Quadruped Robot Can Crawl Under Cars And Jump-Kick-Open Doors

April 1, 2017 by James Hobson 31 Comments

The wheel is a revolutionary invention — as they say — but going back to basics sometimes opens new pathways. Robots that traverse terrain on legs are on the rise, most notably the Boston Dynamics Big Dog series of robots — and [Ghost Robotics]’ Minitaur quadruped aims to keep pace.

One of [Ghost Robotics] founders, [Gavin Knneally] states that co-ordination is one of the main problems to overcome when developing quadruped robots; being designed to clamber across especially harsh terrain, Minitaur’s staccato steps carry it up steep hills, stairs, across ice, and more. Its legs also allow it to adjust its height — the video shows it trot up to a car, hunker down, then begin to waddle underneath with ease.

3D Printing A Stop Motion Animation

September 29, 2016 by James Hobson 21 Comments

How much access do you have to a 3D printer? What would you do if you had weeks of time on your hands and a couple spools of filament lying around? Perhaps you would make a two second stop-motion animation called Bears on Stairs.

An in-house development by London’s DBLG — a creative design studio — shows a smooth animation of a bear — well — climbing stairs, which at first glance appears animated. In reality, 50 printed sculptures each show an instance of the bear’s looping ascent. The entire process took four weeks of printing, sculpture trimming, and the special diligence that comes with making a stop-motion film.

Tree Climber Takes A Page From The Inchworm Book

May 30, 2011 by Mike Szczys 8 Comments

Sharp talons and a strong torso let this robot climb trees, even while carrying a heavy payload. It uses a simple principle, two gripping units allow it to grab onto the tree. These modules alternate, one grips while the torso moves the other up the tree.

You can make out the trio of rods which connect the front and back half of the robot in the image above. Watch the video after the break to see how the motors move these rods with the dexterity of an inchworm, allowing it not only to climb upwards, but to bend and flex to match the contours encountered in the wild.

This was presented at International Conference on Robotics and Automation a few weeks ago. Unfortunately we can only find an abstract for the paper so please leave a link in the comments if you know where to find the full monty.

Climbing Bike Storage Thwarts Thieves?

November 29, 2010 by Mike Szczys 51 Comments

If you’ve got an expensive bike and don’t mind carrying around a whole bunch of extra weight in your courier bag you’ll like this concept. A design team built a pole-climbing bike rack in about 14 days. The video after the break shows the prototyping process as well as the finished “lock” in use. It’s a commercial for the company that employs the designers, but this is one kind of advert we don’t mind watching.

Square channel makes up the body of the device, with a set of Rollerblade wheels which grab a light pole and use three 12V gear motors for climbing. The controller is a wireless fob similar to those used for keyless entry on cars. In the video you can hear the cliché sound of a car alarm being set once the carrier reaches its finished height. Nice.

Vacuum Gloves For Climbing Buildings

Suction is incredibly powerful and can be put to use in several different ways. [Jem Stansfield] built a set of vacuum gloves for a BBC TV series to show how powerful suction really is. He climbed up the side of a 100 foot building, yet had to rely on his safety line near the top. The video of his daring ascension after the jump.

Stairs are one of the most commonly faced mobility challenges for a robot. This robot’s design eliminates the need for a complex drive train or computer, and instead uses a clever mechanical design to climb stairs. Version three of the robot uses five servos modified for continuous rotation, a Picaxe28, sharp IR sensors, and bump sensors.
