- FLL team Automaticus Rex scores 370 points using the new "push-up" drive train. After winning the Colorado state champion, Automaticus Rex went on to win 2nd place Design and Innovation Award at the Houston World Festival.
I remember, last year, seeing you dominate the field and the state qualifier. We were there when you guys made it to worlds. It was a lot to look up to. Now, this year, we're in your place. We're being sent off to worlds with no idea what it will be like. Good job, I think your stuff was awesome.
were putting a Colorado flag on one of this year's attachments too.
A couple of our members were at State and saw your robot. We were blown away! Best of luck at worlds, you guys have a world class robot and I'm sure you will make it even better!
Family Gedney thanks so much! 😁
1:11 That's awesome!! Will you guys partecipate in this season?
Unfortunately, no.
Real cool! Super innovative ideas here! Innovation award! Can u make another video about your base robot? I don't quite understand how it works. Why does it need to lift part of itself up to turn? Is there not a simpler way?
Also do u use another motor to lift part of the robot up when u turn?
This design uses only two motors for navigation; one for lifting, the other for driving and turning.
We will soon release a video that goes into our base design in more detail. In short, most teams use “tank” drive, which means the robot has two driven wheels, one on each side, each independently powered by a motor. These two motors are hard to synchronize, causing curving when attempting to go straight and wheel slippage when attempting to make turns. To avoid this some teams use sensors but the gyro sensor stinks and there are little to no lines on FLL mats. So we designed a completely new drive train, called “push-up drive”. Push up drive can be in two modes: either driving forwards and backwards or turning. Both of these modes are driven by the same motor. The mode for driving forwards and backwards has a minimum of 6 wheels on the ground and a very long base. With this setup, our robot drives very accurately in a straight line. For the turning mode a second motor lifts the robot like a second class lever, lowering the 3 lateral wheels. The lateral wheels lift the wheels that drive forwards and backwards off the ground which enables our robot to turn about a single axis with great accuracy ( you can see this in 3:04). You might have noticed built our robot does not use sensors for navigation but is still the most accurate robot we have ever built.

Family Gedney - nice! That is very smart! Never thought of using something like push-up drive! Is it really that accurate and consistent? The only downside seems to be the time it takes to push up.
When you are driving out on the platform base, how do you place the wheels so that they don't rub on the base? Also, how do you keep the platform base from backing up when you reverse the wheel direction? Third, what gears do you use to transfer the movement to the platform base? Thanks, and great robot!
Teams that use a platform always surprise me; Untitled_1, Ctrl+Z, and even you guys! I've always seen various teams use a platform in their massive attachments, but I've never known how they actually work, would you mind explaining it to me?
