STEM project ideas
This is a page for STEM project ideas, things we can do as workshops or at events like MayFest, TechFest, IET open doors day and such like.
This is a place for everything from raw ideas to completed projects.
It was created after a mailing list thread, see http://lists.57north.co/pipermail/57north-ctte/2019-February/000240.html
See also, the Projects page for a general list of projects.
Kind of unrelated, you can become a STEM ambassador, via https://www.stem.org.uk/stem-ambassadors
Usually led by User:Nordin we have a bunch of parts for this.
Typical arrangements (as per last run)
Make sure the brushbot box is stocked with:
- Coin cell batteries tucked inside shrink wrap
- Vibromoters soldered to 3 pins of a 3x2 section of double-row pinheader that are glued to the motor, wrapped in a heat-shrinked package
- Assorted long-legged LEDs (Flashing if possible)
- Toothbrushes, stalk cut short (ASDA is a good source)
- Glue dots and double-sided sticky pads (Poundland is a good source)
- An assortment of googley eyes, pipe-cleaners, paperclips, feathers, clips etc (Also Poundland)
The idea behind the workshop is allow attendants to observe first hand the trade-offs when designing robots, the iterative nature of trail-and-error learning, and the usefulness of combining ideas of others, including team opponents. Emphasis is made on how a thoughtful design is key, especially given the fact that the bots effectively move randomly.
How it's ran
- Attendants are split into groups which are paired with one another group e.g. 12 attendants split into 4 teams of 3 (ABCD) with teams paired into team-groups (AB, CD) with a judge per team-group.
- Team-groups are given coin-toss, the winning team choses between one of two types of brushbot: Capturebot or Escapebot. The team losing the toss is assigned the remainder.
- The teams have 10mins to build their assigned bot.
- The bots are then placed into an enclosed area (ideally round) and battle commences between team-groups teams (AvB, CvD). This can be in multiple rounds as deemed by the judge.
- Successive rounds of redesign and battle take place, points are awarded out of 10 by an impartal judge on role effectiveness and aesthetics.
- After both team-groups have declared winners, the teams merge with their team-group counterpart and a coin toss for bot selection is made as before. The designs are tweaked further over a final 10min design period and a final battle takes place. (AB v CD).
Idea by User:Nordin "Basically using those small sG90 servos and a brush on each side. When not vibrating for forward/backward motion, the servo's are also little arms that can poke stuff." - Ed

"the nerf targets were a great fit for us - they combined some great technology and science with a really fun activity." - Thomas at ASC.
Air Quality Monitor
Perhaps a bit more advanced, but just adding here for completeness. See Projects:Air_Quality_Monitor.
It's not a great STEM project, as far as learning goes, but it can be good for drawing attention to a stand as it's kinda fun. See https://retropie.org.uk/ and User:Andyg has the (minimal amount of) hardware needed. See Projects:RetroPi.
Just other ideas, early stage.
