1346 mecanum
We've been working hard on the chassis and mecanum drive for the last few weeks. This is just a quick little video and some pics of the progress we have made.
This is just a video of some open loop control...We're still working on the closed loop but I think we're pretty close. ![]() ![]() ![]() Our video: http://www.youtube.com/watch?v=xgTJcm9EVnE |

Re: 1346 mecanum
That looks great -- we can't wait to see it in Portland.
It looks like you're using a rubber offset coupling or something similar as suspension. Is that correct? |

Re: 1346 mecanum
I'm not absolutely sure but I think what you are referring to as suspension is actually our optical encoders. We need them for the feedback to control our would be PID controlled drive train.

It seems to be working so far, although the real test will come once we "close the loop" either through the encoders or a gyro. (The programmers always like it when I say stuff like that.) We're at about 55 pounds as seen in video/photos and will be adding a lift/arm combo, pneumatics and ramp to get up to 125 pounds. Um... yeah... I know. We always have to shed a bit of weight just before we ship. I'm guessing it will be only five pounds or so this year. We're looking forward to Portland, too. It is always a good time... and we're bringing some friends from north of the border down with us this time. It will be 2273's first FIRST experience! Jason |
