Gotta love these translations! Perhaps a decent value at 55% off, although it's likely to be a box of parts with (at best) Chinese instructions only, so not beginner-friendly. Looks small, maybe ~4" in diameter.

From http://www.icstation.com/robot-kits-robot-learn-kits-smart-turtle-wireless-arduino-p-2528.html

Smart little turtle is a single-chip learning application development system to arduino microcontroller family atmega-328p as the core, the completion of the hunt, obstacle avoidance, infrared remote control and Bluetooth remote control functions, the package contains a number of interesting programs, and can be extended outside the circuit module is set, thereby increasing the carriage of use. Designed to allow users to learn ARDUINO microcontroller off when dry theoretical knowledge in the play in the development of the ability to obtain SCM system.

2. Quality tires *2
3. motor mount *2
4. Bovine Wheels *1

  • Hah. It appears that this isn't a translation error, but an actual term. On aliexpress, you can buy a variety of them. They also call them "bovine eye wheels", which I guess does kinda describe their look.
  • Gotta love bad translation

    Ha, Seairth solves the mystery:

    I might have called them Steve Buscemi eyes.

    Oh, you mean Marty Feldman wheels:

    That's what I was thinking. :)

  • I'm just glad they decided against Total Recall Wheels.

    Almost snail-like!

    Gordon pointed out a funny observation about these "bovine wheels" AKA ball casters. They are designed to be used ball-up, for low-friction materials handling. Internally, they have lots of tiny bearing balls which are "recirculated" by gravity when they lose contact and fall back to the bottom where they are needed. Flip it over to use as a robot caster and all the balls fall away, so likely the top of the big ball is just resting/sliding on a steel part. Not very low friction that way, so on smooth surfaces the big ball may actually be sliding/skidding, not rolling. In that case you might as well glue a steel ball or glass marble (dirt cheap) in place to slide on. Too bad nobody sells half bearings or half marbles!

    You've got me there. All I can say is that those skidoos definitely have a big pair of bovine wheels!

    I've seen some interesting bovine orbs dangling from pickup truck trailer hitches.

    The Bovine wheel appears to be a "tail" wheel. ;-)

    Or is this just another of erco's tall tales?

    Mayhaps it's an udder failure.
