That's a really good demonstration in an environment with plenty of complex shapes and challenges. You have clearly shown the processes involved, along with a great schematic of the machine. Many thanks for the video.
Your project inspires me. I've already built this robot 95%. However the movement (especially acceleration/deceleration) is quite slow. Can you share the ODRIVE's configurations ?
I'm not really doing anything special, just follow the normal ODrive configuration. You can increase the maximum current and increase PIDs to make it "snappier".
Hello Priit, thank you for sharing this video! It looks good for learning and building ROS2 robot! Could you please share some info about what this robot is capable of and what could be enhanced? Thanks in advance! :D
Looks like a great project. Did you connect th oDrive directly to the Pi with USB or did you connect it through the Adafruit Feather nRF52840? Could you eplain that part? I want to build a bot with Humble and not having rosserial seems like a huge problem. Thank you for your time and the great video.
If you mean using steppers instead of brushless motors and ODrive then sure it should be doable and cheaper option. Would need different control software stack.
@@badsham227 Haven't really tested. Currently the rear axle is held in place with small 3D prints. Replacing these with stronger ones and also making the front caster wheel mount stronger could make it carry considerable weight.
The robot does not currently use a camera but rather uses LIDAR and odometry for mapping and navigation. Any camera connected to the Raspberry PI would work.
There's a bill of materials in the Google Sheets document that I shared. It adds up to around 1500€ depending on which parts You use and where they are sourced. The Lidar is the main cost, there are cheaper ones. Could probably also swap out the fancy brushless motors and ODrive with steppers or DC motors with feedback to reduce costs.
Who ever did the wiring on this, robot should be awarded Robot maker of the year.......Looks very neat and very well made
Thanks :)

Amazing ! Looks like an artist.
wow
Thanks for this good demonstration.
I am very impressed with your project. I also want to control bldc with odrive. Can you tell me what encoder you used?
The encoders are TLE5012B from Aliexpress.

It's a base platform for learning, You can program and extend it to perform any task needed :)
almost as good as amazon's pick robots, nice!
Thanks for this.
Awesome 😎
👍👍👍👍

It directly connected with USB. The nRF52840 was added for future expansion and not used in the robot as shown in this video.
Does it is possible to control step/dir servo with ROS2 and what hardware interface would work
If you mean using steppers instead of brushless motors and ODrive then sure it should be doable and cheaper option. Would need different control software stack.
Just wondering how much payload this car could carry with what speed? Did you test that? Thanks
yeah same question..what's the max payload?

hiwhat camera do u use for this robot
The robot does not currently use a camera but rather uses LIDAR and odometry for mapping and navigation. Any camera connected to the Raspberry PI would work.
Hey, What purpose Adafruit Feather nRF52840 Express is used for Rosbot?
Currently none, was added for future integration of hardware.
How much does the parts cost ?

@@kallaspriit Thank you for a detailed response
