Title: need help please.. about your robot (adaptive mapping)
Post by: learner on April 02, 2008, 08:10:12 AM
sir, I'm a newbie here.. this is my first time in making a robot.. please tell me step by step on how to make an adaptive mapping robot without using the irobot.. I'm making a robot from a scratch, from designing to making sensors, wires, etc.. please help me.. i have proposed already a proposal about this project and been accepted already by my professor.. i ask an opinion from the shop and told me that i must use a gps, servo motor, stepping driver.. i don't know what i lack and how to connect them..

It's been asked a lot if you can use a gps with this kind of thing. A gps just isn't accurate enough for a small space, (such as in a room). You don't need a "stepping driver" actually, I don't know what that is. What you need to build an adaptive mapping robot is....
a sharp IR rangefinder http://www.pololu.com/catalog/product/136
a microcontroller http://www.societyofrobots.com/step_by_step_robot_step3A.shtml
3 servos http://www.servocity.com/html/hs-311_standard.html
wheels http://www.pololu.com/catalog/product/226
batteries http://www.all-battery.com/index.asp?PageAction=VIEWPROD&ProdID=495
you could also use the Arduino as a microcontroller http://www.moderndevice.com/diecimila.shtml
Have I missed anything? Oh, yeah you also need a charger... So do some research and search the forum!

If your using servo motor, then you wont need a stepping motor driver. You would either try to drive the servos yourself or use a servo motor driver.

You would use a stepping motor driver if you were to use stepping motors.

Check out the $50 robot on this site, as well as reviewing the wavefront pathfinder tutorials, these should help you with starting off with how to put a robot together and how to implement basic mapping. For adaptive mapping, you probably want to search the forum for subjects like "slam", although nobody really has this as a perfect art form yet - it is still an ongoing development in both hobby and professional designs.

But seriously build the $50 robot then you will have a basic robot to learn from and something to use as a test platform
