|PWMbug; Robot Bug with DC Motor speed control|
Posted by ozkal on Thursday, August 04 @ 03:16:53 EDT (13671 reads)
|After a long delay i'm back with a new project. PWMbug is a robug with a microcontroller that applies PWM speed control to its two DC motors. The output power of the PWM signal can be adjusted by pressing the two buttons onboard.
The bug continuously moves forward avoiding obstacles by the use of its touch sensors. The speed of the bug can be adjusted (8 bits - 256 steps) from stationary to %100, which is around 10cm/second. And this is the first project on this site which has got a C source code. All source and the ready-to-program hex file is also included.

|These are the new bug photos submitted by our visitors. |
Here we start with Murat Şen's Lightbug, he had used the schematics and source code of our lightbug project. Additionally he had designed his own PCB and built the bug on his own design. Nice project, Well done.
And this is fertetre's probug,

|Line following robot; Linebug (Videoclip & Circuit Schematic is added)|

|Linebug is able to find and follow a 2-3cm thick black line drawn over a white surface. 4 IR sensors are housed in a black, plastic box and their signal levels are compared by 4 separate op-amps. Op-amp outputs are then fed into the microcontroller (PIC 16F870) and the micro drives two motors to enable the robot first find, and then follow the black line.|
Do you think Neons are only used in Tuned cars? (Auto tuning, power tuning, vinyl tuning etc.) Sure not! Here is our Linebug with its white Neons. Linebug is able to control its neons; can turn them on or off, can give them pulse effects with slow or fast changes, can fade in and fade out them or simply hold their intensity level constant.

|Temperature sensitive robot bug ; Tempbug|

|This robot has got an onboard temperature sensor and a 3 digit LED display to show actual temperature around. First i wanted it to move to hotter or colder spots but though the response time of the sensor is too long, the scheme didn't work satisfactorily. I'm now thinking of new behaviours associated with temperature.|

|Robug of the dark nights ; :) ''Nightbug''|
Posted by ozkal on Monday, January 10 @ 07:34:47 EST (7451 reads)
|Here is the colourful, soundful and cheerful robot bug of the nights : Nightbug :)|
Nightbug is a robot bug assembled on a multi holed prototype board. The upper body of an old mouse is used as the shell of the bug. There are two sound sensing circuits at the open sides of the outer shell protruding towards the outside, facing to the front. There is a 3.6V ni-cad battery which is permanently glued to the inside as the power source. The brain is a PIC 16F627 microcontroller. There is a blinking superbright RED led under the hood at the back which gives a nice impression at night. And a super bright blue LED at the front as a headlight which illuminates where the bug goes.
When the robot detects a sound from both of its microphones, it looks for the phase shift between the signals. And by this, the robot gets the idea of the direction where the sound signals come from. Then turns towards that direction. If the sound comes from the front, the bug goes a step ahead. This process repeats until the robot finds the sound source.
The article continues with more pictures, linksto the assembly code and the circuit schematic of the project.
