Desktop Robot

Hi Everyone. Its been a long time since I last posted a robot project on here but I wanted to share my latest project with you all. I have always enjoyed making various types of robot but I have a particular soft spot for desktop robots. I like the idea of a little robot pal sat next to me on the desk that I can develop when I get the spare time.

SKELLY the Skeleton Robot

While it might seem like a long time away to most people, if you’re looking to make an amazing automated display for Halloween, it’s time to start planning! One idea would be an automated skeleton robot like SKELLY.

This particular robot was built using an Arduino Mega, a Cytron PS2 Shield, a modified sensor shield, and a wireless PS2 controller. SKELLY is equipped with a total of eight servos: six for bending his shoulders, elbows and wrists, one for running his mouth, and another for turning his head. There is also a pair of LEDs for eyes, and a small motor in his head with a counterweight that allows him to shake.

SKELLY is programmed using the Visuino visual programming environment. As seen in the videos below, the robot–which is the author’s first–is quite nimble, waving and moving along with an automatic piano!

Design and 3D Print Robots with Interactive Robogami

Robot design traditionally separates the body geometry from the mechanics of the gait, but they both have a profound effect upon one another. What if you could play with both at once, and crank out useful prototypes cheaply using just about any old 3D printer? That’s where Interactive Robogami comes in. It’s a tool from MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) that aims to let people design, simulate, and then build simple robots with a “3D print, then fold” approach. The idea behind the system is partly to take advantage of the rapid prototyping afforded by 3D printers, but mainly it’s to change how the design work is done.

To make a robot, the body geometry and limb design are all done and simulated in the Robogami tool, where different combinations can have a wild effect on locomotion. Once a design is chosen, the end result is a 3D printable flat pack which is then assembled into the final form with a power supply, Arduino, and servo motors.

A white paper is available online and a demonstration video is embedded below. It’s debatable whether these devices on their own qualify as “robots” since they have no sensors, but as a tool to quickly prototype robot body geometries and gaits it’s an excitingly clever idea.

Perhaps there’s an opportunity to enhance the “3D print, then fold” approach Robogami uses with this concept for making flexible prints out of non-flexible material, or incorporating simple 3D printed circuitry.

Thanks to [Adam] for the tip!

8 Lessons from Building the Strandbeest-Style ClearWalker

Here are a few things Jeremy Cook learned (or relearned) while building a ClearWalker Strandbeest and filming it in action.

The post 8 Lessons from Building the Strandbeest-Style ClearWalker appeared first on Make: DIY Projects and Ideas for Makers.

The ClearWalker is an 8-legged, Arduino-powered Strandbeest

What has eight legs, a tail, and is powered by an Arduino Mega? The ClearWalker, of course!

This Strandbeest-style walker employs two motors, controlled by individual H-bridge relay modules to traverse forwards, backwards, and slowly rotate to one side or another via a hesitating leg motion. You can see how the electronics (including a bunch of LEDs) were integrated into this build in the video below.

If you’d like to try a similar control scheme for your ClearWalker/Strandbeest/treaded vehicle using an Arduino and smartphone, you can find it outlined in this Arduino Project Hub post. For the rest of the steps in this quite involved build, and more rather zany inventions, be sure to check out the “Jeremy Cook’s Projects” YouTube page.
