great design, looks like a great range of motion for such a compact 6dof.

Love the small footprint.. Exactly what I should need!
As it looks likes a prototype for a 'product' I hope you want to elaborate more on your kit! Are you willing to share your design or used motor combo's.. perhaps a bit on pricing etc?! My room is too small for a large motor setup so using servos would be the best option I have..
Superb job and love to hear more on details!!!

Mobility is the real advantage in comparison to the other rigs. After use, you can easily roll the "heXpod" through 90 cm doors and store it wherever you want.

Can you tell what gearbox you used and where you did get this gearbox?! Still trying to figure out my needed budget!

there is a reseller for the teknic motors, but the quote they gave me was around $6250,- with gear and power supply but without shipping. I guess with taxes and other transport fees I would be looking towards the $9000,-
this is a bit, well a large bit out of my budget... Too bad as it would be the best solution for a small footprint.. Now starting search for another solution..

6 motors 350usd 2 power supply 440usd 6 gears 260usd
total:4500usd
Who is your Europe dealer and what kind of gear they have proposed? Anyway, can you go lower than 4500usd with inverter-motor-gear trio?

There wasn't a European dealer.. It was Motion Solutions in the US..
CPM-MCVC-3421S-RLN:The motors 299 *6 = 1794 SSt-EMF75:Powersupply teknic 522 *2 =1044 PEII070-020/CPM-MCVC-3421S-RL:Gearbox 496 *6 = 2980
+ cabling etc ..
Then I need it transported to Europe and than Tax, Custom duties etc.. The shipping of the powersuppy would be problematic because of the weight they told me (+/- 14kg each with packaging) proposed gearbox was 'Apex Dynamics Value Planetary Gearbox, Double Stage, 20:1 ratio, 9arc-min backlash '
Right No I am back to my 'traditional setup.. Motors and gear will be purchased in China.. and inverters I've found reasonable priced wj200's nearby.
For now I am sure lower than the $4500.. around 3000/3500 euro is my estimate for the inverter motor gear trio...
If I could find another solution for the gear and power I might be tempted to continue the servo route!!! Smaller footprint is what I really like!

"around 3000/3500 euro" yes thats about right including import and taxes etc, at least for the UK.
Actually if you stick with 0.75kw then you only need the Wj200-007sf which is quite a bit cheaper than the 015sf's i ordered so your estimate should easily cover it unless your country has crazy duties and taxes.

You have chosen the box yourself or it is a choice of an application engineer? I might be wrong but I am afraid that that gearbox do not match this motor. Apex gearbox for nema standard would be the AN Series. Even not sure if those could accept 12,7mm motor shaft. Anyway AC solution is cheeper and less risky. You will be able to deal with much more payload. cheers.

this was selected by the one I quoted this as I requested the motor with a reduction to +/- 30 rpm.. This is what they came with..
But you are right.. I better follow the 'safer' route and go for AC..

Another compact 6dof based on brilliant Thanos controller and Ian driver.

Thanks.
Great design! I like the removable support legs. Would you be happy to share your platform dimensions? Most people seem to have the levers inside and motors outwards, but I'm interested in building my platform with levers sticking outwards, to save space and make it more wife approvable:) All the best. Tino.

Most people seem to have the levers inside and motors outwards, but I'm interested in building my platform with levers sticking outwards, to save space and make it more wife approvable:) All the best. Tino. in most of the designs, the platform is smaller that the base. this is how you can get a descent angular motion range. by putting the levers outside you can reduce considerably the footprint but the platform will be more sensible to collisions, especially during combined movements. however if the waf factor is important to you, I would recommend first the 3d cad design, and a scaled mini model in order to solve the problems before starting to cut the metal.
Hexpod base diameter is around 89cm, which give you the width of 86cm. (your wife will be able to easily roll it through your apartment door, and let it fall in the stairs :-) the platform ratio of 0.80 was chosen in order to have a similar base/platform heim joint angel in the starting position.
also consider that in such a small design you will be on the edge with almost every parameter. gearbox radial load, joint limitations etc.
it is a gigantic puzzle when on every step a good compromise needs to be found. which makes actually a compact hexapod building fun.
I am looking forward to see your conception
good luck

Thank you for a quick reply! Good thing is that the simulator will be on the ground floor so no danger of stairs I've had a better look at your simulator and I've noticed that the motors are arranged in a star patter (hexagon) so might not work best with my motors and transmission. I'd like to have my motors arranged in a triangle pattern, like on this video: www.youtube.com/watch?v=uye-A-fUfdQJust not sure if I should have levers pointing outside of the triangle (like in the video) or pointing inwards like most AC 6dof simlators. I thought about welding the base, and I even got a cheap welding machine, but I've decided to make the base out of structural plywood. I'll be using Fanatec CSL seat (aluminium 12kg) so I won't have a lot of work to do on the top platform. I think I'll probably make a wooden model to test the dimension and movement, like Fabi did. What are your lever and rod lengths? P.S. I like the pc under the platform (I'll probably put a subwoofer) especially GTX Titan, it's a nice touch
