Video: Demo Program on the Pololu 3pi+ 32U4 OLED Robot

via Pololu Blog


This video steps through the demo program on our new 3pi+ 32U4 OLED Robot. The Pololu 3pi+ 32U4 OLED robot is a complete, high-performance mobile platform based on the Arduino-compatible ATmega32U4 MCU. The demo program shown in this video highlights many features of the 3pi+ including bump and line sensors, full 9-axis IMU (three-axis gyro, accelerometer, and compass), micro metal gearmotors and encoders, three user LEDs, and a 128×64 graphical OLED display.

This program ships on all 3pi+ OLED robots, both the assembled and kit versions. It is also included in the example sketches in the Pololu 3pi+ 32U4 Arduino library. More information about the 3pi+ demo program can be found in the user’s guide here.

"Serenade"; 3D Mixed-Media Artwork by Tammy Carmona

via Pololu Blog

Artist Tammy Carmona recently used our laser cutting service to help create her 3D mixed-media artwork, “Serenade”, pictured above. Carmona writes about the piece:

    This mixed-media composition takes classical elements of music, and combines them with art in a decadent, delicious “feast for the eyes”.

    The piano-glossy notes, the authentic violin bows and an actual violin, the laser-cut butterflies, the preserved roses – each element brings a different sensation and a different meaning.

    Themes of rebirth and remembrance permeate this piece. The old violin is reborn with bursts of flowers, the old bows have found a new life supporting musical notes, the flowers are real preserved roses.

The music notes were laser cut out of black cast acrylic, which we stock regularly. The title sign for the piece, pictured below, was cut from the same material and raster engraved. A nice feature of the cast acrylic used in this piece is that it turns frosty white when engraved, which provides high contrast engravings.

For a more detailed description of Carmona’s piece and additional pictures, visit her website here. More information about our laser cutting service can be found here.

Our Black Friday / Cyber Monday sale is back! Visit the sale page to see all the available deals and add the necessary coupons to your cart, including special discounts on the new Zumo 32U4 OLED robots we released earlier today. The sale runs through Monday, November 29, and most of the sale coupons can be used on backorders if we happen to run out of stock, but you should still get your orders as soon as possible since production of many items is limited by the global parts shortages, and lead times to make more can be long.

Please note that during the sale, our order fulfillment times might be longer than usual, but we will do our best to get your order shipped as fast as we can. Additionally, we are closed Thursday, November 25 for Thanksgiving. Happy Thanksgiving!

SpringRC SM-S4303R Continuous Rotation Servo Pair.

We are now offering a two-pack of Surplus SpringRC SM-S4303R Continuous Rotation Servos. These servos are functionally identical to our stock SM-S4303R servos except for the direction of rotation, which is reversed. We are selling them in pairs to help differentiate them. See the product page for more details and specs.

Video: How to Assemble the 3pi+ 32U4 OLED Robot

via Pololu Blog


In case you missed it, the 3pi+ now comes with a graphical OLED display! Accordingly, we have released an updated version of the 3pi+ assembly video. This video walks you through the steps found in the assembly section of the 3pi+ 32U4 User’s Guide. While our user’s guides aim to be as thorough as possible, some things are a lot easier to understand when you actually see someone doing it (like soldering the leads to the motor tabs!), so we hope you find this video a useful addition to our 3pi+ documentation.

Is there something you would like to see in a future 3pi+ video? Let us know in the comments below!
