New Micro robot

Let's Make Robots Projects Showcase
1

Ive seemed to always enjoy how small people were able to make fully capable autonomous robots. So I decided to give my own version of it a try. I went for a small stack two inch breadboard modular design that I think has really helped with weight, size and aesthetics. This robot is based on the relatively new ATmega328 with Arduino bootloader. The chip is not shown in the following pics as im still a ways away in completing the main processor board for one I need to reorder the crystal as I bought a 20Mhz one witch the chip is able to handle but alass not the firmware witch is rated at 16Mhz.

A lot farther along with the base have the Motors, wheels and battery in place
Parts list so far:
2x Micro Metal Gearmotor 100:1
2x wheels 32x7mm
ProtoBoard - Round 2"
2x Arduino Stackable headers
Sony Ericsson battery pack recycled from a old cellphone 3.6V @ 950mAh
1x red led
1x Salvaged JST connection for the battery pack
1x ESD sticker to hold the wires in place on the battery pack :slight_smile:

Close up of motor mounts. I used a combination of servo tape and breadboard wire to hold on the motors as well as solid core wires to bring the motor connections up to the base layer.

A good view of the use of the LED as a caster and a power indicator, also the battery connection atm.

Be amassed at the compact processor board
More to come later but for now enjoy the pics and send any comments you may have.

Interesting 'bot! What language do you intend to program it with, and what tasks have you in mind for it?

I noticed two IR rangers, one above the other?

I plan to use C++ as the programing language as its a very user friendly and powerful language to use with Arduino processors. Not sure on the task its still in my vision to have a robot able to roam around my desktop. I plan to add a small OLED screen for relaying sensor information as well as displaying diff. faces to represent emotions throughout the day. I choose OLED for the screen for the vibrant picture for the amount of power needed as well as being light weight. sparkfun.com/commerce/product_info.php?products_id=8537. I envision it being scared of load noises and bright lights. I will also be buying a few more Gas sensors and have them hot swappable, who knows maybe one day it will save my life by detecting harmful Carbon Monoxide gas and or just let me know I left the soldering Iron on to long. It may also let me know that I have had a bit to much to drink with an alcohol gas sensor. :slight_smile:… The bottom IR is to mounted at such an angle that the robot will be able to use it as a edge detector. It has been a very fun project so far, I try to design very simple yet lightweight solutions for this robot for the lack of critical space.

Thanks for the reply
