Obstacle and edge avoiding robot
@ August 14, 2010
- Actuators / output devices: Tamiya twin gearbox, 2x Micro Servos
- Control method: autonomous
- CPU: Picaxe 28x1
- Power source: 4 AA batteries
- Sensors / input devices: SRF05 Ultra Sound, Sharp IR
This is my first robot, I built it five months ago, but I havan't had the time to smubmit on LMR. It uses an srf05 to avoid objects and two infraed sensors to detect edges. I made the head using perspex and used some Lego parts for the Chassis.

Nice robot and clever
Nice robot and clever solution with that arms.

i like the sensors
i used to play with bionicles and im sure that ive seen his "sensor wings" on one of them thanks for sharing this is a great robot

it detects using the LEDS

It detects using the two IR
It detects using the two IR sensors at the front. These are the same ones used in my line following robot.
The LEDs on the IR sensors are just to show that they are ON.

okay are the sensors sharp
okay
are the sensors sharp GP2D10 or GP2D12 ?

I really like the IR sensors
I really like the IR sensors on the... arms? antennae? whatever they are. Looks cool.
Does your code make use of the mobility of the IR detectors? It seems like it could be detecting front or side edges if it wants to.

Thanks, the "arms" were from
Thanks, the "arms" were from an old LEGO toy I had lying around.
The code doesn't make any use of the mobility of the IR detectros. The reason I made the arm this way was because my Electronics teacher gave us a limite on the size of the robot, it had to be less than 17mm X 17mm. The IR detectors had to be at leas 5 cm away from the robot, for it to be able to avoid edges and sence my robot was already 16.5mm long, I had to think of a way to break the rule "without breaking the rule :)", and thats when I came up with the idea of using two servos to extend the arms that hold the IR detector when the robot is turned on.
sorry for the long response :P
