Very nice overall.
We've not abandoned all hope to have a ringer scoring implement, but it's been a secondary priority since day one and so it's been treated as such. We've prototyped manipulators and designed arms, but our push is to do everything we can to first ensure that our lifts are working as well as they possibly can. If after that we have the time and resources to think about adding the arm, we'll do so.

Can you shed some light onto what the two small protrusions at the bottom (picture-wise, top right) of the robot are? They look almost like tower supports, but in the bottom right head-on view, there's no tower. Can you describe what they are?
Those are Fisher Price motors coupled to the 42mm BaneBots 256:1 gearboxes. They drive the rotation of the lift mechanisms. The arm, should it be added to the robot, sits in the space between each of those motors.

It's interesting to me that for a (I assume) defensive robot you chose the omnis with powered middle wheels. From what I've heard, you could get turned around your axis pretty easily. Did you choose to put two motors to each side to counteract it?
If we end up acting as a defensive robot, we're prepared to replace two of the omniwheels with a second set of the kitbot wheels for some added resistance to rotation. Our gearboxes are geared lower than kitbot drivetrains and a second motor gives us some extra torque at reasonable speed, so we feel pretty comfortable that our drive is powerful enough to prevent many teams from scoring.

Nice design overall.
Thanks.
