You can use those Servo Drivers but you will have to modify the Arduino code to send commands to those instead of the Sabertooths. From the datasheet it sounds like you will need to put the drivers in Digital Speed Control mode and send it Modbus ASCII commands from the Arduino. I haven’t tried looking but I would expect you can find some Modbus…[Read more]

Hi Aleksandr,

Your motors are intended to be operated using a Servo Motor Driver, which they mention in the link you posted (https://robokits.co.in/motor-drives-drivers/encoder-dc-servo/dc-servo-motor-driver-40v-20a-w-t-step-direction-input). It may be possible to bypass the servo part of it and operate as a basic DC motor but I don’t want to…[Read more]

We would not recommend removing screws. You can remove the spring, but it will not provide a ratchet/lock of the stick and the rubber boot tends to push the stick back close to center, so you will need to remove the boot too.

Sorry, we don’t have this product with shielded wire/ends

Hi. the motors are not sealed. You will need to build an entire housing to keep it watertight.

Hi. The Maestro servo controllers are not intended to be hooked up to a RC receiver. Its meant to replace the RC receiver. If all you want to do is to increase the PWM pulse width you can get a servo stretcher. It goes in between the RC Rx and the servo and will stretch the servo pulse. We do not sell them, but most RC hobby shops will have them.

OK it looks like you’re using hexadecimal for the drive command but uint8 for the stop command. What if you send the stop command in hex? Try using for the stop command.

I understand that you’re not having problems with the drive command. I’m asking you to show me the command just so that I can compare a working command with a command that doesn’t work.

OK let me know the results of that test. And can you also show me the drive command packets you’re using? And when you say the robot doesn’t stop, does it just keep traveling at the last speed you sent it and then stop after 4 seconds or does it just slow down very gradually?

Sure you can email code your code to sdr@sdrobots.com.

And can you show me what you’re calling the “go” and “stop” commands? What are the exact packets that you’re sending?

How are you writing and sending commands to the robot? I would suspect that the delay is due to the Bluetooth. The Arduino is communicating using Serial, meaning you could potentially bypass the Bluetooth and try communicating with it via the USB port as a test. The timer in the code is only used to detect timeouts and stop the motors as a failsafe.
