Tru.D 3D

Posted by Jon on 4 May 2016
Tru.D 3D

On Monday, Colin McGinn launched a Kickstarter in order to create a 3D short film using Tru.D 3D, which is a volumetric display system that he designed and patented. The system quickly feeds 3D volumetric objects into a specific viewing area, and each 3D piece forms a frame of an animation to tell a story that can be viewed from any angle.

Included among the Kickstarter rewards is a mini Tru.D 3D machine, which uses our micro metal gearmotors and magnetic encoders to perform a short, two-second animation. The machine is small enough to hold in your hands, and backers have the option of choosing from one of three different animations.

You can find more information on Colin’s project, including the full digital version of the short film, on his Kickstarter.

MSOE underwater robotics ROV

MSOE underwater robotics ROV

The Milwaukee School of Engineering (MSOE) underwater robotics team has been building remotely operated vehicles (ROV) to compete in underwater ROV competitions for several years. In the past, they have created custom motherboards that our 18v15 Simple Motor Controllers could plug directly into:

Custom Simple Motor Controller motherboard for MSOE underwater ROV.

The team is now using our newer G2 High-Power Motor Driver 18v17, which allowed them to save space in the newest iteration of their motherboard.

Maestro automated observatory

Maestro automated observatory

Our customer Robert sent us this spectacular image of NGC 1073 from his backyard observatory after we helped him get a SPDT Relay Carrier working with his Mini-Maestro 18-Channel servo controller. We thought it was pretty cool, so we asked him a bit more about how he captured it and how he is using the Maestro in his observatory. Continued…

Room mapping robot based on the Rover 5 chassis

Posted by Claire on 19 February 2016

This robot, created by theophil on Let’s Make Robots, uses a Rover 5 chassis with encoders, a MinIMU, sonar sensors, and a few expansion plates to do room mapping. Theophil modified the chassis to use Dagu Wild Thumper wheels, and made a custom 3D-printed adapter for connecting the wheels in a compact way. The program for the robot, which is available on GitHub, collects data from the sonar sensors about how far away objects are and creates a grayscale map where the darkness of a pixel corresponds to the robot’s confidence that an obstacle exists in that spot.

Example map made by theophil’s mapping rover.

The program also includes a movement algorithm meant to drive the robot along paths that take it close to many obstacles to increase the accuracy of the sonar sensors. More about theophil’s room mapping robot can be found in his Let’s Make Robots post.

3D-printed mecanum wheel rover

Posted by Grant on 9 February 2016

One of our forum members, gchristopher, posted about his 3D-printed mecanum wheel rover. The rover uses our D24V10F5 5V regulator and some of our TB6612FNG dual motor drivers.

You can find more information on his blog. Additionally, you can find the CAD files on the Thingiverse page, and his original forum post on our forum.

Remember my super cool sumo robot? My sumo robot is different from regular sumo robots. It’s like my sumo robot is in the top percentage of mini sumo robots. Continued…

Video: Phone-controlled BB8 droid build tutorial

Posted by Ryan on 25 January 2016

TechBuilder’s life-size phone-controlled BB8 droid uses a Pololu dual VNH5019 motor driver shield to drive two 19:1 37D metal gearmotors.

For step-by-step instructions for building this droid, see his DIY BB8 Instructables page.

Posted by Ryan on 25 January 2016

This “World’s Fastest” Rubik’s Cube-solving robot uses six DRV8825 stepper motor driver carriers, one for each face.

VertiGo robot drives up walls with propellers

Posted by Ryan on 29 December 2015

VertiGo is a novel robot designed with one main goal: the ability to drive on floors and walls, even if the walls aren’t perfectly flat. To accomplish this, it uses tiltable propellers for propulsion rather than motorized wheels. The propeller tilting is controlled by two Pololu Jrk 21v3 USB motor controllers with feedback. Students at ETH Zurich made this robot in collaboration with Disney Research Zürich.

The Purdue Tuggiteers' spring 2015 senior design project

The Purdue Tuggiteers' spring 2015 senior design project

For their senior design project in the spring semester of this year, a team of Mechanical Engineering students (the Tuggiteers!) from Purdue made a remotely-controlled plane-towing vehicle that uses one of our step-up/step-down regulators. The team shared with us this video of their final review, which demonstrates the vehicle approaching, connecting to, and towing a single-engine aircraft:

This next video captures their vehicle’s first test. An on-board camera allows you to get a 1st-person view of the latch actuating and gripping the aircraft wheel:

We are always excited to see our parts getting used in cool projects, and we were especially excited to see this because it looks way easier than doing it the usual way:
