3D Printable Low Cost Servo Based RobotQuad

If you have some extra cheap servos and an Arduino you can use them to make this open source quadruped RobotQuad. It was developed by Regis Hsu and as open source project and its design is updated frequently. It should be a very affordable thing to build as all the servos needed will cost some 20 USD.
In the linked Instructable there are also possibilities to make a remote control unit and IR obstacle detection.

Here is the version 3.0 whit some dance music:

Jebediah the DIY 3D Printable Quadruped Robot

TogleFritz developed a futuristic four legged robot you can make with some basic 3d printing and electronics skills. 

Project description:

Jeb is a quadruped robot that the code in this repository is designed to control. Quadruped robots are robots with four legs. Jeb is designed with three degrees of freedom per leg. Each leg is actuated by three servos. The first servo moves the leg forward/backward, the second servo moves the leg up and down, and the third servo bends the leg in the middle. With four legs and three servos per leg, the robot is driven by 12 servos in total.

Jebediah looks cool (in an insectoid kinda way):

• The microcontroller used is a Botboarduino
• The servo controller is an SSC-32U
• For input the robot uses a wireless Platstation 2
• This repository also includes a library for using NeoPixel LED lighting products from Adafruit.

3D Printed Meliponines Honeycomb

Brothers Fausto and Germano Penello from Brazil developed a 3d printable stingless bee honeycomb which provides a home and reproduction place for wild bees. Since natural habitat of many useful insect species is in danger and there are few opportunities for them in urban environment, this type of ecological micro habitat is more than welcome.
For the hive carrying the combs Fausto used a simple DIY wooden beehive, but he will 3d print one in the future.

Here you can see the 3d printed honeycomb and larval cells, which means that the bees have started their colony.

As many of my family members are beekeepers and I myself am going to beekeeper school, I can testify that bees and other pollinating insects are extremely important for our ecosystem. if they go, they are taking humanity with them! So be king to our six-legged winged friends!

Hydraulic 3D Printed Insectoid Robot

Researchers at MIT CSAIL developed a 3d printing process named "printable hydraulics" where you can 3d print with soft and hard materials at the same time. This creates articulated objects which can move when pressure is applied.
They demonstrated it by 3d printing an insectoid robot that moves when motor and battery is added. Other robotic accessories such as hydraulic grippers can also be 3d printed.

BristleBots 3D Printable Insectoid Robots

Alex Czech from Australia developed this small and simple vibrating movement 3d printed robots. They are powered with a simple battery and low cost DC motor that vibrates their "legs" or bristles. They can be used as an easy educational or toy project.

Here is the BugBot buzzing around:




Here are the small plastic critters from the Bashbot series and they are fighting in the arena, There can be only one.



I wonder how would cats react if I let few of those insectoids go freely on the floor ... we will have to see ...

3d printed food from insects

Many people say that insects are food of the future and will solve world food problems since they are much more efficient in converting plant matter into protein.
Only problem is that most (western) people don't like the look of them. So, here is the solution, powder the insects and 3d print nice appetizing forms from them. Voila! Another world problem solved with 3d printing.
