Mr. Cheese Can

You can buy German Cheese in Shanghai, sealed in a nice aluminum can. Since a while I toyed already with the idea of doing sth. with these cans. Too good to throw away. I also had some parts and wheels from a Chinese LEGO clone called Ban Bao as well as two micro gear motors around, so I started to build a 3-wheeled light robot platform.

Using my clothespin gripper...

... and a lying 7-segment display below the SRF05, the robot takes shape:

The control of the 7-segment display is similar like for  Mr. Sunsmile with a diode matrix, a CMOS decade counter/divider 4017 and a Picaxe 08-M. The robot [head] can express following moods:

:D

:P

A close-up of the interior of the robot head:

2010/4/26: Had time in the fast train to draw some circuit diagrams. Attached you find the 7-seg control unit and the reflection light barrier, which I am using to trigger the gripper.

Home-built tactile sensor:

2010/5/1: Mr. Cheese Can is so far finished, now I have to program him.

Navigates around via ultrasound, makes :D :) :( :| or :P, tries to catch everything nearby with its gripper

I’d love to see video,

I’d love to see video, especially of the gripper working.

Gripper video is already

Gripper video is already available :slight_smile:

Nice work as always! :slight_smile: How

Nice work as always! :slight_smile: How are these motors? I just got some myself, and have not yet tested them?

**The gripper is clever! :slight_smile: **

The gripper is clever! :-)  Very nice job.

Bought a couple of these

Bought a couple of these motors here in Beijing Rd., Shanghai (also called the Street of Electronics), and I am quite satisfied. Very small, powerful, complete metal gear and they draw only 10 to 20 mA @ no-load. Perfect for small, light robots. Be only sure, they all have the same gear ratio. Better you test them before you mount them :smiley:

nice gripper

İntelligently degined , good job…

Nice I can’t wait for video

Nice I can’t wait for video of the robot in action

 

It’s an imazing idea,

It’s an imazing idea, Thanks

I’m wating to see the video

by the way I’m new and I’m really interested to make a robot
