It can go much faster. I mapped the throttle inputs to only go up to 50% max, and I still had them set below 50% (so 25% really) for this video. It's way overpowered. :D

Re: Ping pong training robot

Switching the servo motion actually worked really well. Here's a video of the 95% complete device. I'll still post an in-depth one on YouTube later once it's 100% complete. (Video is public, so hopefully there are no issues viewing it.)

Re: Ping pong training robot

I did the first successful tests yesterday. It was a lot of fun. I need to tweak the design in a few places to get it working reliably, though: Lower incline angle for the chute. As it is now, I can't pitch it up more than a few degrees with the tripod, because then the balls roll over the release f...

Re: Ping pong training robot

Would like to see it finished. Perhaps even with a movie in action. I'll definitely make a detailed video when it's all done. In the meantime, here is a test I did a couple weeks ago after I finished the launcher and chute. This was before the base and wiring were done, so I used an R/C transmitter...

Re: Ping pong training robot

Thanks, Chris. I've had a lot of fun working on it so far. By the way, the new (to me anyway) Render workbench is very nice and convenient. Here are a couple pictures of the simplified hopper design. It will attach to the chute with some magnets for ease of removal. The servo in the hopper will rota...

Re: My wearable, arm-strapped keyboard designed in FreeCAD

That's cool. I assume it is 3D printed? Is it hard to get used to typing that way?
