Phozon rangefinder
@ June 22, 2010
Navigate around via ultrasound, makes funny moves and sounds when the obstacle is too close
Time to build:
4 hours
- Actuators / output devices: 2 GM9 motors from solarbotics
- Control method: autonomous
- CPU: Picaxe 28x1
- Operating system: undefined
- Power source: 4 AAs (1.2V each)
- Programming language: Basic
- Sensors / input devices: SRF05 from Picaxe
- Target environment: indoor flat surfaces
UPDATE
you can see the stupid moves i was talking about. In the first clip but the quality is not good(taken from my phone). Second video shows it navigating around my room
This is my start here robot. It uses SRF05 to navigate and avoid obstacles.
I removed the 'tyres' from the wheels and due to some reason and seen on the video yet to posted it produces a funny sound and moves awkwardly giving jerks while moving backwards when the danger level is too high (when the obstacle is too near to avoid it the robot moves backwards).

The jerky motion when moving
The jerky motion when moving backwards may be due to the balance. You could try shifting the battery pack forward or backward a bit and see if it improves. You could also employ a third contact point with the floor, like a caster, roller, or any round-bottomed object (e.g., a wide pen cap), which will give your bot a more stable stance.
Nice work on your start here bot!
