Robotics Meetup / Electronics / Software / Robotic Arms / Nov 27 6:30pm Interactive Classroom TODAY

The Robotics SIG are going to be showing off the Robotic Arms at the Robotic Night Out event…

We would like to invite the Electronics Committee and the Software Committee and the Combative Robotic SIG

Anyone interested in Robotics needs to make this meetup. We will be talking about how we can work together and build the robotic and automation community here at the space.

What “robotics sig”?
Presently the robotics effort/interest at DMS is highly fragmented.

EDIT: This is an DPRG event, not a DMS “sig” event. There is a difference.

Should this be posted somewhere visible by the general public?

Yes, I will keep beating this horse until it is clearly dead…

That is why we are meeting.

It is going to be both …

You have talked to the DPRG folks?

We have spoken to them in the past. If it becomes a big deal that we are talking about Robotics at their Robotics meetup, we will change rooms.

Dallas Personal Robotics Group - Robot Builders Night Out. Every Tuesday night you can bring your robot and join us for an informal evening of Robot building, practice for one of our contests, get help with your robotics project, or help others with their projects.

I went out to their meeting tonight …

They are more than happy to have all of us out next week …

I think you should name that thing “Popeye”.

It is now under Interest Groups :slight_smile:

@themitch22 … can you make it Tuesday?

I’d like to figure out how to get a GPU on a line following robot

I know someone is doing cloud vision processing for their line robot.

What do you think can be done with this?

https://www.tensorflow.org/lite/


On mbed (mbed.org)
https://github.com/uTensor/uTensor

My guess is if you do this right, you will not need a pwr sucking gpu on your little mobile bot.

Have you seen some of the challenge maps? No one has completed one yet.

I could be way off, but I think the GPU is much more useful for training as opposed to evaluation of existing weight sets.

If you needed a GPU on a single board computer for TensorFlow etc, I think you’d want to go with NVidia’s Jetson offerings: https://developer.nvidia.com/buy-jetson

Doesn’t the most current RPi have some kind of gpu?

WARNING: I’m not an expert and only dabble and read a bit. Take it all with a huge grain of salt.

I’m not exactly sure what he’s attempting to do, but if he’s wanting to accelerate machine learning training, you would need some sort of “general purpose GPU” (GPGPU) library like Cuda or OpenCL. Pi obviously won’t implement Cuda (NVidia), but there do seem to be some unofficial libraries for OpenCL.

TensorFlow (a really popular ML library) has an unofficial OpenCL support package (which seemingly converts Cuda code to OpenCL on the fly).

I’m not sure how easy it would be to duct tape it up and not sure how well it would perform once it was put together.

I THINK what a lot of people do is train on desktop(s) with big honking “video cards” (most often in Python for ease of use). Once they like their model, they export it to straight C++ code and possibly run it on non-accelerated platforms.

This is today … @ 6:30pm

See you there, @Draco can you bring my floppy disk?

FWIW - some of us are dangerously, dangerously close to solving the challenge course…

For example, my robot, currently named “technical debt”, recently completed the challenge course in 8 minutes with just 3 ‘resets’, where it lost the line and I had to back it up a little by hand to let it try that segment again…

Clay and Ray and Ron are also making good progress, getting close…
