Petoi Bittle X

by Petoi

#2 in Robot kits & armsBest for beginners

The kit I'd give a curious 10-year-old. You build this robot dog in about an hour, code it in blocks, Python or C++, and it obeys 35+ voice commands offline.

What’s good

  • Code in blocks, Python or C++
  • 35+ voice commands, processed offline
  • Free curriculum for classrooms

Heads-up

  • About 1 hour of walking per charge
  • AI chat needs a $39 add-on head
