Dandelion PWM traction system: First rough terrain tests

We are now working in the new PWM traction system and interface for Dandelion, installing all the new circuits and elements into it.

The new chassis improves on the main rover door access (thanks to Carlos and Oscar) and makes things easier to fit into it. However, we still need to clean up cables and components places on it as we can see in the next pictures.

Below, Juan Carlos Gallardo (our Electronics Guru and new team member) is helping with the assembly, as he was able to provide a better power scheme to the PWM driver, the embedded computer and the motor system.


On the picture below, almost all in place...nice cable spaghetti at right!

Next picture shows our new shiny motors in place and the assembly of the wheels:

Here, another picture of the team members working in all areas, like the new concept rover code name "Rhexalion" (more about it soon).


Next, a simple test with wheels on air:

And then, to a more "Moon" Like terrain!!

It was a very exciting couple of working sessions, with a very good end, remotely controlling Dandelion forward, backward, left and right, showing a part of the whole rover potential and of course, the new PWM traction system.

It still needs a proper balance system, but even now we can see the potential of recovering from a tip over and the excellent wheel design for a Moon like terrain.

We are very excited and we hope to be able to show more soon.

Cheers to all!, and keep the good work Team REAL!
