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.
