Let's Make Robots!

Arduino Android

Remote control or obstacle avoidance

The other day I was staring at my trash bin and there's an idea comes up in my mind. Since my wife is not home for while I think I should be able to do something about it. So, here you go. The progress of how AA was born.


Once upon a time, he was a trash bin:

Cut some spare pipe and cut 2 balls into half:(did I say 2 balls?)

Put wheels at bottom and he get new feet:

Seal the head and hand, also put servos into arms as joint:

Give it some color and cut a square on body to fit the brackets:

OK, we almost got the shell done.

Now step into electronic parts, (upside down the body, does this looks familier to you?) I use Arduino Mega and 2A H bridge.

I modified the head to make it looks more rusty and old style. Using RJ45 to connect 2 RGB LEDs as eyes.

Since the head modified, I should make the body old and rusty too. I drill a hole so I don't have to take out the Arduino out everytime I update the program. The door was using magnets(4 inside and 4 on door.) because I am lazy to do anymore screw works.

This is how he looks from back (R2D2 mutant now?):

In the front, I cut more holes for LCD and 2 range sensors and paint it in black so it looks like a belt and give it a bit stylish.

2 switch for main power and motor battey at back.

A shoot inside AA:


Here we go, AA is alive.

AA will have 2 modes to switch in between AUTO/MANUAL control.

I know it's probablly too much photo here but I want to give you more info and instead of my terrible English I am afraid won't be detail enough for some of you so I rather use photos to show you how it been made. Hope you enjoy it. :)

Before my wife come back from Taiwan with my new born son, I only got limit time to enjoy this robot making time. I don't know if I can make other furniture into toys.

Wow! Thanks for your helpful hint!! I love this big huge clear image. Since I am not a engineer, this kind of image helps me a lot. The last point, do you mean adding a 2200uF capacitor on arduino power + - pin?

Yes. if the little capacitors don't solve the problem then try adding one or more large capacitors in parallel with the battery.

If possible put one on the Arduino where the battery power comes in, one on the motor controllers power inputs. Heavy duty power cable from your battery, to these capacitors will make a big difference.

OB1 - You FreeForm MadMan You ..... this arrangement should be obligatory for all servo cables.....
