the RO bots
After a long(er) winter break, and somewhat continuous shopping spree – for components and especially for small robots or chassis able to compete in PiWars 2020, we are back blogging – eager to show you some of our [past] contenders, and especially their pro’s and con’s.
While it would have been really nice for us/me[?] to 3D design and print our robot’s body or chassis – as we’re qualified in the Beginner branch of PiWars – we are under no pressure to out-compete other beginners. We’re going there for the fun of it, plus as a team/family experience.
As you may imagine, over the past 3 months, our envisioned or possible robot designs, off-the-shelf options, plus their initial testing has made us change our minds about the perfect PiWars 2020 competition robot many times over.
Here’s a very short summary of (y)our options from 2019, as 2020 has just started.
From the cheapest, to the fastest, to the more extensible, to the most expensive.
- CamJam EduKit #3 robot at £18 (hard carton chassis, requires some drilling)
- STS-Pi roving robot at £22.50 (its caster ball’s arm looks really soft)
- Coretec 4WD robot at £54.90, plus fastest motors at £24 (fast as a 🚀)
- Pi2Go Mk2 4WD robot at £83.40 (yellow TT motors capped at 240 RPM)
- PiCar-S robot at €90 (also based on yellow TT motors; max RPM ~240 as well)
- Sphero RVR robot at $249 (expensive, but most promising, hackable, and speedy)
- DJI RoboMaster S1 robot at €549 (despite its price, has an immature Python SDK)
P.S. DJI’s RoboMaster S1 is just FYI as it exceeds the PiWars competition max. chassis dimensions by 25mm (in length)
