First off, that is hilarious.

Second, are you worried about incidental contact inside the bumper zone with a robot that drives up behind you? I presume the hammer moves fairly quickly.

Re: pic: 3313 Towers and Grippers Mounted
 

Does that break 20" outside of your frame when the hammer swings through? looks close.

Re: pic: 3313 Towers and Grippers Mounted
 

I do not see that cantilevered shaft holding up for long.

Re: pic: 3313 Towers and Grippers Mounted
 

I love it! The Ban Hammer!

Re: pic: 3313 Towers and Grippers Mounted
 

If this robot is not named Thor I will be sorely disappointed.

Re: pic: 3313 Towers and Grippers Mounted
 

Or John Henry.

Re: pic: 3313 Towers and Grippers Mounted
 

Mjolnir

Re: pic: 3313 Towers and Grippers Mounted
 

THOR IS OLD

JOHN HENRY FOR SURE

Re: pic: 3313 Towers and Grippers Mounted
 

RC Hammer?

Re: pic: 3313 Towers and Grippers Mounted
 

Stop!

Hammer time.

Re: pic: 3313 Towers and Grippers Mounted
 

Funny, that's what I said when they first showed a picture of the hammer!

I also think that the cantilevered shaft is going to be an issue... the torque from impacting the ball is going to be significant, I think.

You had a snow day so you got to work MORE???
Lucky dogs. We are not allowed in the school on snow days.

Re: pic: 3313 Towers and Grippers Mounted
 

Same, today is our 4th snow day of the build season.

Re: pic: 3313 Towers and Grippers Mounted
 

*Ding Ding Ding* We have a winner.

Re: pic: 3313 Towers and Grippers Mounted
 

Does your Kicking Hammer hit the ball on the bottom or near the back of it?

Re: pic: 3313 Towers and Grippers Mounted
 

Holy smokes! So many replies!!

The cantilevered hex hub shaft... We have some plans for the hex hub shaft that the hammer mounts on. We are either going to mount the shaft to a bearing on a plate (from the other tower) or we are going to extend the shaft with a set screw and some other stuff. At any rate... We have plans! I'm bad at explaining these things. Haha.

It does not stick outside of the 20". The hammer (from the shaft down) is about 24" and the shaft is mounted about 10" in. Soooo, we're ok on that end.

The hammer will be able to strike the ball either directly underneath it (for a truss shot) or closer to the back (for a goal shot). The grippers in the front can bring the ball up or down.

We plan to name it Thor. When we make our reveal video and finish detailing it, you'll see why.

However, RC Hammer is insanely awesome. And John Henry.

Re: pic: 3313 Towers and Grippers Mounted
 

next time when you build a tall superstructure like that add some bends to the long flanges to make the part stiffer. Think triangle support.

Re: pic: 3313 Towers and Grippers Mounted
 

Is that solid steel on the hammer head? It looks tough! However, that tiny ridge makes me think it may just be plastic! Also, are you using shifters? What is your robot's range with this?

Re: pic: 3313 Towers and Grippers Mounted
 

Hammer First Trial YouTube Video

Here's a video of the hammer and grippers in action. Obvious disclaimer that this was literally the first time we ever kicked a ball with our final parts.

Also, we plan to do a ton of refining and the hammer isn't even mounted on there correctly. It's still just sitting on that one hex shaft out of the toughbox. We will correct that in the future.

We are just impatient and want to kick a freaking ball. Haha.

Re: pic: 3313 Towers and Grippers Mounted
 

Can't wait to see you guys up in Duluth and at the Twin Cities regionals-- we aren't competing, but I hope we'll get the chance to at Champs and MN State. It's been a lot of fun watching your videos and reading your blog posts over the last few weeks.

Re: pic: 3313 Towers and Grippers Mounted
 

Looks like painted wood to me.

Re: pic: 3313 Towers and Grippers Mounted
 

Maxwell's Silver Hammer? Maybe just for the name of the mechanism? Pleeeaseeeee:D

Re: pic: 3313 Towers and Grippers Mounted
 

That was my vote. As well as Team 45 from the 2010(?) IRI Talent Show.

Re: pic: 3313 Towers and Grippers Mounted
 

I always love how nice and simple your robots are and am always jealous of how quickly you have a working robot. Too bad we dont get to compete together at duluth or the U. Good luck at competition hope to see you at State and Champs if both our teams manage to make it.

Re: pic: 3313 Towers and Grippers Mounted
 

Lucky for us (or possibly unlucky depending on if we are or aren't on their alliance), Team 2052 will be competing at both of 3313's regionals this year. I actually think 3313 is the only other team besides ourselves doing both of those regionals so it should be fun. I can't wait to see Thor in action!

Re: pic: 3313 Towers and Grippers Mounted
 

Can't speak for both, but it'll be a pleasure to see you all at lake superior!

Fear the hammer!

Re: pic: 3313 Towers and Grippers Mounted
 

But, you can still get called for contact inside an opponents bumper zone (which would be a brutal penalty and missed shot combination). Since you probably have some free time, I'd look into an extension within the bumper zone so opponents cannot get in the hammer's path.

Re: pic: 3313 Towers and Grippers Mounted
 

Ouch, yeah. Although I pity the robot that gets in the way of that hammer.
