    3D-printed continuous rotation servo motor is super smooth

    Reading Time: 2 minutes

    There are three types of motors that makers typically consider: stepper motors, servo motors, and DC motors (either brushed or brushless). Stepper motors are great when you need high precision and torque, but tend to have jerky movement. DC motors work well for high speed movement that doesn’t need any rotational accuracy. Servo motors are somewhat of a compromise between the two. But Aaed Musa’s 3D-printed continuous rotation servo motor is even better, because it is fast, smooth, and accurate.

    This motor works like a standard servo motor, so you can set it to any desired position. But it features continuous rotation, an integrated gearbox to improve torque, very smooth movement, and a magnetic encoder to ensure accurate positioning. As you can see in the video, it responds almost instantly, moves fast, and isn’t jittery at all. Because all of the mechanical parts are 3D-printed, durability may be a concern. But otherwise this is a very attractive option.

    Musa designed this to work with a 600RPM DC gear motor. He then further reduced the output with a 3D-printed gearbox designed in Autodesk Fusion 360. An Arduino Uno board controls the motor through a BTS7960 motor driver and monitors the position with an AS5600 magnetic encoder. The total build cost should be around $30, not including the cost of the Arduino. More details on the project can be found in Muse’s Instructables write-up.

    When classic Vespa scooter design meets Segway technology, you get the Zero Vespa Segway. Created by Spanish design firm Bel & Bel, the Zero functions like any Segway would, on the principle of two electric-powered wheels and a computer-controlled gyroscopic stabilizing system. Each one built to order, with customization options including the paint color, trim, and even custom branding options (logos, etc.). It has a top speed of 12 mph, and can climb 30° inclines – getting about 18 miles on a full charge.

  • Kawasaki J is a Real-Life TRON Light Cycle, Features Shape Shifting 3-Wheel Design

    Kawasaki J is a Real-Life TRON Light Cycle, Features Shape Shifting 3-Wheel Design

    At first glance, this may look like something straight from a science fiction film or anime, but it’s actually just the Kawasaki J Concept, which was unveiled yesterday at the Tokyo Motor Show 2013. Featuring a snazzy 3-wheel design, it’s capable of shape shifting between a low riding position (Sport Mode) and a higher stance (Comfort Mode). Another oddity is that it doesn’t feature neither a wheel or handlebars, it instead has the rider use two levers for steering.

    This is what Gizmag has to say about the Kawasaki J: „Details of the all-electric vehicle’s drive-train are scant, but Kawasaki says the J concept makes use of its proprietary battery management technology and GIGACELL high-capacity nickel-metal hydride battery.“
