The Shield for Arduino has following interfaces:
1.
DC Motor Interface (Drives 2 DC Motors for Hobby Robots.
The interface is built around the L293D DC Motor Driver IC.
2.
Line Sensor / Obstacle Sensors (Attach 4 such Sensors)
Use these sensors to detect Line (Black on White) or any obstacle within 6cm range. This is based on IR Trans-receiver and a Comparator IC LM324
3.
The Buzzer or Servo Motor
Select the interface with the help of a Jumper. Buzzer can be used to generate Bips or simple tunes.
4.
The Switch or Servo Motor
Select the interface with the help of a Jumper. Use switch to start the robot or do some other action. You will have to write the code to read the switch.
5.
Two LEDs
Refer datasheet for Digital Pin I/O assignments and other details
Product Packing:
Product contents:
- One Shield board
- Four Sensor Boards
- Four Cables for connecting Sensors to the Shield

Question - by Arup

This is not not a problem but a suggestion. The servo supply is taken from the Arduino board. This supply can barely power a mini servo as its current capacity is limited. It may be better to connect the servo power pins to the external supply on the Robo shield board which powers the DC motors. I wanted to drive some servos I have which draw a higher current and had to rig up a separate supply before I could power them. It makes the arrangement very messy. If you have another email I can send you as picture of the solution. You may also like to see this link:

Well, received your feedback in another mail. You mentioned that you are unable to use some specific type of servos. The Shield can control any servo which works on PWM principal. The board supply 5V to Servos at max 500ma or even lesser depending of what otehr things you have connected to the main arduino board. The solution is simple, supply required voltage from separate power source to the servos + & Gnd terminal. Connect the Control line and Gnd line to the Shield. Thus the motor will receive required power from special power source and will be controlled via shield / arduino. Let us know the outcome.
