Re: pic: Teaser manipulator
Nice!!! but the real question did it work well? Because We had a similar idea to it.

Re: pic: Teaser manipulator
For concrete jersey barriers?

Re: pic: Teaser manipulator
I would be carful with that getting ripped off your robot during collection.
When building a ground-picker-upper ask yourself would this break if a robot hit it square on going 10fps? |

Is that some type of urethane tubing you are using? If so, how did you weld/join yours together, they look nice and neat.

Re: pic: Teaser manipulator
The orange cord is called polycord you can order it from Mcmaster-carr, it is joined by heating the material up, joining it, then letting it mold together and cool. Works really good for a variety of FRC and other applications.

Re: pic: Teaser manipulator
This looks really HEAVY. Whats it weigh in at?
|
Re: pic: Teaser manipulator
I agree with sean it looks really heavy ,but if you are able to lighten it i think it will be very useful for manipulating the tube.

If you mounted the larger pulleys concentrically with the pivot for the corresponding 'finger' the belts would maintain tension as the grabber opens and closes.

Re: pic: Teaser manipulator
It weighs in less than 5 lbs and the reason for the offset of the drive pulleys is so we can tension it. The arms wont move during the game.

This entire thread is very helpful when it comes to polycord. |
Re: pic: Teaser manipulator
I think the concept is good but it could be cleaned up a bit...
is this just a prototype? HINT: the tube surface is very different than in 07 and I believe that wheels work better than belts. Also in a collision belts may come loose easier than wheels... |

@jblay
I'll have to give your method a try. Trying to force to ends together by hand with a heat gun or soldering iron is a pretty poor way to join polycord, as it is apparently called. |

Looks great Guys! who did your welding?:yikes:
|
Re: pic: Teaser manipulator
Students actually weld everything on the robot; some welds look great, and others, well its 18 year olds welding... We are proud of what comes out of our shop purely because it was all made by the hands of teenagers. We have nothing machined.
