Re: Getting started with the 440LE

We don't have a getting started guide released yet. However, we are working on one which should be released in Q1 of 2013. In the mean time please read the documentation in the "RMP Interface Guide (Statically Stable).pdf" which is included in the release package. The files are typically located her...

Re: Charging the RMP X440

Uros, I am the lead electrical engineer for the RMP program. I am also Segway's lead for the battery development. Let me give you some background: In normal operation if the charger is powered up by the AC mains voltage and if there is no battery present there will be two red indicators displayed (O...

Re: Charging the RMP X440

The problem is that the chargers are not consistently getting power. Based on the fact that it worked at one point I would look for an intermittent connection between the AC wall and the platform. You need to verify the connection between the wall and the chargers. Based on the fact that you are not...

Re: Charging the RMP X440

Hi, The auxiliary battery and the propulsion batteries use independent charge circuits so the charge status of one battery will not affect the others. How do you know its not charging? What color lights are you getting on the front panel? Given the states of charge you indicated I would expect you t...

Re: Powering on RMP with USB connected fails

I think the only way to make this work is if you supply +12V from an external supply. It may be possible to rig up a DC/DC converter than can power the +12V Disable line from the +5V on the USB. If the DC/DC got its input from the USB power and had its output ground connected to the board ground the...

Re: Powering on RMP with USB connected fails

The USB hub is transferring power to the RMP causing the centralized controller to boot. Since the Kill switch is not powered up from the +5V of the USB the machine assumes the kill switch has been pressed. I believe a potential work around is to remove the +5V line from the USB cable that connects ...

Re: Hardware Kill and Decel Request

There is a mistake in the documentation Section 3.1 "Hardware Kill" is correct: The opto-coupler is powered up by Pin3 of J8. +5V must be provided to Pin 3 of J8 continuously to prevent the CC from disabling the motor drives. Conveniently, +5V is provided as an output from the CC on Pin 1 of J8. The...

Kinematic and dynamic models

We don’t have kinematic or dynamic models since the operational characteristics of each RMP will vary based end user’s choice of control method and device options.

Wet weather use of RMP

The battery is sealed to the powerbase so that an RMP is water resistant and can be driven through rain, puddles etc. However, if an RMP gets submerged in water (deeper than ~6 inches), then the seal between the user interface box on top and the platform underneath could be compromised and water cou...

Trouble power up the unit

When I push in the on button, I can get it to stay on, but only after a couple of tries. At this point, however, the motor button will not stay in regardless of how many times I try to put it in. The issue is likely due a gap between the switch board and the buttons mounted to the User Interface box...
