Hello Mal. Thanks for reaching out.

If all you need to do is control motor speeds, you might want to consider a RC control setup. The Sabertooth motor controllers are fairly simple to get up and running with RC control. Please review this manual for Sabertooth hookup and RC implementation.

Hi,
What you can do is solder the cable into the connector and put heat shrink. Attached is a picture with a similar connector doing what I mention.

should add just to point out the obvious, but if you run 1/2 the volts, you speed will be about 1/2 or maybe less depending on the load.

They will run on 12V. However, P=IV. You cut V in half, your power goes in half.

The IG42 78 RPM would be the best bet. if you need it faster you should be fine with he 122RPM. The 240 RPM will probably work with 2WD if you have to go so fast. There is a speed calculator on our how to build a robot support page. We do not have any 12V IG42 motors.

Motor Connector is WM4620-ND
Encoder Connector is 455-1706-ND

Selection of motors is difficult and hard to determine. I requires a lot of engineering and experience. Please look at our support page https://www.superdroidrobots.com/shop/custom.aspx/how-to-build-a-robot/70/ under the motor selection section. the rated torque of the motors is where it run at the best efficiency. They are capable of a lot…[Read more]

The raspberry pi GPIO operates on 3.3 Volt communication. The Sabertooth calls for 5 Volt communication. It would be in your best interest to implement level shifting in order for your logic voltages to be compatible. If you make this change and it still doesn’t work, then making changes in the software will be the next step.

You can make this…[Read more]

If you want to control with RC mode, set 1 off, 2 on, 3 on, 4 off, 5 on, 6 off. Note that to use RC mode, you will need to make sure your PWM signal matches the characteristics of an RC signal: https://en.wikipedia.org/wiki/Servo_control.

Pulse widths must range from about 1 to 2 ms. 1 ms as the smallest width (not 0), 2 ms as the largest width.…[Read more]

Hello Jerry. This is possible. If switch 4 on the Sabertooth is in the ON position, it will enable mixing mode. S1 will act as the drive forward/backwards signal input and S2 will be the turn left/right signal input. With switch 4 OFF, you will have to compute the mixing in order to drive/turn in different directions.

Since you have the…[Read more]

Hi,
We haven’t had to much luck with the auto tune, the best way to do it is manually. If you still have trouble please contact Dimension Engineering.
Thanks.

Hi,

We don’t carry the PING)) sensors and have never used them, so we can’t really provide you any guidance on those.

Regarding the Sabertooth, do you have the motors spinning yet? We always use packetized serial instead of simplified serial. Simplified serial is much more susceptible to noise — if the data transmission gets garbled then there…[Read more]
