hello friends,

i am making a autonomous path follower and obstacle avoider, i want to use two servo/dc motors for two back weels and want to just attach a caster wheel for front wheet. so having a bot with three wheel , is any problem ?? what type of body should i build

??

OK first

what do you mean by path follower? what is the path?

three wheel bot is no problem.

I would recommend using HDPE for the material, buy it from McMaster

also what microcontroller will you be using? and what is your budget

hello friends,

iam making a path follower and obstacle avoidance system.i am new to robotics, i want to use two dc motors for two rear wheels and a caster wheel in the front.So my bot is having two motors and a caster wheel,total three wheels. Is my idea good enough to proceed

Don't double post

an any one tell me how to connect wheels to a motor

a regular motor or a servo . And also which exact motor and which exact servo

airman00 · « **Reply #4 on:** January 15, 2008, 08:38:35 AM »

as I said before McMaster.com

Also I would first build the robot and then program it.

Also, what is the path that it is following???

ruffntuff007 · « **Reply #5 on:** January 15, 2008, 08:43:39 AM »

the path is like B shape

ruffntuff007 · « **Reply #6 on:** January 15, 2008, 08:46:39 AM »

its a servo hs-35 ,torgue 4 kg . now can u please tell me how to connect wheel to that motor ?? wheel would be of radius 2.5 cms.

airman00 · « **Reply #7 on:** January 15, 2008, 08:47:06 AM »

a black electrical tape line?

lol

what is the path? out of what material , what color , what terrain NOT what shape

airman00 · « **Reply #8 on:** January 15, 2008, 08:48:11 AM »

here is a link on how to connect a wheel to a servo

Do some research before you ask questions like if three wheeled robots are ok.
The forum is FILLED with info on three wheeled robots...

the path is a track of 60cm wide . its a flat surface,wood made

airman00 · « **Reply #14 on:** January 15, 2008, 09:12:11 AM »

search GOOGLE!!!!

here is a robot that admin made :

I am working on a robot with two wheels and two casters, basically just for balance and to make room for my line sensors

Do you know how to track a line already?

ruffntuff007 · « **Reply #15 on:** January 15, 2008, 09:18:00 AM »

actually one of my friend is dealing with the programming part. i have taken the job to design chasis and essembling. do u have any other pic with a more of front look

airman00 · « **Reply #16 on:** January 15, 2008, 10:03:20 AM »

just search google for it , i am not going to

how will you be doing the sensors part?

If you want something cheaper than an omniwheel, you could also go with a ball caster.

SmAsH · « **Reply #18 on:** January 15, 2008, 02:47:23 PM »

yea i built the $40 robot and put a ball caster on front works well...

can i buy HDPE from home depot?

cooldog · « **Reply #20 on:** January 16, 2008, 11:19:13 AM »

A CHEAP SOURCE OF HDPE IS IN OLD CUTTING BORDS

SmAsH · « **Reply #21 on:** January 16, 2008, 02:51:54 PM »
