wow.are you gonna build this robot?

#19  

I am working to build a school program that will allow students to decide what kind of robot they want to build, and then build it. They will work with teams to build robots and learn how to design, print, build and program a robot over the first 4 years of the program. The 5th year, they will build a robot of their own.

Prior to this program, students will have gone through up to 2 years of introduction to robots using Six, Roli and JD, and 2 years of implementing the things they learned into existing robot designs.

4th and 5th - Introduction to robotics using ARC and Six, Roli and JD 6th and 7th - Implementation of robotics technology 8th thru 11th - Designing and building robots as a team and building a 3D printer 12th - Build your own robot from the ground up.

Because of this, I am experimenting a lot this summer with a lot of things.

EZ-Builder EZ-SDK Building a Wall-E with the V4 Built a 3D printer Getting back into CAD Printed a Rapiro head to demonstrate what can be done with 3D printers Designing parts for use with various robots.

I am ready for school to start.

I cant wait to start publishing videos. You know, the coolest thing that they will learn is how to teach themselves through research and experimentation. Phase 1 starts September 1st.

wow that just one month from here.i will sure follow your video's.

A little late to the party but, I'm pretty sure the acetone smoothing method only works with ABS parts because they are petroleum based.

Yea, you are right. Acetone is for ABS. I also mix acetone and printed scraps to make a paste that goes inside of open printed parts. This offers a non layered plastic to be joined to the layered plastic, making it much stronger. It also can be used to bond parts together.

It works on abs. I don't like printing pla. It could be the product I was using, but it is very inconsistent compared to abs.
