Lynxmotion Tech Support

We put the arm together, great fun, calibrated, it's working with RIOS. Great job Lynxmotion for making such a cool educational toy available for people.

I have two questions:

1) We have these parts left over, should we be concerned?


2) We have the RIOS software working with a joystick for the teachpendant mode. We tried a gamepad and a logitech 3d pro. I see how to assign axes the thing is we can't figure out how to reverse joystick input axes - the up/down (Y) is reversed if I assign it to the fwd/aft axis of the joystick in both cartesian task space and polar modes. If we can't reverse the input axes, can we send fake joystick commands via the socket interface (I looked at the protocol and only saw cmds for executing recorded motions). I know we can implement our own inverse kinematics and write to the SSC-32 ourselves, but RIOS is so nice, it would be awesome if the socket server accepted simulated joystick input commands or if the program allowed us to reverse input axes.

I saw a few people have already derived the inverse kinematics for this arm so that would be our next step if we can't reverse the axes in RIOS.

I know the PS2 controller is officially supported, does that mean if I use one then the Y axis will be correct - so that I can place the robot in a way that matches the simulation (say facing right) and then map the joystick axes to cartesian task space so fwd moves the end effector fwd, right moves it right, up moves it up? If so I'd buy one.

Thanks
Nick

The kits are packaged with components that may not be needed for your build. These parts are just extras for your parts bin.

We do not have a fully supported USB joystick for RIOS. I believe RIOS needs to be changed in order for it to work with any controller including our USB controller. We sourced the controller years after RIOS was written. I don't hold much hope for future RIOS updates.

Thanks for the info re: the extra parts, that's what I was hoping to hear.

Do you own the source to RIOS?
