Just wondering, how effective is a robot like this in competition? I personally am a 2 mogo ring bot like a lot of teams, but we dont have a lot of successful 3-4 mogo park bots over here as far as I have seen (SoCal). They do pretty well in qualification matches, but not as well in elimination matches. Great robot overall and good luck in the rest of the season.

I like the idea of using a holonomic drive to make use of the sides of a robot for more goal capacity.

I really wish I did do something like this as it would have been very fun to do

We are very effective when paired up with a robot that goes for more rings

We just got the pneumatics, so I don’t know how much better it will be In a competition. We do have one this Saturday, so I will hopefully have some videos to share of it in action

Good luck this weekend! We will also be competing and will hopefully be able to help our sister team to a qual.

looks interesting! Would you be willing to explain how the claw folds out?

The claw is just a triangle with each of the corners being able to rotate, and one of the sides being able to expand with the pneumatic cylinder, when the claw unfolds completely, the screw and c-channel lock together so that it can’t bend back again.
(We took apart the robot recently to make a more ring centered robot so I can’t provide a video :frowning: )

Your robot looks very interesting!

But, I have a question. What made you want to use a mecanum wheel drivetrain rather than omnis or traction wheels?

My guess would be that they used mecanums so that they could strafe and pick up goals from the side.

Because they can pick up mobile goals from both the front/back and the sides of their robot, having a holonomic drivetrain allows them to easily intake mobile goals from any side of their robot. Without it, they would have a hard time intaking mogos via their side intakes.

We say that It is so that we can grab things from the side, but secretly it is because we just got the mecanum wheels, and I wanted to use them for programming and because they look cool.

Sadly we did just take apart the robot for a more ring focused robot, here is a video I got of a match we were in.

(The auton didn’t fully work, and our driver wasn’t very good, but if you are looking for a MOGO focused robot, I would recommend this)

That is the third competition we have been to where that happened (the other two were caused two years ago by TT tray bots). It sure caught everyone off guard.
