I love it! I hope he's under 120 pounds!
Also, where is the mini robot going ?

But all kidding aside, I love the idea of putting somebody on the moving chasis! Hope to see a real robot version !

[Nemisis]

hey man i just watched your video and i have a small question? Where exactly do you bolt the human on? lol jk however i must say if you and your team designs it and it successfully works that's awesome!

[Prontopwnage]

Good stuff Nice arm idea, You might want to have some type of system to channel the tubes onto your grabber a little better. But this is a great first example

[rcmolloy]

Just a few questions...

1. Would the GDC approve of the green energy ATP-usage machines to power the robot?

2. What if the lifting mechanism springs a leak in their system?

I'm curious about the response.

First of all, tell the guy pushing to bend his legs; he would generate more force that way. Other than that, what would be "doing" the closing? Would it be a motor or a pneumatic actuator?

[merazjesus842]

Our team is not using any pneumatics this year so the arm mechanism will be run by a motor.Also later on we will post CAD drawings of the arm on our website. http://falconroboticsteam842.org/default.aspx

I like it! is there any special coating/material on the bars that grip the tube? or does geometry make it work?

[synth3tk]

What's the song name? It sounds familiar, but I can't place my finger on it.

Also, that's a really unique concept. How did you guys come up with the idea?

[Daniel Krastev]

<R14> When a ROBOT is in its STARTING CONFIGURATION, no part of the ROBOT shall extend outside the vertical projection of the FRAME PERIMETER.

How are you going to configure your manipulator such that it doesn't extend past the front C-Channel before the start of the match?

That's a whole separate problem to work with...I think that rule ruins a lot of peoples' days

As I recall it sprouted from a discussion about last year's pinching mechanisms. We were talking about the benefits of a wide grabber and this concept emerged.

We think we have that part figured out as well. As a matter of fact, I think the manipulator we're considering at the moment would stay in the 60" cylinder with this gripper attached. Here's a hint as to the approach we're taking.

That's 84 inches now....

[dtengineering]

If only there had been a three-year old sitting on the back of the robot until the last ten seconds of the test.....

The beauty of this post isn't just that it shows an idea for a gripper that might help inspire teams, but that it shows a great way of prototyping a concept. We've built all sorts of mock ups over the years, but never thought to do it this way!

Brilliant!

prototyping at it's finest.

Right now there is currently double sided tape on the bars but we are planning on using this cell phone cover material that is sticky but not sticky. I am not really sure how to explain it.
