Re: CRITICAL_FAULT_INIT_PROPULSION

Everything in that data set looks fine, did you experience the issue while recording the data?? It looks like you powered the machine up, let it sit there for a minute, you power cycled it, and everything came back up normally. I do not see any indication that anything went wrong in the system. If y...

Re: CRITICAL_FAULT_INIT_PROPULSION

I spoke with Chris and he indicated the UI charging electronics for the ABB is being replaced. Assuming that you have charged the ABB with some other method, can you do the following: 1. Start the system 2. Start the demo OCU 3. Record the data until the platform shuts down If the platform is poweri...

Re: CRITICAL_FAULT_INIT_PROPULSION

It looks like the system was completely discharged the first time it went down on 5/29; it shows the aux battery at 4.7% SOC which likely means that the propulsion batteries where low as well. The init propulsion fault you are seeing is caused when an MCU comes up initially but immediately goes down...

Re: Linux based RMP demo OCU

I see from the post that you are using linaro on a ARM core architecture. The OCU was verified in Ubuntu 12.04 (Precise). It was verified to run with python 2.7 (from apt-get). It requires pyserial and pygame (also from apt-get). This version has been tested with 32-bit and 64-bit Ubuntu 12.04 LTS r...

Re: How to solve COMM_FAULT_UI_BAD_MOTION_CMD ?

The fault is due to sending a non-omni motion command (id 0x500 instead of the appropriate 0x600). Omni motion command format differs from the normal 0x500 motion command format to include angle , yawrate and vel (see manual on motion commands), In order to use the OCU with omni you must use a Logit...

Re: Python Segway Initialization

Hello,

I have posted the basic interface example:

Basic threaded RMP interface example

Hope it helps, it should be a good starting point for a user application without all of the OCU GUI complexity.

Basic threaded RMP interface example

This is intended to serve as a basic example on how to interface with the RMP platform via ethernet. The files to modify for your own application would be: EXAMPLE_MAIN.py: the main application that shows how to start the RMP thread, communicate with it and handle the events user_event_handlers.py: ...

Re: Windows 8 driver

You should just be able to go into the device manager and update the driver manually. I have a windows 8 pro at home for testing and can give you instructions if you need them. Let us know how it works out, so we can add some instructions in a sticky.

Re: RMP220 feedback data for odometry - turn in place

Unfortunately there is no differential velocity integrator in the feedback data in the current release. There is plenty of literature that derives dead reckoning from individual wheel velocities which are available. But in order to get reasonable results one would need to run the calculations real-t...
