Throttle Motor

[SciBorg Dave]

Has anyone used Throttle Motor Denso AE235100-0160 on their robot ? If you have what function did you use this motor for ?
Thanks VIKotic/ SciBorg Dave

In 2012, 469 coupled it to a small leadscrew to tilt the shooter up and down.

For what it's worth, every inspector we had that year told it was the first time they'd seen someone use it on their robot.

Well that was the first year it was legal

We always think about it, and then realize there are much better motors that are much easier to use. The power pins on the front require some really interesting configurations to get working. In addition, there are no COTS gearboxes that work with them.

A gear box for this motor maybe a good project for some team.

Why would a team waste time finding a way to gear down an 18W motor when there are a plethora of better options available? There are equally compact motors that interface much more cleanly and provide much more power. Further still, if you have a low power, low speed application, the window motor already provides an option without additional external gearing.

I see no reason to use the throttle motor, personally.

I have not seen this motor used on any robot. I like the motor and am trying to find a good use for it.

Didn't 1640 use it for doing speed feedback on their shooter some year too?

[Gdeaver]

Yes, 1640 did use it as a tachometer for the ball shooter. That year our programmers were stretched on other things and there was not time for them to get up to speed on quadrature and PIDS. So we attached the throttle motor to the shaft and ran it in to a rc filter. They had an analog voltage from o to 8 volts. What the programming team did from there I don't remember. It worked. Since then the programming team has learned to deal with encoders.

4678 used one this year with 3D printed gears and gearbox. If I remember correctly they managed to print a gear that matches the pinion permanently attached to the motor. Maybe one of their members could chime in and provide more info.

[Jon Stratis]

We had worked out a way to couple it to an existing PG gearbox from AndyMark to use as a steering motor for a swerve drive. We prototyped the coupler and knew that would work, but we never got around to building it into a swerve drive and testing that part out. Our driver for that was the fact that we could use 4 of them and had no place else we would want to use them - if they would work there, it would be great. Of course, just as we were about to start testing it, FIRST started allowing more and more motors... So, that project was shelved, as there are better and easier motors to use for that now that we don't have to worry about quantity. Of course, that could all change again...

Yes, we did use one on our Recycle Rush robot at the IRI. We added the ability to pick up the 3rd can in order to manage a 28 point autonomous. The throttle motor drives a 3D printed sprocket on a hex shaft with a 10-turn pot mounted on the other end. We had fairly strong string wrap around the hex shaft and it had no problem lifting the can off the ground in less than 2 seconds. We did a 28 point autonomous a couple of times (see match Q4 of the 2015 IRI) The lifting mechanism was strong enough to lift the can right up sideways and bust the string (Q73) when our autonomous didn't complete properly. This messed us up big time and we scored 0 points for our alliance that round. Anyways, the throttle motor can certainly work and using a 3D printed gear to get a 15:1 gear ratio worked very well. I'm pretty sure the gear was strong enough to stall the motor without breaking teeth. You can see the 3D image here. http://www.cybercavs.com/throttle-motor.html

We have bags full of them that we rarely if ever use. The only occasion I can think of when we used one was in 2013 to pull a pin on a spring-loaded flap that was too tall to start the match open so we pulled the pin in auton and it stayed open for the rest of the match. When we did that, we used it with a gearbox like the one shown in the picture below.

So it is the power source on the window motor ?

The window motor is a different (but very similar) motor.

Hi I am a member of team 4613 Barker Redbacks, we have designed a low cost, low part count gearbox which gives the motor a 7.5:1 gear reduction, with a ½ hex output shaft. Our team has the capacity to manufacture these gearboxes in-house and we have partnered with a local sponsor. We are going to donate 40 of these gearbox kits to rookie teams in countries where it can be difficult to get parts like Australia, Brazil, Turkey and China among others. We will also spread the project to the FRC community by encouraging teams who have access to similar machining resources and distribute the gearboxes to teams in their area.

We have been in contact with Frank and he has confirmed that the throttle motor will be legal and sent out in the KOP once again in 2016(but with the FirstChoice release, we already knew this)

We have already made several systems utilising the gearbox we have designed, including a Polycord intake.

More information about the project will soon be on our website: www.team4613.org
