A 3D printed robotic digger using BlueBrain. The motor drives can be used to drive the tracks. The 4 servo motor bank can be used to control the boom. Servo motors and links can be used instead on linear actuator.
I've been thinking about doing just this, 3d printing all the parts. Would you be able to share more details of what i'd need on the hardware side to get this running with BlueBrain?
BTW, an impressive 3d printed bulldozer project was just on 3dprint.com: http://3dprint.com/64122/3d-printed-caterpillar-dozer/
Roland - I agree, a fully functional 3D printed digger would be a awesome project. You can plug in up to four Servos directly to the bluebrain, which you can use to control the boom. The dc motor drivers can be used to drive the track.
I'm kinda new to robotics - software side will be no problem but hardware side might take me a while to figure out on my own.
Is this the kind of servo motor I could use for the digger arm control? :
What other components would I need outside of the kit?
Appreciate it if you could spare the time to help me get started
Roland - other than bluebrain and the four servos, you would need two geared dc motors for the tracks. A reasonably high geared motor would be best. I will have a look around.
Those kind of servos (9g servos) are used in (small) robot arms but they aren't design to carry a lot of weight, so how well they would work would depend on the combined printed weight of your digger arms and your expected maximum load carrying capacity; if your building a tiny desktop digger toy that is moving usb memory sticks around then those servos would probably be ok.
I don't have specific numbers for maximum load bearing capacities for those servos (but we're talking low 100's of grams), so what I'm thinking is that you could get those servos to try out with the excellent MeArm robot arm to play and learn from before you build your own robot.
The MeArm can be 3d printed and some one has scaled it up using larger servos.
We've also previoulsy connected a MeArm to a BlueBlain and driven it using an earlier version of our iOS app.
Hope that helps.
Nice forums guys! What software is it? Sorry off topic for first post.
On the servos, as long as those tower pros are fakes they'll be analogue and fine for the job. Genuine ones are digital and although stronger will give your digger the jitters as it tries to adjust to position. For heavier loads go for the metal gear variety, they tend to be stronger.
There wouldn't be much adjustment needed to achieve the curves on the digger with the MeArm and feel to use and adjust the design to your plans.
I wasn't aware the fake ones did that, for the better :), explains a few odd things I've seen before with my mix bag of servos, thanks.

All the best
The MeArm project looks great - I'll build one to get started and hook it up to the BlueBrain when it arrives
Yes, MeArm is a good place to start.
