This is the beginning of my ROS enabled robot CATHI. She's a beauty, and this is only the beginning. I'm having a blast with it!

ROS is Robot Operating System? What does it run on, any lineage?
Do you mind sharing how much $ you have invested so far. It looks impressive, but can I and others afford to do something similar?
First computer 1959. Retired from my own computer company 2004.
Hardware - Expert in 1401, and 360, fairly knowledge in PC plus numerous MPU's and MCU's
Major Languages - Machine language, 360 Macro Assembler, Intel Assembler, PL/I and PL1, Pascal, Basic, C plus numerous job control and scripting languages.
Sure you can learn to be a programmer, it will take the same amount of time for me to learn to be a Doctor.

An impressive beginning. Does CATHI have an end goal or is it just an experimental rig to get to learn to use ROS in an indoor setting. Whatever, its certainly a bot to have some fun with 😀

@zander ROS is Robot Operating System. It's hard to tell the cost, I've sort of collected the parts over the years. The base chassis is black acrylic and Actobotics channel and xrail (servocity.com). The brain is a Nvidia Jetson Nano 4GB, the sensor and motor microcontroller is an Arduino Mega, the motor drivers are Cytron MD10C. Wheels are 4" RobotZone in the front with omni wheels on the back (2 paired to a side). Then there is an RPLidar and a generic webcam along with a 7" Raspberry Pi HDMI screen. I'll be adding more parts of course, but that's what I started with. Maybe $500-$600? I'm going to give a tour of CATHI's parts soon, if you need part numbers or whatever I'd be happy to let you know. I do know that Jetson Nanos are tough to get now due to a chip shortage.

Edit: Forgot to mention two GoBilda Yellowjacket motors.

@jeffreyjene Based on the parts mentioned the price sounds right before the shortages drove the prices crazy. Is there something special about the Jetson or can a Pi be substituted easily.

@zander The Jetson is superior when it comes to visual imaging than the Pi and I plan on using a lot of OpenCV. Also, it was sooooo much easier to install ROS on the Jetson.

@jeffreyjene I will have to check it out.

I love it .
I do too!
Curious what kind of battery pack you're using to power this?

@dronebot-workshop It's a 12V 3000mAh Matrix NiMH battery. I'm using two different buck converters for the components, one down to 5V and one to 3.3V. There's probably a better way to do it. I really would love to figure out how to make a permanent charging port affixed to the back, but I haven't gotten that far yet. Forgive the spaghetti wiring, please. This was an early photo.
