Kevin's mini-sumo robot: Roku
- 22 March 2023Hello, George.
Please note that our company name is Pololu (not "Polulu").
When using the speed commands in our Zumo Arduino libraries, a value of 400 corresponds to 100% duty cycle (i.e. driving the motor at the full battery voltage). So, you cannot increase the speed beyond that programatically. You might consider replacing your Micro Metal Gearmotors with different ones with a lower gear ratio.

Introducing the 3pi+ 2040 Robot
- 15 March 2023Hello, Edward.
It is probably possible to solder headers to the expansion areas after the robot has been assembled, but some of them are very close to the plastic chassis (such as the ones accessible from inside the battery compartment). So, I would recommend removing the board to avoid melting the chassis.
The chassis was designed to allow for removing the electronics after assembly. After removing the skirt and screws, you can carefully lift the PCB, motors, and battery contacts off of the chassis as one assembled unit. The motors will only be connected to the chassis by the soldered jumper wires, so I recommend being extra careful with them.

Introducing the 3pi+ 2040 Robot
- 13 March 2023Hello, Charles.
That sounds awesome! We have added 3D STEP models of the chassis it to the Resources tab of the 3pi 2040 Robot product pages. The skirt is a separate body in the 3pi-plus-chassis-kit-skirt.step file, so you should be able to isolate it, but if you run into problems please email us and we can help further.

New Pololu distance sensors with digital and pulse width outputs
- 31 January 2023Hello, Arash.
These boards use an 850nm emitter, so you would need to use a material that is transparent to that wavelength. I recommend looking at documentation for sensor components (e.g. like these) for more information and ideas.
For example, they link to these, which might work for you (although please note that we have not specifically tried them).

New product: TB67H420FTG Dual/Single Motor Driver Carrier
- 26 January 2023Hello, Brenda.
We cannot give any meaningful suggestions without more details about your setup and the problem you are having, but this is not an appropriate place to get into troubleshooting. If you post your request for help on our forum or email us and include more details about what you are doing (including pictures of your setup that show all of your connections), we would be glad to help. Additionally, you can find some general troubleshooting advice and recommendations for what information you should include when you contact us on our support page.

Raspberry Pi Solar Tracker
- 7 December 2022Hello, Robert.
Unfortunately, we do not have any affiliation with the creator of this project or Helistat Control, so we do not have any advice or suggestions.

Video: Getting started with the Maestro
- 2 December 2022Hello. Jim.
In the video from this blog post, we just used some #2-56 screws to mount the Maestro directly to the Pololu RP5/Rover 5 Expansion Plate, but our #2-56 M-F standoffs (or #2-56 F-F standoffs if you prefer) should work to elevate it if that's what you are after. I am not sure what you mean when you say the threaded portion is too big, but if you continue having problems with it, you can post on our forum or email us with more details, such as pictures, and I would be happy to help there.

Addressable through-hole RGB LEDs are back
- 30 November 2022Hello, James.
Yes, you can control each LED individually (each one has its own WS2811 driver, and the 3 channels control the red, green, and blue output).
Separately, please note that LED color data is encoded in a green-red-blue order (GRB), so compared to the WS2812, the red and green colors are swapped.

Video: Getting started with the Maestro
- 7 November 2022Hello, Colin.
Thank you for your suggestion. We will keep it in mind. In the meantime, you can find information about using the Maestro with an Arduino (such as connections and Maestro configuration settings) in the README of our Maestro Servo Controller library for Arduino. Additionally, that library has various examples. If you have additional questions, you can post a request for help on our forum, and we would be glad to help.

New product: Tic 36v4 USB Multi-Interface High-Power Stepper Motor Controller
- 3 November 2022Hello, Kevin.
To use a 6-lead stepper motor like product #1475 as a bipolar stepper motor, you can leave the center tap wires (yellow and white) disconnected as they are not used for bipolar operation.
