========== ABOUT ME ==========
My name is Kajal Gada. I am a Robotics Software Engineer and a youtuber. My goal is to develop algorithms for realizing robot operations in the real world. And it is just absolute fun to code and solve problems.

I started my journey in Robotics by working on small personal projects such as a line follower with an arduino. I then pursued and graduated with a Masters in Robotics from University of Maryland in 2017. After graduation, I have worked at Reality AI, Qualcomm and Brain Corp.

I am also a YouTuber, it is my way of giving back and helping the community grow. As a women and an international student in the US, I am aware of the challenges to break through and have a successful career. I share my insights and also teach robotics through my youtube channel.

========== Gear I usually use ==========
🍋 Camera: YI 4K Action and Sports Camera
🍋 Camera: iPhone XS
🍋 Tripod: Ravelli APLT6M 72" Light Weight Aluminum Tripod
🍋 Lights: Neewer Ring Light Kit
🍋 Mic: SoLID Lavalier Lapel Microphone
🍋 Recording: Voice Memo App on iPhone or Mac

Greetings, excellent presentation, Jairo Posada writes to you from Cali, Colombia, we are simulating manual remote control of a robotic arm with ROS2, but it does not work for us, could you please guide me on the matter, that ROS2 has a difference from ROS1 that we do not know how to run the program, thanks in advance for your help, a hug.

Hi Kajal,

is it possible to make a video on Expanding on Ros2 interfaces.

Thank you.

[chetankumarpatel]

Please make a tutorial on ros2 launch files also

[reshmadhotre]

Any way to test the ROS2 parameter, set parameter and get parameter, change the values and check them

Why not install ROS2 on Mac OS? Please publish a tutorial on installing ROS2 on a Mac operating system (Big Sur) in a video?
