So BotFest was due to happen a few months ago, but was unfortunately cancelled due to lockdown. I had redesigned Crumbs! to improve the lifter as the servo driven one didn't have enough power.

I always wanted to build a 4-bar lifter but kept it under wraps until the event. When it was cancelled, I lost a lot of motivation to work on it and it sat in my Fusion360 files for a few months, until last weekend!



The arm is now powered by a 100rpm N20 rather than a servo, plus a 300mAh 2S battery.

It needs reprinting at a thinner layer thickness before it is truly combat ready, plus superglueing a stainless steel beak (leftover from BDR) to the front arm. Regardless, I'm super happy with it.

Hopefully events get back to normal sooner rather than later so I can take it for a proper test run!
