We're working with Halifax Solid Waste Management Services to build an educational robot out of recycled materials.

Project started 2018-05-29. Discussion is on our Google Group.


Build an educational robot that could be taken to Halifax schools to help educators teach children about recycling.


  • Airline carry-on size 22 cm x 35 cm x 56 cm (max)
  • Constructed primarily from post-consumer recycled materials
  • Friendly
  • Able to play pre-recorded audio clips (typically containing speech)
  • Audio clips cued by remote control
  • Capable of limited motion (i.e. not just a talking statue)

Proposed Stretch Goals:

  • Animated face (possibly NeoPixel, DotStar, or Hub75 panel behind a diffuser of some kind)
  • Additional motion
  • Voice recognition

We are targeting the 2018-2019 school year, but the project may continue to evolve beyond that.

Techniques, components, resources

Recycling plastic

Be careful about the carcinogenic(?) fumes!

Local company that may have cutoffs for us to reuse, skipping the melting and extrusion step for us:

The brains

Raspberry pi is the way to go, we think. Power: A decent sized USB powerbank can deliver 5 watts for 4 hours. A Pi with accessories needs about 5 watts? Need to check this guess…
