Hi all..Nice community here!!I am an arduino newbie.I bought a starter kit that includes an arduino,a speaker,an lcd screen and some leds and i had fun playing with them but now i want to make sth like a robot which will have wheels or sth to move...What i should buy?What servos/sensors/hardware?I am a newbie so if u can please tell me...
Thanks in advance.Keep up the good work!!!
Best thing to do is search robot sites, use google, and do some up front research on the type of robot you want to make. Once you have a specific type of robot you want to build, then start looking at how the arduino will be able to control the various robot components.
Well i would like a wheel-moving bot that can move based on sound or distance got from sensors...
I cant find what do i need to get movement.I need servo?Motors?An extra shield?Please help as long as you can...Thanks
I've used slightly modified RC servos direct-driving wheels on a few robots (Parallax BOE-BOT, and the old Innovation First/Radioshack VEX, interchanging and crossing between the two platforms.)
The modification requires removing the 'STOP' tab on the final drive gear of the servo, as well as replacing the 10K 'Position' POT under it, with a 10K trimmer. Objective, is making the servos go from their stock 180-degree fixed, to a variable speed constant rotation.
from there, you simply send a PWM signal to the I/O port connected to the servo for a variable speed in either forward (could be higher or lower) or backward (lower or higher) rates.
I've been trying to find time, mainly, but have the ideas already jotted down of a small mobile robot (track driven) that'll run the VEX frame/drivetrain, using ideas designed/tested for the Parallax Basic Stamp-2, but using the Arduinio as the 'brain'.
I have all the parts, just never enough time to stop and put it all together.
I've also been wanting to build an Arduino robot. I've been eyeing the Micro Metal Gearmotors at SparkFun
Something like this might be a good base to start on

Something like this looks like a good battery holder. There are others shapes and sizes you can find too
I think you would also need a Motor Shield like this

I'm not sure how the motor shield works and how you are supposed to connect other things to it as I am just exploring the process of building an Arduino robot myself. I'd like to be able to use IR sensors, antennae feelers, and or a Wii Nunchuck to control the robot, but I have no idea how that could be done yet.
I hope my product suggestions are helpful. I'm curious to see what kind of robot you end up with as I also embark on my Arduino robot making journey. Good luck!
