This is my new topic/diary thing, as the old one was filled with rubbish.

I haven't really done any work in a while, and as i cant make any of the major events this year im going to slowly work though upgrades, and all the little things I want to do to it that I think would help.

I have given up on Bruiser 2, as to much is wrong with it, after rushing it for the camps. So I have started work on Bruiser (1).

I am planing to fit an electric axe/hammer to bruiser which should sit on the top nicely, and be removable, for when it gets smashed to pieces. At first I will be using a gimpson motor, and 4:1 reduction though chain (stolen from the rotting remains of bruiser 2) but I may change that to 1 or 2 speed 900 size motors with 2 stage reduction, depending on weight and its effectiveness.

The second main upgrade is the drive, I will be improving the mounts to hopefully reduce how often the gear boxes break, The gear ration will be changed from 36:1 to 24:1, to increase the speed, along with the battery being changed from a 12 volt lead acid, to an 18 volt LiPo or NiMh, this will obviously increase the speed further, and increase the amount of current available to the robot, so it should have slightly better acceleration, and pushing power. This theoretically should increase speed by 225%, which should mean the robot can go a new top speed of 11mph (with an allowence for losses) which should make the robot more competitive.

Other upgrades will include wheel protection from and back, and a shampfered back top edge, so it can drive when on the axe mounts, and improved electronics.

Sounds like a plan!

Unfortunately the S900's are no longer in production so you will have to find something else. Not that its hard, just letting you know.

Its a kick for me cos I use 2 to drive my weapon! If they burn out... thats it :-(

yeah i know, i got 4 for bruiser 2, there not actual speed 900s, but there a similar size, with similar specs from eBay, i could never afford the real ones! they seemed a little under powered than the normal speed 900s, but i think that was because of the battery I was using. we'll see

cut the main bulk heads, tested the wire butt welding technique used in liftoff but discovered my battery was flat, so I couldn't continue. I also started fitting the new gears to the motor, but didnt have any grease with me, so thought I better wait so I can do a proper job. Been planning for a while, so I have a good idea of what im going to do.

HDPE for spinner bulkheads? Wouldn't recommend it. Spend the extra money and use nylon

[Bodge Job]

There for axe bulk heads, and will be reinforced, im just using what i have lying around.

[typhoon_driver]

Ahhh right, ignore my comment then. Axe should be ok

[Bodge Job]

yeah, I would never trust HDPE with a spinner, I think an axe should be fine though as it doesn't matter as much if its warped, and is put under less force.

[Liftoff]

tested the wire butt welding technique used in liftoff but discovered my battery was flat, so I couldn't continue.

Good to know it came to good use :wink: Just a bit of advice, don't use crocodile leads like the ones shown in my build diary, I got them melted...for the real weld I used car jump leads - and they still did get slightly warm

[Bodge Job]

yeah I melted some testing a motor, luckily they weren't even mine :P
