ChemBot: a blob-like, shape-shifting robot that inflates and deflates

Mike — Wed, 21 Oct 2009 15:03:07 +0000

Here is a robot that is the first of it’s kind, and a little odd too. This is a blob-like robot that inflates and deflates different areas of the outer body in order to roll a certain direction. The robotic shape-shifting principle is similar to the older robotic wheel design, these robots basically are always “tumbling over” rather than rolling. In order to maintain a constant rolling motion, they basically are in a constant state of “falling over” in a controlled direction. However in contrast to the older wheel design, this robot cannot fall on it’s side because it can roll in any axis. Also, this robot is capable of becoming extremely flat in order to fit under or through something. It’s a brilliant design and is capable of many new kinds of applications. At this point most the development is geared toward the military since there is a demand from DARPA for new kinds of spider-like robots. Some of these new robots could get pretty scary!

Build Your Own Robot Demonstrations, Coming Soon

Mike — Mon, 02 Jun 2008 04:11:31 +0000

DIY, do it yourself robot demonstrations are coming soon to PropellerCode.com. We here at PropellerCode.com com are working on designing low-cost robots with the budget in mind. We like the idea of being able to build nice prototype robots out of low-cost materials and random junk laying around. We may possibly even explore the idea of designing robots out of trash. Ideally the only thing you should have to spend money on when building your robot prototype should be some motors and electronics. Come back soon to see check the progress.

DIY 3D Printer: The CandyFab 4000 Machine

Mike — Wed, 28 May 2008 16:40:15 +0000

Just when you thought the Fabaloo DIY Fab@Home 3D Printer machine was a big sticky mess by squirting goo onto things, there is a new even more sticky 3d Printer design you have to see. The CandyFab 4000 machine by a company called Evil Mad Scientist Laboratories is a DIY 3D printer that utilizes hot air and sugar to craft real life 3D objects. The low-cost method used in this 3d printer is called Selective Hot Air Sintering and Melting (SHASAM). The printer uses sugar as a powder they is laid onto a flat bed in thin layers, then the CNC hot air blower melts the sugar wherever the 3d computer model has a solid body. As each layer finishes a new layer of sugar is put on and the process is repeated until the entire model is complete. After completed, the heated and melted sugar is very hard and glassy. The finished object is a bit rough on the edges, but can be smoothed out. The 3d sugar printer can fabricate fairly large scale objects.

The software for the CandyFab 4000 3D printing machine is designed to be open source for the DIY do it yourself home builder. Evil Mad Scientist Laboratories wants this project to be available for interested hobbyists who want an alternative more affordable rapid prototyping machine. The open source software makes this a project that other people can help improve as well. Hopefully in the near future the designs will be greatly improved with higher resolution prototypes.

The CandyFab 4000 printer is the cheapest 3d printer available today, the total cost of building this 3D printer is only around $1000 plus some spare parts laying around. That is much less than any other design out there. And not only that, you can build it yourself! There are even 3D Google Sketchup models available online for free. All you have to do is order the parts and send some of the parts to local machine shops to make the parts and then you have you very own personal 3d Printer! I think it’s a great project because the materials are so affordable! At the cost of only $1000 you could even build more than one! B)

Robot Monty Throws and Catches a Ball

Mike — Thu, 22 May 2008 12:26:43 +0000

Go Monty! You can do it!
This robot named Monty is a dynamically balancing robot designed and built by Trevor Blackwell of Anybots Inc. This robot has been trained to throw and catch a ball. It appears to drop the ball often, but the robot Monty does catch the ball when Trevor Blackwell throws it. I think this robot is cool because it not only balances on 2 wheels, it also is able to catch a ball with it’s mechanical robot hand and throw it back without falling over.

On the main 3D Solidworks models page you will find Solidworks models in native Solidworks 2008 format. The files are all in .sldprt format for your ease of use!

Build Your Own Mech: Computer Chair

Mike — Tue, 13 May 2008 15:36:52 +0000

Here is a fun little project, build your own mech computer chair and drive it around your office! The M01-Mech robotic computer chair uses a simple bi-ped mechanical walking robot design. It doesn’t move very fast, but it does prove that people can build their own complex robot designs for under $1000. That is cheap for a robot, especially considering the rising cost of building materials. And not only that the M01-Mech can even carry a person around. This walking mechanical chair uses the Parallax Basic Stamp 2 chip to control it. I recommend trying this project out yourself, the Parallax Propeller chip is overall simpler to program than the Parallax Basic Stamp II chip and it costs much less too! Just create an object for driving a a 2 legged robot around and then the code will be simple for the Parallax Propeller chip. I’d like to have my own 2 leg mech to drive around my room too! This 2 leg bi-pod mech is even a chair!
