    Adaptive Field Robot changes wheel shape to overcome various terrain

    Arduino Team — January 6th, 2020

    If your robotic vehicle will only work on smooth surfaces, the choice of a wheel is obvious. For more rugged bots, the same applies with knobby wheels. For those that need to operate in both environments, however, the Adaptive Field Robot presents a new solution in the form of wheels that actually change dynamically depending on the terrain.

    This Arduino-powered robot is able to transform its two driving wheels from a nearly circular shape into a claw-like arrangement using secondary motors that rotate along with the wheel assembly.

    When the bot detects an obstacle in its path via an ultrasonic sensor, the motors springs into action, activating a rack-and-pinion system that expands the two halves of the wheel into “claw mode.” 

    Be sure to check out this innovative robot in the video below, including some trial-and-error during the development process.

    Now you can battle real robots over the Internet

    Arduino Team — December 6th, 2019

    Robot-sumo bouts can be a great way to pit your automation skills against others. Participating normally means a lot of hard work to get your bot functioning properly, and likely a fair amount of travel to meet your opponents. SurrogateTV, however, has a new alternative with their SumoBots Battle Royale game that allows you to fight actual robots over the Internet.

    Their customized “pushers” from JSumo are made out of steel sheets, powered by an Arduino, a motor shield and a lithium-ion battery — all housed inside a 3D-printed enclosure — and tracked by a computer vision system. Four motors are used for movement and a servo on the top flips them right side up as needed.

    The ring isn’t just a traditional circle either, but an area that is always dynamically changing. SurrogateTV decided on an interactive floor that drops as the game goes on, voted upon by the chat/viewers. A quick overview of the build process and how it works can be seen in the video below.

    An Arduino-powered fishing pole with automatic casting and reeling

    Arduino Team — December 5th, 2019

    YouTuber MrTeslonian was asked if he could create an automatic fishing pole for someone with a serious disability. While this would seem like a daunting task, he was able to build one using a spring-loaded mechanism, a number of motors, and an Arduino board.

    His portable device takes commands over WiFi, allowing control from a smartphone or computer. When it receives the signal, the pole is automatically pulled back and tension is added to a large spring via a winch. This tension is then released with a servo-actuated system, and a small gearmotor reels the bait back in… hopefully with a fish attached!

    ClearCrawler Strandbeeest walks under Arduino control

    Arduino Team — December 3rd, 2019

    Maker Jeremy S. Cook has been building Theo Jansen-style walkers for literally years, and after several iterations has come up with what he calls the “ClearCrawler.” 

    This little guy stands at just over 15 inches tall — including its comparatively large clear cylindrical head — and travels around via a pair of motors that move four legs on either side like tank treads.

    For control, Cook is using an Arduino Nano onboard, along with a motor driver, plus an Uno and joystick shield as the remote unit. Communication between the two is accomplished by a pair of nRF24L01+ radio modules. 

    Code for the project is available on GitHub, and the build is split up into an electronics and mechanical section in the videos below.

    Meet Aster, the 3D-printed humanoid robot

    Arduino Team — November 29th, 2019

    If you’d like to build your own vaguely humanoid robot, but don’t care about it getting around, then look no farther than Aster. 

    The 3D-printed bot is controlled by an Arduino Uno, with a servo shield to actuate its 16 servo motors. This enables it to move its arms quite dramatically as seen in the video below, along with its head. The legs also appear to be capable of movement, though not meant to walk, and is supported with a column in the middle of its structure.

    Aster’s head display is made out of an old smartphone, and in the demo it shows its eyes as green geometric objects, an animated sketch, and then, somewhat shockingly, as different humans. Print files for the project are available here and the design is actually based on the more expensive Poppy Humanoid.

    Improve human-robot collaboration with GhostAR

    Arduino Team — November 26th, 2019

    As robotics advance, the future could certainly involve humans and automated elements working together as a team. The question then becomes, how do you design such an interaction? A team of researchers from Purdue University attempt to provide a solution with their GhostAR system.

    The setup records human movements for playback later in augmented reality, while a robotic partner is programmed to work around a “ghost” avatar. This enables a user to plan out how to collaborate with the robot and work out kinks before actually performing a task.

    GhostAR’s hardware includes an Oculus Rift headset and IR LED tracking, along with actual robots used in development. Simulation hardware consists of a six-axis Tinkerkit Braccio robot, as well as an Arduino-controlled omni-wheel base that can mount either a robot an arm or a camera as needed.

    More information on the project can be found in the team’s research paper.

    [youtube https://www.youtube.com/watch?v=YQMQQe4y7qE?feature=oembed&w=500&h=281]

    With GhostX, whatever plan a user makes with the ghost form of the robot while wearing an augmented reality head mount is communicated to the real robot through a cloud connection – allowing both the user and robot to know what the other is doing as they perform a task.
    The system also allows the user plan a task directly in time and space and without any programming knowledge.

    First, the user acts out the human part of the task to be completed with a robot. The system then captures the human’s behavior and displays it to the user as an avatar ghost, representing the user’s presence in time and space.

    Using the human ghost as a time-space reference, the user programs the robot via its own ghost to match up with the human’s role. The user and robot then perform the task as their ghosts did.

    While it’s yet to make its premiere, Matt Denton has already built the D-O droid from Star Wars: The Rise of Skywalker using a MKR WiFi 1010 for control, along with a MKR IMU Shield and a MKR Motor Carrier. 

    The droid scoots around on what appears to be one large wheel, which conceals the Arduino boards as well as other electronics, batteries, and mechanical components. Denton’s wheel design is a bit more complicated mechanically than it first appears, as its split into a center section, with thin drive wheels on the side that enable differential steering.

    On top, a cone-shaped head provides sounds and movement, giving the little RC D-O a ton of personality. The droid isn’t quite finished as of the video below, but given how well it works there, the end product should be amazing!

    Rolling robot transformed into a zip lining contraption

    Arduino Team — November 11th, 2019

    MOREbot is an Arduino-powered educational robotic platform that’s currently available for pre-order. While the base kit is geared (literally and figuratively) towards building a small two-motor robot, MORE Technologies CEO Canon Reeves shows off how it can be reconfigured into an RC zip lining device in the video below.

    The project uses the kit’s DC motors for traversing the cable, with O-rings that normally form the tires taken off in order to grip the top of a paracord. Everything is controlled by an Arduino Uno and a motor shield, while a Bluetooth module provides wireless connectivity. Control is via an iPad app, which simply rotates both motors at the same time as needed.

    Since the parts are all modular, Reeves is planning on adding a few other attachments including a GoPro camera mount and perhaps even a servo that lets him drop a payload like a water balloon from it.

    Competition robot picks up (almost) all the balls

    Arduino Team — November 9th, 2019

    For the Warman Design and Build Competition in Sydney last month, Redditor ‘Travman_16 and team created an excellent Arduino-powered entry. The contest involved picking up 20 payloads (AKA balls) from a trough, and delivering them to a target trough several feet away in under 60 seconds.

    Their autonomous project uses Mecanum wheels to move in any direction, plus a four-servo arm to collect balls in a box-like scoop made out of aluminum sheet. 

    An Arduino Mega controls four DC gear motors via four IBT-4 drivers, while a Nano handles the servos. As seen in the video, it pops out of the starting area, sweeps up the balls and places them in the correct area at an impressive ~15 seconds. 

    It manages to secure all but one ball on this run, and although that small omission was frustrating, the robot was still able to take fifth out of 19 teams.

    Since we can’t all have the MIT Mini Cheetah at home, Jegatheesan Soundarapandian decided to make his own version — measuring just 23 cm x 9 cm x 9 cm.

    As shown in the video below, the aptly named “Baby Cheetah” does an amazing job of getting around on four legs, and is not only able to walk upright, but can even move at a crouch, turn, and tilt forwards or backwards.

    The robot is equipped with eight SG90 servos to actuate each 3D-printed leg linage assembly, giving the limbs excellent mobility in a vertical plane. An Arduino Nano is used for control, while an HC-05 Bluetooth module links to a smartphone running a custom app for user interface. 

    More info and Arduino code is available in Soundarapandian’s project write-up.

    UCSD engineers developed electrically-controlled soft robot actuators

    Arduino Team — October 12th, 2019

    Engineers at the University of California San Diego have come up with a way to build soft robots that are compact, portable and multifunctional without the requirement for compressed air. 

    Instead, they’re using a system of tubular actuators made out of heat-sensitive liquid crystal elastomer sheets. Heating elements are placed between two layers of elastomer, which is then rolled up into a cylinder, allowing the tubular digit to bend and contract.

    With this novel method, they’ve been able to build a three-jaw gripper, as well as a robot that walks independently with four legs under Arduino control. While the grippers are slow at this point, taking 30 seconds to bend and minutes to return to their original position, the eventual goal is to have them react at the speed of human muscles.

    As shown in the video below, Tristan Calderbank is a very talented singer and guitar player, but what’s perhaps most interesting about his performance is the percussion section. Instead of a person (or an entire band) standing beside him, a robotic shaker, tambourine, snare drum and bass drum all play together under MIDI control.

    Each device is activated by an HS-311 servo—or two in the case of the snare—powered by an Arduino Uno and MIDI shield. Signals are sent to the Arduino by a laptop running Ableton Live, and servo velocity can be varied to further control sound.

    Arduino Team — September 27th, 2019

    YouTuber Oracid1 has developed a unique family of four-legged robots, dubbed “FiveBarQuads.”

    The quadrupeds all feature ultrasonic sensing for navigation and a body made out of LEGO components — and as seen in the first video below, his latest (and largest) version is able to navigate quite nicely on its own. It’s even able to traverse a grate and maneuver around a potted plant, though chair legs are understandably a bit tricky.

    The robots use an Arduino Uno for control along with a total of 16 micro servos in its shoulders (four each) in order to move the limbs. Two servos are employed to actuate each upper linkage for the legs, which are attached to bottom sections, and finally to the feet portion through a series of joints. This allows for an interesting locomotion capability that could be applicable in a variety of situations.

    Designing a modular and ambidextrous four-fingered robot hand

    Arduino Team — September 4th, 2019

    Gray Eldritch (AKA The Technomanc3r) has been working on a robotic hand for some time now, and has settled (so far) on a design with three independent servo-actuated fingers and a thumb. He’s also implemented a wrist assembly to rotate it back and forth, with an Arduino Uno hidden inside for an entirely self-contained gripper unit.

    Each of the three fingers is controlled by a single MG996R servo, as is the wrist, while the thumb adds a second SG90 servo to allow it to move on two axes. The fingers are modular, so they can be swapped out as needed, and you even change the thumb position for ambidextrous operation. 

    It remains to be seen what Eldritch plans to do with the gripper, but it looks brilliant by itself in the video below.

    If you’ve ever seen a delta 3D printer work, you’ve certainly been amazed at the careful coordination of three motors to accurate position a carriage. While impressive in this role, delta robots can be used for much more, from laser engraving, to pick-and-place operations, to automated phone testing, or even playing the piano.

    To make these systems a bit more accessible, Doan Hong Trung has developed an open source delta robot — dubbed Delta X — based on an Arduino Mega and a RAMPS 1.4 board that can do all of these jobs and more. 

    Details on the modular kit are available here, along with many more clips of it in action. It’s slated to debut on Kickstarter soon, and you can sign up on deltaxrobot.com to be notified when it launches. Design files for the build will be released when successfully funded.

    Arduino Team — July 23rd, 2019

    When you want to build a walking robot, the normal route is to individually control each leg with a number of servos or other actuators. Maker Jeremy S. Cook, however, took a different approach with his ‘ClearCrawler,’ using only a pair of motors to power eight legs. These legs are divided up into sets of four on either side of the bot, allowing for differential control similar to a tank.

    The leg linkage design is based on Theo Jansen’s Strandbeest mechanism, and a clear head is also implemented with a pair of 8×8 MAX7219 LED matrix eyes. Onboard control is handled by an Arduino Nano and an L298N driver board, while an Uno with a joystick shield serves as the user interface. Radio transmission is via two nRF24L01 modules.

    The robot can engage in conversation with its companion, whether it’s answering questions like “What’s your name?” with“My name is Zeus,” or “What’s your favorite movie?” with “I wasn’t that impressed with the special effects, also the plot was not deep.” Zeus even lets Luis know when he “has no idea what to say.”

    Zeus’ communication and movement are accomplished through a variety of hardware, including an Arduino Mega and an AAEON UP board, as well as an Intel RealSense Camera SR300 for vision. Luis is also using CMUSphinx for voice recognition, eSpeak for text-to-speech and AIML chatbot for interactive responses.

    Perhaps we’ll see this ~1/2-sized humanoid traipsing around on its own in the future, though hopefully its comment about “taking over the world” was just a joke!
