It’s time to start a new thread for my current project. This is a 6DOF motion platform using Odrive.
Some background information:
Looking at the internet and some DIY simulator communities, I found that most 6DOF DIY simulators are really complex constructions, some with huge motors and some with many electronic components and some seem to be very expensive.
I wanted to go an Maybe easier and cheaper way……
After a long research on the web I found the Odrive community and the project “Simulator rig with Odrive” by “Zennix”.
I was thrilled about Zennix’s great work and his working 2DOF simulator that I decided to go that way and follow his footsteps with an Odrive system.
But mechanically, I want to go a Little different way. My simulator should be a system with 6DOF. However, these simulators seem to require a lot of engine power because the actuators must carry all the weight of the platform and the driver. Zennix solved this weight problem by using a balanced system with a pivot point near the center of gravity. In this way, the motors have to work only for the movements.
In order to realize a weight-balanced 6DOF system, I would like to pick up some design ideas from a compressed air powered pogo stick (ask the www for details ), which I built a few years ago for my son from scratch. The air spring works so well and was so easy to build, that I want to implement this in my actuators. Hopefully, the benefit will be that I can reduce the idle load of the actuators to zero or even better to support them in vertical accelaration…
So… lot of information for the first post. More details will come up with progress of the project.
Here is a first picture of my current CAD-Model. Thats still in progress but did a good job for the preliminary movement-studys and finding out good overal dimensions.
