Hello Everyone.
I am new at robotics and I want to start putting together my first robot.
I will be using a DFRobot Romeo V1 All-in-one Microcontroller (ATMega 328).
I want to incorporate two main functions:
Obstacle avoidance and following a black line path.
I was wondering what ultrasonic and infrared sensors would you guys recommend for these 2 type of tasks?
Also, I plan using two motors to drive the robot. However, I am not to knowledgeable on this. Do I need some sort of wheel encoder if I want my robot to be able to turn?
Thank you all. :D

;) Hello,

You are very welcomed here, feel free to ask about anything!

To your questions:

1 the sensor shoosing

You can use theLine Tracking Sensor for Arduino and URM37 V4.0 Ultrasonic Sensor to realise your start-idea.

They have theirself wiki to help you quick start on your Romeo.

2 Actually, you don't have to use the ecoder, that is to help the robot to walk/run straightly, and it will complex the code, make it harder to begain.

Btw, there is some kits which including some sample sketch may help a lot! They are:

Finally, this 2WD Mobile Platform would help you to build your robot easier!

Looking forward for your update of your Robot!

Thank you very much for the information. Truly helpful!
If I may also ask, as far as the line tracking sensor and ultrasonic sensor, do I need more than one? meaning, will using 3 or 4 line tracking sensors instead of 1 improve the robot's performance at that task, or the increase is not worth the extra sensors?
Also, I just realized that there is a new Romeo BLE. Apart from the Bluetooth capability, is there any other extra benefit when compared with the V2 or V1 model?
Thank you again for your time and help!
