Yet Another First Robot (yAFRO)

Let's Make Robots Robots
1

So, here's my first robot (yAFRO)

It has nothing exceptional other than running on Arduino instead of PICaxe and being built form an old snakes and ladders board. I choosed this track geometry to make it different than the usuall Tamiya tank chassis.

 

I still have much to do; the motor driver still doesn't work and I have to learn how to program the Arduino.

 

Since it's Arduino it can't be powered by only 4 AA batteries, do you have any good idea what type of battery I could use?

I chose not to use normal 9v batteries because I want something a bit more powerful, maybe 6 or 8 AA batteries, I don't know.

I'll update it when I have anything done. Maybe even some videos if I have it running.

 

*CORRECTIONS, I changed AAA for AA, my error.*

A simple "first robot" that navigates around using IR

  • Actuators / output devices: Tamiya dual gearbox
  • CPU: Arduino Diecimilla
  • Programming language: Arduino C
  • Sensors / input devices: Sharp IR GP2D12
  • Target environment: Indoor-the moon

There are plenty of

There are plenty of batteries to choose from. Pololu have many, or you can just go to a local model car shop, they surely have great choice.

Nice chassis, looking forward to see it completed :slight_smile:

power

I am not sure if you have seen the battery backpack for the arduino. i am just learning all this too, but i think that it will meet your needs to power the arduino, but I plan on using other batteries to run the motors.

Liquidware : Lithium BackPack

What I did for power
I used 4xAA for the servo power (which I attached to wheels) and a 9V for the Arduino. It has the added benefit that I can disable power to the wheels while programming/testing.

**beautiful design!! **

beautiful design!! congrats :wink:

i guess you can use a 9V battery for the Arduino and sensors and 4 AA batteries for the motors

I’ve considered RC Hobby

I’ve considered RC Hobby batteries (NiMh or LiPo) but I didn’t want to buy a charger for them my budget is relatively limited.

 

thanks, for your help though.

I have seen the Lithium
I have seen the Lithium backpack, it’s too expensive to me, the arduino cost about 30$ and the Lithium backpack is 47$ but it can be charged via USB wich is very cool.
