Pi Wars – the Raspberry Pi robotics challenge competition

#TimeToRecharge DAY 15:
@CODECLUB: Final edits & parentmail release.
#PIWARS: Watched videos (Cranmere Code Club & Brian Corteil). Took notes. Researched motors & controllers.
@recantha @Geeky_Tim too big to enter into #PiWars?
OMG! Why has no one ever told me that such things exist
@MolloyLaurence Yeah, I'm using @4xR10 twitter account for #PiWars. I fairly busy going to shows at the moment but it would be good to meet up. Maybe this weekend or next week?
@recantha Okay... sounds like a £15-£20 @4tronix_uk Zero or @Pi_Borg Zero might be the way to go then... but nonetheless curious about the details of that CamJam controller - from your experience, Mike, have they been reliable little beasties in a #PiWars setting?
@MolloyLaurence They're fine if the stall current of the motor attached to them isn't too high. Inefficient, but for #PiWars this isn't really an issue (the motor controllers I used were at the other extreme and featured energy harvesting under braking, but really just buy more batteries!)
#PiWars tweeps... is there any reason why an L298N is bad for competition bots (other than energy wastage implied by massive heatsink). It's a lot cheaper than more popular controller boards.
@approx_eng Cost, speed, convenience. I got a cheap Tronxy X1, its great for iterative design. Had I sent all the revisions I did to Shapeways, I would be now be selling my house to pay for it, and would not have had a robot for #PiWars.
Check out .@Vishal_dhayalan’s Blog. Really neat and helpful posts there for everything #PiWars!

@MolloyLaurence @recantha Yes be fine, my standard design works that way both with the Tiny 4WD and the MAX chassis, my last two #PiWars robots used 4WD with 2 channel drivers
@TheMagPi Nothing earth shattering, but I did build an STS-Pi with my 10 year old as an early #PiWars test platform.
Today I am performing a motor controller comparison for all of last year's most popular boards so we can decide which controller our team will use.
