The switch should be able to handle a bit over the maximum current that you expect. Our 2 position toggle switch can handle 25A per pole. Often times we run the power wires to both the poles just to be safe.

Hi John,
I have attached a basic schematic for that setup. Please make sure that you are using the correct wire gauge for the project, and Also please verify that the positive and negative pins on the charger are in the right orientation when wiring the XLR charging plug. Verification can be done by plugging in the charger and CAREFULLY using a…[Read more]

Hi JohnGa,
Let me see if I understand this correctly.

–Switch up–
Power form the battery to the sabertooth and any other components

–Switch middle–
Cut power to all components

–Switch down–
No power to any components, but will allow you to charge the batteries.

Let me know if i am not correct.
If you are trying to charge the…[Read more]

Hi Scott,
If you are using the Sabertooth Arduino library, you should be able to just set the motor to spin by using the code below.

Sabertooth ST1(128);
Sabertooth ST2(129); // put these at the top of your code to specify each motor controller.

ST1.motor(1,127); //address 128, motor 1 full power forward
ST2.motor(1,127); //address 129,…[Read more]

If you are using Lead Acid batteries, then yes, that would still work.

Hello,
The reason we use two 12 AWG wires and 2 40 amp breakers is to accommodate the current. 12 AWG wire has a limit of 41 A DC before it starts to fail. The limit for 10 AWG is 55A DC, meaning the wire would start to fail before the breakers trip.

To answer your question, I would suggest not going with the single 10 AWG wire mainly because…[Read more]

Dave,
We prefer to use direct drive whenever possible. It is simpler, requires fewer parts so it’s less expensive, and there’s just not as much that can go wrong. Wheelchair motors can typically support quite a bit of weight so there’s usually no reason to support the shaft with another bearing unless the shaft is fairly long. We use these shafts…[Read more]

Hi Dave,
The easiest way to control the linear actuators would probably be with another motor controller. I don’t have a schematic on hand for controlling linear actuators, but you can treat them the same as you would a motor. Some good motor controllers for the linear actuators (depending on the size of your controllers) is the Syren 10A motor…[Read more]

Hi Dave, you could use either one of the 24V 4A chargers and charge in series or two 12V 10A chargers and charge each battery separately. We typically leave the charger off the robot and just put a connector on the robot but you could also mount it on-board if you’d like…[Read more]

Here is a rough diagram for RC input to two motor controllers. I would hook up the front motors to one of the motor controllers, and the rear motors to the other motor controller.

Hi Dave,
We have a few different options for motor controllers, and it really just depends how you are controlling it, and what you want to do with the motor controller.
The Sabertooth 2×60 motor controller is a good option if you want to control it with RC, or a simple serial connection.

The Roboteq MDC2460 is another really good controller…[Read more]

Unfortunately we do not, we usually don’t have many people that need the index. If you are good with soldering, you might be able to solder a small wire onto the leg of the LS7366R chip.

You are correct, the buffer board does not interface with the index pin directly.

Do you physically have the index pin hooked up to the Arduino? If that is the case, then you should be able read the pulse with a digitalRead and clear the encoder counts that way.

Hello,
Are you trying to reset the number of counts that the arduino is reading? If that is the case, you can use the command “Encoder1.clearEncoderCount()”

The buffer board does not hook directly up to the Index pins of the LS7366R, so sending that value might not help.

Thank you,
Marty

Hi Kurt,
just a few questions.
What are you using for a motor controller?
Are the brakes disengaged?
are you using encoders?
