Information:
I was really happy with the design of Zenith 4.0, but it had a few problems that I wanted to correct. Firstly, the slippy, unreliable bevel gears were replaced with tracks made of small timing belts. This meant I could have the motors in the back, so I could keep a similar body shape, as well as giving me traction if the front of robot was lifted off the ground. I replaced the big Scorpion Minis with Fingertech TinyESCs, which allowed me to make the whole body a lot smaller. I replaced the incredibly heavy chassis made of 4mm polycarb with a 3d printed one, with a motor "pod" supported by 2mm steel shafts. I designed the pod and chassis in such a way that you have to put an enourmous amount of pressure on the disk in order to have it make contact with the floor. The smaller chassis, smaller components and smaller drive system allowed me to widen the unoccupied space beneath the disk to 100mm. All the extra weight went into the weapon, using a heavier, higher-powered motor and a 42g disk.
Despite it taking me a while to learn how to drive it effectively, mostly due to the enourmous forces of gyroscopic precession, this version has performed excellently. The only problem I've had is that because the teeth are so large, it can sometimes be hard to self right, as the motor has to exert a lot of force to get the disk spinning when it's on its back. The tracks also don't have much grip, as how I designed them didn't allow me to use any grip material. The rubber of the belts is alright, but not great, however I'll have to wait for a brand new version to fix that.
