Motors

I want to build a small robot, how do I know what type of motor to buy, and how do I mount it?

Here is one place to start learning: http://www.societyofrobots.com/robot_tutorial.shtml

Thanks, but I really am new to this, if I want to build a robot, what motor should I use, and what mount?

This is the second post you’ve created asking someone to hold your hand. I have yet to find any forum or discussion board that will tell you what you want. You sound like you’re a child and if this is the case, please start doing your homework. If you’re an adult, instead of asking these childish questions and not wanting to actually learn, then ask someone to research, design, build, then program a “robot” for payment.

I recommend the Pololu Zumo or 3Pi for starters. The Pololu engineers have already made all the difficult decisions, the robots are well designed and produced, they perform well and are relatively easy to program.

Are they ready made kits?

Okay, forgive me for asking for help on what seems to be a help forum, do I need a degree to post here?? So I am a newbie, I find your comments a bit attacking. I am very new to robots, I thought a few people with lots of experience would be willing to help me.

No, just knowing the magic word “Google” suffices in most cases. If you had entered the text “Pololu Zumo or 3Pi” in it you’d find their forum as the first link, and a product description as the second. Surely that would explain if it is a ready kit or not.

If you decided that you only want to start building a robot from scratch instead of a pre-designed or assembled robot then you have chosen a very steep learning curve for a beginner. As entry models those kind of products are a smart thing to start with. Once you get the hang of programming those and using it’s sensors to operate the actuators’/motors/whatever you are better prepared to start choosing your own parts. Because you’ll know (better) how they operate or their strength and weakness.

Also do not forget the learning and tutorial section of SparkFun. It gives plenty of examples and hookup guides to their product to build stuff like that. And you don’t have to buy their products. Just take them as inspiration and get comparable things from other vendors. But I guess that is not politically correct to say in a vendor’s own forum.

Also the thing is this: You ask for specific motors or mounts. Well, it depends! How big is your robot? It’s weight? What does it carry? Only sensors (if so which) or what payload it is carrying. Is it externally powered, or does it have to carry it’s own battery. Does it have to function off-road outside in the yard, or inside the house on a flat polished floor, or rough carpet. Well, all those questions lead to circular reasoning. Because bigger motors result in heavier motor-drivers and motor mounts. Which leads to heavier weight of the robot and the design-circle continues. And all those design requirements of what the robot must do or be is something that you did not add to your initial request. So those that responded before me just gave a general answer, to look up and learn what rules the design choices you need to make. There is no simple answer to your question what motor fits best. Especially if we don’t know what a small robot should be.

Is the OP a troll?

Maybe, I’m still in the X-mas spirit and give the benefit of doubt. But I do that all seasons of the year.

Sorry, I probably didn’t give much detail:

It is a small robot

I agree, I should start with a kit.

I don’t know what to Google.

Sorry if I am asking questions that have no one answer.

Also I’m not a troll, sorry if I appear as one, I am just very new to this, so if I seem like I don’t know what I’m talking about, it’s probably because I don’t. I will try a kit, but I have some ideas for a robot, I just don’t know the technical stuff. I should probably come back in 6 months when I know what I am doing. Sorry again if I seem to be asking questions that require more information than I have given.

Is it actually possible to build a robot from scratch of you don’t own a 3d printer or a laser printer? When I rule the world, free 3d printers for everyone! And free cookies!

A lot of the tutorials tend to use kits. But I understand your point.](http://lmgtfy.com/?q=I+want+to+build+a+small+robot)

You can glue a motor case to a piece of wood, cardboard or a empty piece of perforated PCB. Tie-rips do the rest. How did you expect this hobby community to flourish before 3d printers were more than an imagination. It won’t be pretty, but it will get you going.

What are tie-rips?

My bad. It goes by different names apparently. Tie-ribs or also tie-wraps:

Or zip-ties as they are called in the south.
