FRC Blog - FIRST Choice 2015 has Launched

This is a reminder that FIRST Choice opened for window shopping at 12:00 pm (noon) Eastern Time (this FRC blog described the soft opening in detail in October). Your team’s login information will be available on your Team Summary page in TIMS, and your team is now able to start constructing your Priority Lists.

Each team that has registered and secured payment with a Purchase Order, Payment, or Letter of Commitment from a Sponsor will be issued 600 credits. Don’t forget that Priority Lists must be submitted to AndyMark by Wednesday, 12/3 at 12:00 pm (noon) Eastern Time. Please keep in mind that with the new process, everyone who submits their list by the deadline will have an equal opportunity at FIRST Choice items. There is no advantage to submitting your list early, so take your time, but be sure to get your list in by the deadline!

Some items didn’t make the inventory delivery deadline, so we will likely add additional items for Kickoff. If we do so, we will add additional credits to each team’s account. We will use the same priority list process and announce the exact dates and times as soon as we know them. We understand that it is likely frustrating to not see all inventory that may be available to you, but we’d rather make this inventory available to teams this season instead of holding it for next season. Credits that are not used in the first round of priority lists or open orders will be rolled over for the second round.

Have you seen the bosch motor? It looks new

The seat motor? Nice throwback.

For all you younguns, there were seat motors in the KOP before my time (I haven't seen one come in the KOP since '03, but they were in it in '02). It's only recently been legal to use 'em again (ARA donation), and this one looks like a nice one.


Anybody looking for a hint, these things are really good for weight transfer if you need to do that. That's one of the last uses I've seen for 'em, lifting 180 lb each and making it look easy. (2002 mobile goal, in case anybody's wondering.)

lifting the mobile goals into the air? Is there any reason this would be more potent than the window motor? Smaller form factor?

Any motor in the kit can lift 180 lbs and make it look easy... Most faster than this motor. The trick is gear reduction.

They were used in 02 bc high power motors were limited.

Also used because they had an attachment that drove a lead screw with a flexible shaft.

Don't remember a Bosch seat motor back then. Of course there was the drill motors and I think a van door.

This motor stalls at around 1000lbs in the push direction which would give you a good ~ 400lbs of working force if you want to use it in a safe range and not push the limits too much. Of course the price you pay is pretty high in that it's fairly slow. Perfect for precision positioning and maintaining position. This type of motor is used in seat lift and tilt applications as well as steering wheel and foot pedal adjustment.

Adapting to the right mechanism will help make up some speed. The nice advantage of this over let's say piecing together your own is it's ready to go with a hall sensor built in.

Some other good FRC applications:
- Positioning a shooter
- lifting a heavy weight and keeping it there when power is cut

I'm looking at this right now. Has anyone seen a motor curve? Only details I can find are on the spec sheet off FIRST Choice:

It would be cool to reacquaint these motors with the original seat lift mechanism i.e. simply buy the mechanism with the motor and replace the motor with the Andymark stamped motor. Does anyone have any idea of which seat lift mechanism it is?

That information should give you everything you need. Are you looking for some tolerances? Feel free to ask me any specific questions you may have about this motor and your application. I'll try to post a curve but it will basically be the information you've already seen in graphical format. I work for Bosch and helped implement this motor so can answer any technical questions you may have.

Motor was custom made and does not come directly out of any particular seat although very similar application can be found in many GM vehicles. Fairly easy to duplicate a similar mechanism. Providing the whole seat structure would probably push the weight limit. They're typically steel and built for crash robustness so may be overkill on the most part.
