After running dark Carrot at a couple of events several mods have been made. The batteries have been bulked up to 24v, to stop the relay drop out we were experiencing at 18v, and because of the increased speed at 24v the wheel size has dropped to 7cm. This removes the ability to do Dantomkia spins, but doesn't warm the motors up so much, as the wheels spin. The original ram jammed open and was replaced by a slightly heavier item, putting the whole build a bit overweight. This could be rectified simply, but to be honest I enter so few competitions that it doesn't seem worth it. The whole set up works remarkably well, and has plenty of shove, the flipper has plenty of flip throwing out all of our opponents at the Inspire event, Cutlet, catrip and Bodgeit, only sucmbing to Rampage 2, due to feeble driving on my part and a broken link in the nicad pack. In theory Dark carrot is Adams robot, but it gets shared around quite a bit. |
For two years in a row I've missed out joining in with Ian Watts robot bash at the Uni. So I'm making sure I've got something running before it swings around again. So I welded a couple of new gearbox cages into the 4 wheel push bot, and dug out a set of Electronize speed controllers. I fitted the titanium plate that has been cluttering the basement for a decade and have been doing some testing with a set of LiON batteries that used to belong to a cordless strimmer, which fell apart from overuse. I've run it up and the battery doesn't really have enough life to power 4 motors, but is useful for testing. I've stuck some old NiMH units on a charge cycle to see if they have enough life for a bout or two. The only things I actually need to "buy" are a 2.4GHz radio set, as the old 40MHz stuff is against the rules these days, so I've ordered a Hobby King 4 channel set for £20 off ebay. Strangely yesterday Mentorn emailed a bunch of robot folk to
