Announcement of Intent to Compete for Gada Prize
For now this is our announcement of our intent to begin a design which will be entered for the Gada Challenge.
In accordance with the Gada Challenge rules, we are documenting this project on this Wiki, and will be posting all information here, as well as in our own blogs on [1]
Summary
Our design will be a pyramidal structure, with a Delta manipulator built from the top down. The print bed will be stationary, and the delta manipulator will carry a mobile print head. Multi-material printing will likely be achieved by either multiple bowden style heads, or by interchangable tools which can be swapped by the manipulator.
We will be building the electronics from scratch, and using a simplified linear actuator model using inexpensive DC Brushless motors for motion control. The entire control system will have constant realtime absolute positional feedback and a closed PID control loop for motion control as well as thermal control.
One feature we will be building into the electronics are hard failsafe states, for motion and thermal, providing hard protection in the event of firmware malfunction.
The project is in it's early infancy right now, more information will be posted here as we develop it.
3rd party credit
- Ottawa Mini Maker Faire, for inspring me to go ahead with this.
- HackLab.to for inspiring me to go ahead with the delta manipulator design, with their prototype delta robot they had at maker faire. (Although my design will be significantly different)
- My wife, Andrea Mumby, for being supportive of this work, including the insane amounts of time and money I've invested into it.
- If I've missed you, I'm sorry, This is a quick post, but I'm sure there are more to come, so to be expanded later.
