The Kepler Electronics Guide to the DR4B 

Fam some of your tips have been very useful to me, keep those uploads going! Gj

Is it me or does he sound like MatPat from Game Theory...

1:27 Note to viewers: The two c-channels are not both attached to the gear.

Great content, thank you and keep it coming!

Love the video!! It was explained so well! Thanks :)

hey mate, thank you so much, im using screw joints instead of axle joints, but this helps an ungodly amount, my bot last year had no bearings no nothing, it was all steel and uber jank, but I'm trying to make an op worlds bot for this years game (tipping point) and your guides actually helped so much (even tho I'm a junior) Thanks again - team 8471

Parts needed for one side of an usagi-inspired dr4b: One section = 5 holes 2 x 7-section c-channel (the top 4-bar of the lift, will be attached to gear) 2 x 6-section c-channel (the bottom 4-bar of the lift, will be attached to a gear) 2 x 4-section c-channel (brackets the two 4-bars, and ensures the gears mesh) 1 x 3-section c-channel (attaches the top 4-bar and actual operational mechanism used to play the game) 1 x 5-section c-channel (attaches to bottom 4-bar and main robot) 2 thick gears, size does not matter, as long as they aren't thin lots of axles, bearing flats, small screws and nuts and lots of spacers of various sizes it may be better to prototype it first with janky screw joints and then replace those with spaced out axles one-by-one once the minimum viable product is complete.

Are u going to worlds this year?

I was the thousandth sub :D

owh ! what are these giant mecano perfored metal profile ?

Awesome tutorial! Out of curiosity because our robotics team is recreating this lift, how tall can this lift get? We’re considering adding a six bar at the top but if it’s unnecessary we save parts not doing that.

what does the instrument refer to?

OMG ITS MINI MATPAT

1:37 how did you connect the second piece? because the screws and the holes dont line up

Great guide, but it should be noted that screw joints are amazing compared to axle joints, and should be used whenever possible

Screw joints op. And 1m dr4b

yeet

this man sounds like matpat from game/film theory

Who’s here for High Stakes?

idk why people have trouble with this, it’s literally just two four bars

Now make a knock off Boston dynamics with me lol

Where is the like button at. I liked the video but could not find the like button. Help.

HALLLP... we can't find code for the lift. HALP USSSSSSSSSSSS!!

it went way too fast i couldn’t keep up

GO SLOWER AND TAKE US THRU THE STEPS

69 dude

this is a good guide for beginners but there are a lot of things you change to make it lighter and more durable. but, overall nice job! i'm the builder on my team and our jankbot ended up being one of the top bots in our state. i'd love to add my input for any of your building videos.
