.

    have you done something with the php sw
    Yep im a expert in PHP and other LAMP technologies and have done lots of work. I also offer consultancy services in it too.

    What does the bot use for the rf communication? Those normal 433MHz rf RX/TX modules or something more interesting? Is the communication 2 way or ony computer to bot?

    Can't be anything else. Anything more "interesting" will involve unnecessary software and port pins. This will complicate the beginners learning curve.

    The "Pair of" means a Tx and an Rx. You can connect anything anywhere- PC to Robo or Vice versa.

    It contains a single pair RX/TX of i think 4.8k data transfer rate , Its single way communication which is enough for a beginner / intermediate user.

    But if someone like a college / group of people buys more than 1 bot then you can easily build a transciever or build advanced things like a swarm etc.

    Perhaps adding a sonar range finder would prove to be useful. It would free up the IR for communication use and extend the number of things that can be done with the robot. I dont think it would be too expensive either, probably about Rs 200 extra or so.
