It’s time to continue with the MOOC DuckieTown course and bought the newest DB21J (4GB) DuckieBot.

Although I considered to buy an older (& cheaper) RPi version, the newest version should be less stress full, since it (should) work with the newest online course. And I want to learn from real robotics behaviour, which will be different then the simulated version..

First impressions:

  • I realy like the online-documentation (building/setup).
  • I started 2022 MOOC already, it is free to access and having great content.
  • Shipping the DuckieBot was relative fast (China → Europe).
  • Building the DuckieBot was quite straight forwards too.
  • Installing the laptop/flashing was also straight forwards (so far).
    (To bo ounest, this is what I was dreading the most.)
  • Could not buy EU version. So I having some additional costs. 🙁
  • First-boot of this robot was an issue, due to cost down. The official Jetson Nano is replaced with a nockoff, which did not boot from SD. Together with the DuckieTeam it was resolved..
  • Calibration of all sensors went straight forwards.
    Although using live CAM feed, a different browser is needed.
  • Issue: driving straight (on one tile) is impossible. Somehow this robot turns 90 degrees on one tile, while driving ‘forwards’…
    What is going on?
  • The MOOC 2025 – April edition is moved to July 31…

Other hardware

I decided to create the road-tiles & the traffic signs (optional?) myselfs.

After adding some tape & cutting:

So, that looks like a nice result. I should have bought at least 13 tiles, for driving that 8-figure… And definately need some more signs, looking to the potential hazards down the road.

The 2022 MOOC

I did enroll the 2022 MOOC version before, but never installed any software. Let’s continue debugging/running the DB21J…
