Showroom Cheap 2DOF proyect

Hi!

No way! I don't have a lot of time to dedicate to the project. But this especially long weekend in Spain I'm going to try to make the base, the levers, the cardan and with a bit of luck connect only one motor, since I am missing two ball joints, which are quite expensive!
As for the levers, I'm going to try to heat them up and make them red hot, then I'll try to tighten with the nut to see if the teeth of the motor shaft are marked on the lever, but I don't have much hope on that.

Some pics about yesterday work.

Sunday! I have finish the rig, i'm not sure if i'm going to do a rig for the legs, i'm thinking on it.

Cheers!

Some more pics.

I would like to use gears with the pots but in the first stage i will use direct drive.

This week we will find out if the engines are capable of lifting the structure and hopefully my weight. Bets accepted !!! ;-)

This afthernoom i will finish the wiring and test.

Thanks!

I'm on the way! but i think tests wont be possible this afthernoom. I have buy a screw shield, but i had to solder the pins before use, and it have been a waste of time. I have buy new pots, wires and connectors.

Man at work!!!

Hello ! In terms of mechanic (dynamics to be more precise) I think too that long lever will be a problem ! Just the additive mass of the lever can be a disadvantage. because the torque of the motor is the same for small or long lever, and with the long arm you have a big lever-arm effect (because lever is long) So it will carry smaller mass. So to resume, the mass of the rig will create a big lever-arm effect on the lever, that the torque motor can't handle. So i recommand you to make them shorter (or you have to put stronger motor to have such a big range of movement !

Some good news! Today we are going to see movement on rig!!!

Now testting TRINUS PSVR, looks great!

Hi!

Thinking on buying a better photos, with hall sensor do you recomindme?

What do you think about this one :

Hello friends!

I'm organizing the wiring a bit. I have installed a second power supply, one per motor with separate power. I have installed some rectifier bridges so that the power supply does not turn off with the feedback.
Well, the mechanics and electronics thing is going well, but I am a mess with the axis assignment.
I want to feel the acceleration, braking and lateral forces but the more laps I give the more confused I am. A little help would be appreciated.
Cheers

Hello friends,

I apologize for the time I have been absent, but I have never stopped thinking about the project, hehe

I have designed a 3d potentiomer housing to install a hall sensor and place some magnets.
I feel like the gap for the magnets is too big, but I did it for the ones I had on hand.
With my printer I can't get enough hardness and the shaft breaks easily, so I have abandoned the 3d option and bought some sensors in china.
