The Jetson nano is 3.3V logic level so I would try to match that if you can.

It seems like that would work. I’m not sure what logic level it supports.
I reviewed your picture and it seems you have a diode backwards. I couldn’t follow the wires since they go out of frame and are all the same color.

It seems your files failed to upload. Please email them to sdr@sdrobots.com.

The manual has a commands reference starting on page 187.

Yes you can try that. Do you have access to an oscilloscope so you can observe the pulse train? Just measuring the voltage isn’t great for validating the logic level of communication lines.

This is expected. The diodes are for protection. As the documentation states, they are used to clamp the voltage between the resistor and the Jetson Rx.

The key to this circuit is changing the voltage observed by the Jetson Rx. It seems you’ve only checked the Tx voltage of each device.

Are you using a 4.7K Ohm resistor?

It should be set to inverted.

Hi. Sorry, we do not support or sell the BMS1060A. Please contact RoboteQ.

No, removing the diodes would just leave the resistor between the Jetson Rx and the RoboteQ Tx.

We don’t have a sample program available for this but that demo script looks like a good starting point. You can just modify the write payload and read the response to print out.

I’m not familiar with the adapter you’re using. However, we use the circuit on page 179 on a regular basis. You can purchase the PCB here. This circuit would replace your adapter, and as the documentation states, the diodes are optional.

To validate the communication you can open a python terminal on the Jetson and send ASCII queries while…[Read more]

Hello,

When converting RS232 to TTL you have to set the RoboteQ to use inverted serial logic. Please refer to pages 178 and 179 of the RoboteQ user manual.

I would try powering the robot’s Arduino with 5 Volts through the SL header. We have had power issues with the Arduino’s 12v to 5V regulator before. As for the base moving on its own, can you counter this movement with the joysticks? I’m wondering if the joystick potentiometer is off center. If so, there is a slot on the bottom side of the…[Read more]

Hey Zack,

How is the Arduino being powered in the robot? It seems supplying power to the Arduino through the USB cable is correcting the problem.

Likely 2. ignition and starter. without taking apart and troubleshooting the system, we can not answer with any certainty.

Hi. You an use remote control (RC) relays. We use the battle switch https://www.superdroidrobots.com/electrical-parts/Remote-Control/RC-Switches/product=827. You will have to put on the ignition and another on the starter. This is something you have to be very careful with and make sure your fail safes are working properly, etc. so all bad…[Read more]

If the motor is spinning at 120RPM with 24V, changing motor controllers is not going to make it run faster… It sounds like you need to change your gear reduction. The motor is a 10 tooth; what is wheel sprocket size? The bigger that is the more reduction you will have (more torque, less speed). If that is a 40 tooth sprocket, you have a 1:4…[Read more]
