Robotoy V3

[chipwich]

Here's my take on a simple microcontroller driven autonomous robot. The PICAXE and L293D motor controller are mounted on veroboard (stripboard) with screw terminals for the motor hookups. But because I always think that I might want to add just 1 more feature, I mounted the I/O devices (LDRs, LEDs, and piezo) on solderless breadboard.

The motors are driven by a simple photophile (or photovore) algorithm. It's pretty neat how 2 simple LDRs can provide some semblance of object avoidance. It's also fun to drive it around using a flashlight. It stops randomly to play any of about 20 different tunes, then continues on its way.

Information, code, schematic, and a video are at: http://corticalcafe.com/picaxe_robotoy_three.html

Fun bot! Submit it as a project in the contest next cycle (too many robots this go round!). BTW, the Youtube listing has a bad link to your website. Cheers.

Thanks much for pointing this out. Perhaps one day text entry fields will have link-checking in addition to spell-checking.

Which type of micro controller you have to use this robot?that means PIC or 805 or AVR which controller use this bot? and you told LDR that means LDR sensor. its need to detect where high rays falls on earth? what is the use LDR for here?

Since this is the PICAXE Forum, I guess it's PICAXE!

LDR=light dependent resistor. We old guys call 'em photoresistors or photocells, much less pedantic IMO.
