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?

Hi Chris,
I would look at the wires running from the lights and make sure that they are still connected to the LED lights. If they are still connected, you can take off the top lid of the robot and see if the connector has come unplugged from the board inside.

If you still can’t get them to work, I would suggest emailing us a picture of the LED…[Read more]

Please see the attached PDF for instructions on getting your RunCam 2 set up as a replacement. Once you have changed those settings you should be good to go.

It looks like you have it! you are probably right about the max speed being 127, and anything over that amount wouldn’t really be doing anything, but just to be on the safe side, I would still constrain it to -127 to 127 just to be safe.

The sign of the motor might change depending how you have your motors hooked up, but it looks like it should…[Read more]

Good, I’m glad it helped. And yes, the math will have to be changed a bit, but it shouldn’t be too hard.

As far as the scaling goes, you are on the right track for the motors. It will take some trial and error, but I think you are off to a good start.

It was hard for me to understand at first as well, so you are not alone!
Ideally you would want to create a system of movement that is independent of forward, back, left, right, and strafe because of the case where you would have to move at a non standard angle (like 37 degrees).

In the RC example, we are taking 3 inputs from the RC controller…[Read more]

I would suggest taking a look at the Sabertooth Arduino Library. Specifically the Packetized Serial example for controlling the motors. This way you will be able to control each wheel individually without having to swap the leads around.

We also have some sample code for a RC Mecanum Robot on our github page that can give you an idea on how to…[Read more]

Hi Scott,
We usually set up the motor controllers so that the front wheels are both on one motor controller, and the rear wheels are on the other. So it looks like you have that set up correctly.

As far as the motor speeds go, it is an intrinsic problem with motors. they will all turn at slightly different speeds. The way that we can correct…[Read more]

if you are ok with laying magnetic tape, it will work well. you can also lay tape to the side of the track to indicate stopping locations, etc. https://www.superdroidrobots.com/shop/item.aspx/roboteq-mgs1600gy-magnetic-guide-sensor/2295/

Sorry, but autonomous is not a simple solution and is expensive, especially in small quantities. There is an IPS system that is IP rated. The IPS system is least expensive of the options available for positioning…

SLAM would be a way to go, but its more money than RTK GPS. Our IP robot is accurate to 2cm.
