Re: Getting the output force in Newtons You can get the force in Newtons using the field called "force" in PhantomDevice node you are using (assuming you are using H3D and not HAPI directly).

Re: Getting the output force in Newtons I thought of that. I got the output force from the device and I computed the output force like this:
f = sqrt( fx * fx + fy * fy + fz * fz ) f, is the output force, fx, fy and fz is the force applied on each axis. The problem was that the computed applied force surpassed the device's limit: 3.3 N (device's specs). Is my computing method wrong ? Tnx |

Re: Getting the output force in Newtons You can always tell your program to give more force than the device is capable of. It will simply saturate and do its best.

Re: Getting the output force in Newtons If you want to know how much force is actually applied, try using a scale and let the device push on it. Convert from weight to force and substract the device's own weight.
