What The Duck(ling)

Bot Builds & Designs

Greetings all!

I thought to start a build log for my 150g in progress bot, What The Duck(ling). It is a overhead drill cam lifter with interchangeable weapons including, but not limited to, an axe, flipper, and grabber.

It was mainly inspired by Auger The Top and The Power Of Friendship. I wanted to finally make a damaging bot and this was my solution. I also wanted the abilities of a cam lifter.

It’s currently in the prototyping phase with some rough chassis printed and the mechnisms somewhat figured out. For the drill bit I replaced the shaft of an 1806 motor. I also had to massively downsize the servos used for the forks compared to my previous cam lifter, Guido. For driving the arm I’m using a prototype M10 from Ranglebox which should be lighter but just as strong.

This is the most recent prototype:

Currently the prototype chassis is printed out of PLA but the final print will be TPU.

Any feedback or ideas would be greatly appreciated! :smiley:

Great looking design! A drill can be suprisingly effective at 150g.
I’m a little dubious of that small all plastic servo though, I think its likely to strip teeth in the harsh life of a combat robot. Perhaps you can strip some weight out of the frame and upgrade it?

I’m hopeful about the servo as a cam lifter requires very little torque and I shouldn’t reach their stall torque. I would only be worried about a direct hit from verts (I’ll have arour for horizontals but not much I can do for verts). I’ve ordered some BECs from BBB so I should be able to test today.
