Hi there,

Pretty scaring close up of the R3PTAR robot when ready to bite!
Pretty scaring close up of the R3PTAR when it’s ready to bite!

Here comes the R3PTAR (read Reptar), a slithering snake that can bite you! 🙂

If you are lucky enough to own the Lego Mindstorms Ev3 retail set, you surely know this one. The original building instructions from LEGO can be found here.

I’ve chosen to build and program the R3PTAR because I wanted to try to codify a mission:

  • Mission Phase 1: roam to find a victim (well actually, a victim improbably wearing the IR Beacon);
  • Mission Phase 2: chase the victim;
  • Mission Phase 3: when you’re close enough, give the victim three rapid bites.

And the R3PTAR must slither, of course!

Video, code and some technical notes will be posted soon! Stay tuned!
