Re: Is there a stop command?

Luca, I am confused by your two posts. In the first post you expressed a concern that the RMP would continue at the maximum speed after you sent 0 velocity. If you are using acceleration based input mapping then the velocity command word is used to send an acceleration not a velocity. If you send 0 ...

Re: battery autonomy

Luca, If you are interested in the range of any platform based on time you need to start with the total energy on-board and divide by the instantaneous POWER being used. This will leave you with the duration or time that the system can operate at a particular power level. Hello Craig, I would like t...

Re: battery autonomy

This is a very difficult question indeed. We are working on a propulsion model for range but it is not yet complete. For now I would suggest that you drive the platform and monitor the SOC as reported by the system. Using the delta SOC over a known drive profile should allow you to estimate the rang...

Re: Is there a stop command?

Hi, You should be able to set 0 velocity and have the machine decelerate at the deceleration limit until it stops. You need to check / verify several parameters. 1.) Are you using velocity or acceleration based mapping? 2.) What is your decel accelleration limit set at? Please use a CAN sniffing pro...

Re: Measuring battery/motor voltages

Battery and motor voltage are processed internally, to date we haven't thought of a reason why those values would be needed outside the RMP's internal systems. Since every message adds data to the SPI link we have to choose what values we want to transmit over to the user interface processor. Batter...

Re: whats difference in system program between RMP440 and 40

We are aware that the old RMI demo program has problems compiling on newer versions of windows. At this time we cannot provide a different version of the demo code. The compile issues can be fixed but we do not have a new released version at this time. We do not recommend using the old RMI demo code...

Re: Getting started with the 440LE

All batteries MUST be removed before opening the cover on the RMP.

Segway does NOT recommend re-locating any of the circuit boards.

If you need additional space you should consider building another enclosure and bolting it onto the RMP.

Re: Getting started with the 440LE

The ocu cannot find your Flight Force Feedback joystick because it only supports a Logitech Gamepad / Rumblepad which is not the same driver. Force Feedback system use a different driver. The keyboard commands are explained in the file rmp_interface.py starting around line 255. Note that for the key...

Re: whats difference in system program between RMPX440 and 4

As mentioned in the release notes the python code is intended only to be used to guide users in developing their own systems. We would not recommend that you change your code base over the the python, but instead, review the python code and how it sends messages to the platform. You will then be in ...

Re: whats difference in system program between RMPX440 and 4

At a very high level view both systems receive motion commands and send feedback data. Migrating a code base from the 400 architecture to the new RMP440 architecture should not be a particularly difficult task, and the new system allows for much better control of the platform. That being said, much ...
