Re: 1351 Launches a Trackball
I smell gas struts............. they are evil. We used 120lbs ones last year and we used a drill and a device we made to shut them and we killed our drill and our device. But i guess you guys would only have to use like 20lbs-40lbs max.

Re: 1351 Launches a Trackball
Nope, purely springs. We were thinking gas springs originally, but decided they were too slow.
In fact, 20 or so minutes ago, we launched it with the final springs (we got em yesterday!) and we got more then 10 feet of height:eek:! It was crazy. Ill see about YouTubing that video. |
Re: 1351 Launches a Trackball
The 10 feet was insane. The whole campus could hear us cheer. We might youtube the vid later in the build.
But seriously folks, this thing we've build is extremely dangerous. We need blinking warning lights or something. I have no doubts that this device could break bone. All other teams who are using a launcher - be very careful. (Refer to the FIRST update too) Sam |
Re: 1351 Launches a Trackball
How on Earth do you guys keep your trackball so red???
Do you apply a fresh coat of paint to it everyday??? |

Nice job about thinking of safety. From the video that was posted it looked like everyone was standing in a safe area. One more thing, The video you posted got pretty high up but only moved about 1 or 2 feet away from the robot. Do your new springs fix that, or are you working on getting more distance, or do you just not want anymore distance? Joey |
Re: 1351 Launches a Trackball
We do out best to only use cameras with crappy compression so the entire ball comes out to a nice juicy red. :D
It is still going mostly vertical. The theory goes that we will be able to move the robot to add velocity in the X, so we may as well put most of the energy into the Y. The more Y we get, the slower the robot can move. Added bonus, if we're REALLY lucky, we might be able to drop the trackball ontop of the rack with a mostly vertical shooter. But probably not. ;) |
Re: 1351 Launches a Trackball
What kind of safety features are you considering now that you have a device which "can break bone". Our catapult has 3 interlocks and we are looking at more. How do you plan on slowly releasing the energy on power down?
