Navigate around via ultrasound,
Cost to build:
$100
Time to build:
10 hours
- Actuators / output devices: Tamiya gears and tracks
- Control method: autonomous
- CPU: Picaxe 28x1
- Sensors / input devices: SRF05 Ultra Sound
- Target environment: indoor
Update: new photos
Made this one while waiting for my servos from China (about 6 weeks now).
I've found the tamiya tracks aren't up to the task, so I don't think he'll last too long befor being recycled.
sorry for the picture and video quality :(

servo
AWESOME design!!!
what kind of servo are you using to move the head?

Awesome! - I love to hear
Awesome! - I love to hear the sweet pitter-patter of baby tracks. Lots of character!

Looks like polymorph or
@ Wed, 2008-10-01 20:48
oh...so it sticks well onto
@ Thu, 2008-10-02 00:23
It is polymorph, and it
It is polymorph, and it seems to stick to other plastics really well, I did have one of the shaft mounts come off, but just drilled and tapped it so I could bolt it back on.
If you do have to drill or machine polymorph, I found that the harder (colder) it is, the easier it is to work with.

Once again great design! You
Once again great design! You seem to have a knack for creating expressive robotic caricatures.
Are the cogs all press-fit onto the shafts? Are you using motors from the same company too?
@ Thu, 2008-10-02 00:20
press fit
The cogs are press fit on to the shafts, the drive shafts are a hex type shaft, and the free turning ones are round. The gogs that go into the hex shafts arn't very strong, so I've had to use hot glue to make them stick.
Both the motor/gearbox, and all cogs and shafts are Tamiya.

I would really like to see

tracks
I had to use two packs of tracks to get the length I needed (twss), but they are some kind of rubber material (don't really know what it is) and they stretch too much. So they are either too tight to turn initially, or too loose and slip off the drive cogs.

beautiful
You're getting 5 stars for creative use of materials and good looks
