FIRST Saturday Evening

A prototype for our end effector.

This is a prototype end effector. The silver part is the important part; the black pole sets it at feeder-station-height when on the floor. In the final version, the effector will likely be aluminum tube, and it will be able to go down to a vertical position, probaby powered by a denso motor.

Our prototype with red triangle

Here we show it in use. It’s amazing how securely this holds all three shapes. All we have to do is position the end effector over a scoring peg, slide it down and the game piece slides right on. Ought to be ultra effective when coupled with our mecanum drive.

We’ll meet with a fellow from Neff Engineering, the local 8020 distributor, in the next two weeks to design our lift. We’re still working out the details whether to go with plastic slide inserts or rollers. In all, the whole lift will weigh no more than 18 lbs.

We’re conjuring up ideas about a potential floor loader; what we have may look vaguely like what 1024 used in 2008 (as I recall, that was a fairly good year for the Kil-A-Bytes).

We’ve got the wood and pool noodles cut for bumpers; if we can track down a seamstress (or seamster?) we’ll do bumpers a la 2040 DERT.

We also finished the scoring rack, a feeder station, and lane. We organized the FTC materials and started throwing around minibot ideas, but nothing in earnest.

It is fantastic having 6 engineers and several parents as regulars to our build sessions. So much more productive.

    I think your triangle is very overinflated.

      We’re surprised that it hasn’t lost air, especially considering how cold the workshop is. The game pieces are very high quality.

        My team’s triangles are normal size at the corners and thinner on the edges – it looks like yours are normal size at the edges and near bursting at the corners. Maybe mine are underinflated.
