Love the in-depth write-ups, it's a great little machine and enjoying watching it develop. Quite often you have to fight between team members because everyone wants to drive the robot; I love that you guys have a lottery to avoid having to drive 😂

In terms of traction, how much does the robot weigh now? I remember you saying it was quite light at a previous event (4.5kg ish?)
Grippier tyres can help but weight plays a big part too. One of my earlier feathers had 4wd drill drive onto grippy blue wheels but I was disappointed with its lack of pushing ability. Turned out it only weighed 7.5kg so trying to push 12kg machines around was almost impossible. If it's closer to the weight limit, it should be able to hold its own more.

The videos have encouraged me to try and come along to the next one, just realised my current FW build is sportsman legal so will need to get involved.
