Hi Trent, we only sell a 10 tooth dshaft sprocket because it is the one we use most often in our robot kits:

I’m not aware of anyone else who is selling them. We can make them custom but it would be quite expensive since we’d have to pay for…[Read more]

Hi Jesse. Are you able to see any printouts from the code you attached? Also, after briefly looking into the Teensy 3.2, it seems the logic voltage is 3.3 Volts. You probably should step this up to 5 Volts using one of our level shifting boards to interface with the Kangaroo.

The mapping really depends how the values are applied in the Arduino code.

Okay. It sounds like you just need to remap the mode switch on the transmitter side to what ever channel pin A14 is connected to on the receiver. If that doesn’t work, printout the input values from the receiver in the Arduino serial monitor while flipping the switch on the transmitter.

If the remote was reset then you might have to remap the mode switch to the correct receiver output. Does the robot still drive when the switch is on “mode 1”? I’m guessing you can still drive because the Arduino assumes mode 0 on startup. I might be a good idea to code a printout of the receiver PWM values in the Arduino source to see what’s going on.

Sorry no. we only have the sizes listed on the site. We can not provide single quantities either, minimum production run is 500.

I have attached some pictures to help illustrate the HC-SR501 functionalities. In order to choose a trigger setting, you must solder the “L” or “H” pad to the center pad.

We had tons of problems with the arduino regulator, since we decided to do it this way we haven’t had problems.

The code use a arduino pin to power the rc receiver, but that is not necessary for the updated schematic. The 12V regulator us often to power relays, and if you use a different type of motor controller.

Hi Daniel

Are you looking at the GitHub code or code for a specific order? It’s most likely to supply power to the receiver if there is no SDR Arduino Mega shield involved. In this case, we power the Arduino with the 5V output from the Sabertooth and use a digital for the receiver. We have found the voltage regulators coming off the Arduino…[Read more]

Hi it looks like there has been some confusion in the questions and answers. What you are trying to do is really difficult and will require a lot of fabrication for steering and a lot of electrical work for the control. In this situation we would probably bypass the scooter electronics all together. You could keep the batteries but would need…[Read more]

I’m not familiar with the motor controller you linked but it seems it would be much easier to connect the output of your Spektrum receiver to a Sabertooth or RoboteQ motor controller. While in RC mode, they calculate the mixing for you and can be adjusted in the firmware settings. If you need something other than a RC output, then I would…[Read more]

When Switch 4 is in the UP position, Mixed mode is selected. In this mode, the R/C signal fed to the S1 input controls the forward/backwards motion of the vehicle. This is usually connected to the throttle channel of a pistol grip transmitter, or the elevator channel of a dual stick transmitter. The R/C signal fed to the S2 input controls the…[Read more]

You will want to read our blog posts on encoders. https://sdrobots.com/encoder-support-overview/ There are also a bunch of links about encoders and speed control at the bottom of the page. You will definitely need to implement speed control and you need to use encoders for that. We would recommend a roboteQ controller. The tires may prove…[Read more]
