Questions/builds thread.

I have a diagram for a limiter switch circuit at home, I'll post it tonight when I am home.

use diods and microwtiches. when the nut on the threaded rod hits the microswitch it will stop the motor going any further by cutting it off.

The 'Ds' are diodes, and the info at the bottom there is the component you're looking for. Go you your local maplins and they'll sort you out, and also, the diodes have white lines on the which represent the lines on their symbols on this diagram.

Oh, of course! Brilliant! Makes perfect sense, haha. Well, ordered two large micro-switches, a pack of 12 1N5408 diodes and a 15a Electronize ESC.

Ended up not doing any buildy/designy stuff today, hopefully we will get to that tomorrow.

Thanks again.

Took us a bit longer to get going again than expected!

Diodes, microswitches and ESC have arrived, so all that's waiting for us to catch up.

I have some pics of the lifter arms in a mocked up position, latest 3 in the album - http://s1088.photobucket.com/albums/i32 ... elentless/

We just spent an hour planning our lifter's legs and the geometry of the whole thing. We're looking for a ratio of about 4:1, giving us a ROUGH lift time of 1.5 seconds. The travel is about 8-10 inches at the tip. Pretty nippy, certainly fast enough to be useful in battle. :)

Looks good, how is it at self righting?

It looks very nice indeed. Love all the toggle switches on it!
I'll have to come and have a poke around it at the champs :)

Thanks both! I will be returning the favour, Jamie, if you don't mind. :lol:

As for self-righting... well it... d-doesn't. :?

It will drive upside down, though, as the two back wheels still contact the ground when flipped. We were playing with the thought of an arm that comes out when the lifter is extended to flip it over (think razer-style) but we're going to be so close to the weight limit that that's unlikely.

Could always just add a bit to the highest point of the lifter to help it over, if it works either way up its not the end of the world if you don't though :)

Progress! The legs are more or less made, which involved lots of rough measuring and drilling with an angle-grind or two. :wink:

Pics of the setup held in the up position (by clamps, lol) here! - http://s1088.photobucket.com/albums/i32 ... elentless/

Good progress for an evening's bash. :)
