Re: Jetson Nano RoboClaw Control

What is the Serial signal from the Nanos, Voltage amplitude. Eg 3.3v? If it is 1.8v then you will need to add a buffer/level converter between the Nano and the Roboclaw(eg from the Nano TX to Roboclaw S1 pin). Roboclaw can only ready logic down to around 2v. 1.8v signals will not be "seen".

Re: About precharge resistor while using secondary PS for LB

If all switches are off there is no power to the Roboclaw so there shouldnt be any blinking. If you use the bare simplest circuit there is a small amount of power getting to the Roboclaw(1ma with a 1k resistor). This will not usually be enough power to run the Roboclaw but could cause the LEDs to gl...

Re: About precharge resistor while using secondary PS for LB

Yes. Add a secondary pre-charge switch on the resistor. The Resistor is just eh absolute simplest pre-charge option. Adding a manual switch is the second. Then it gets complicated(timing circuit and relay to drive a contactor for the main power connection for example).

Re: Using 3 roboclaw, packet serial, USB

Logic battery primary use is to prevent brownouts(high load causing low main battery voltage) of the main battery from causing a logic reset. In many situations this reset could cause problems. A reset causes an autocalibration of zero in some RC and analog modes so if your control input was not at ...

Re: SpeedAccelDeccelPositionM1

Instead of assuming perfect speed and position control(not possible in the real world), the position system on our controllers breaks the complete movement down into chunks 1/300th of a second in duration. Each interpolated movement is moved to(or attempted to move to). So at the end of all the inte...

Re: Settings resets to default after firmware update

You can revert to 4.1.33 using the windows uninstaller. Once that is done you can read the settings, however you will then need to run the full installer for 4.1.34. A reverted version will not look for an update.

Re: LED Dimmer Remote in RC Mode

On Roboclaw controllers, pulses under 500us and over 2500us are rejected. There may be an old post from before we added the limits but they are there for good reason. We try to reject noise which will tend to be much faster spikes than 500usec.

Re: Manual Homing

That was the first part, setting the inputs to Home(user). This will allow the switch to be triggered when the motor is moving backwards. The second thing to do is make sure when the motor is moving "backwards" it is moving toward the sensor/switch. If it isnt swap the motor wires or set the reverse...

Re: Configuration

You can make a simple 4 wheel rover with a single Roboclaw. Both left motors on one motor channel and both right motors on the other channel. Autonomous doesn't necessarily imply motor encoders(eg you could be autonomous with just a gps module) so you will need to tell me if you or plan to use motor...
