Electrical Design updated
Tuesday, June 2nd, 2009Simple Infrared sensor for encoder
Tuesday, June 2nd, 2009Here you can see IR sensor schematic.
I used two IR LEDs, one as detector (D1), another as emmiter(D2). The sensitivity could be adjusted with trim-resistor.
VDD - 5V
The signal to the microcontroller can be taken just before or after the LED1.
Here is the foto of the board.
Mechanical Design update
Monday, June 1st, 2009Description of my new mobile robot is added to “Mechanical Design” section
My Mobile Robot Development
Monday, June 1st, 2009Here is the robot I work now on:
Front View
As you can see on the picture it has caterpillar chassis for better passability, 2 degree of freedom turret with two cameras installed, one camera for teleoperator other for internal AI usage. For navigation purposes electronic compass was installed connected to Arduino controller, as a power supply NiCd battery is used, mounted on the lower deck.
Side view
The camera with antenna is the one for operator’s use.
Top view
On the top view one can see two motors for propulsion, motor control circuit and below the motor control circuit you can see Arduino board. Below you can see motor controller closer.
