Re: T_Y's Build Log

Saw blades don't tend to be as successful at this scale, if they do actually cut into the other robot they tend to jam.
Hence the number of one, two or three teeth cutters.

Re: Dorset Robot Championship - 24th November 2018

Will the sumo include minisumo I have just dusted my old ones off and loaded some older code (my latest was rubbish) and two of them seem to be functional. Probably a bit outdated these days but worth a try if your running them.

Re: Peter Wallers Robot Ramblings

The new circuit boards eventually arrived from Ragworm (29 days). These use the larger 5 amp drivers and the new board combines the receiver, motors, power switch and servo and power connectors. https://loxk1q.db.files.1drv.com/y4mYApYtDAKqkX23G2nYqkbJ-Nzo7qSGcpnM-fE7Y8L0S08FlApKx8aFYWwlRtKxA5axHxL7...

Re: PCB Manufacture

Still not managed to get a reply from Ragworm so not very impressed with them. I have found a new full bridge motor drive IC DRV8872 from Texas Instruments. This works from 6.8 to 45 volts so OK for 2 or 3 cells and can supply a peak current of 3.6 amps. So I knocked up a layout and bit the the bull...

Re: PCB Manufacture

I have on several occasions recommended Ragworm for PCB manufacture.
My last order is only a day or so overdue but all attempts to contact them have failed and I see on their facebook page several other people are having the same trouble so I would be careful if you are thinking of placing an order.

Re: Peter Wallers Robot Ramblings

Did some testing at Robonerd yesterday with rather mixed results. I tried the yellow material above against a drum spinner and it failed quite quickly as did a PLA chassis I tried on my Drum spinner. The new Flea spinner seemed to keep losing bind but on the plus side the balance on Combatant was re...

Re: Peter Wallers Robot Ramblings

I went to the TCT exhibition at the NEC yesterday (3D Printing stuff) and got few sample materials to try. The first from Fillammntum is CPE HG100 which is a modified PETG material which is supposed to be strong with good impact resistance. So I have reprinted the major parts of my new cluster flipp...

Re: Is this partlist for a antweight good?

The motors are good but you can get similar ones cheaper on ebay. The controllers I haven't tried but others have recommended them and the spec looks good, obviously you need two. They are the batteries I usually use. The TX Rx I prefer DSM2 / DSMX especially if at a later date you want to use a Ror...

Re: Peter Wallers Robot Ramblings

Having built a new spinner Flea I know there is little opportunity to run it so I have built a new flipper which although not flea sized is around the right weight so the two can be combined as an antweight cluster. https://ol5n6w.db.files.1drv.com/y4mrrjkGtz-ljUgFISdb09KECz4pqdP8rfbG3wAqocb43vC1Y-m...

Re: Peter Wallers Fleas

There are two separate motor gearboxes in one case I found them on ebay a year or so back but they don't seem to be available anymore.
The are much to fast hence the extra gearing which halves the speed but they are still quite quick.

Re: Servo straight to battery

You can leave the negative wire and just move the red wire to the battery plus but after the switch or where it can be turned off.
