I really enjoyed putting this little critter together. I like to drive it down the hall in the morning and deliver coffee etc to family members - secured on a carrier bracket I made and bolted to it's back. Loads of fun. I'll be monkeying around with this creature over the winter, finding new ways to use it and new functions and components to program.
I had a minor issue with the ultrasonic "eyes" and, after walking me through some troubleshooting, Elegoo quickly sent a replacement board that solved the problem.
