After a first competition, terrorising sheffield uni with a spinner, it is clear that a switch is needed. So much re- soldering has been needed after pulling off wires, and before one fight, shorting a lipo. I burnt myself twice in a few minutes, first on a shorted lipo, trying to remove the disc and the lid- 10 screws in total, with a horrible smell coming from the spinner was not a good experience. I then burnt myself on the soldering iron. Again. wood screws will be attempted to stop this as the m6 screws tapped into HDPE doesn't work. Brass and titanium does make nice sparks though. I eventually came second, with a big effort after every fight as a full day of testing the day before has damaged the thread on the HDPE. 3 robots scumbered to Nemesis, and drove off into the pit, despite the disc forcing it to spin in a circle. HDWB won a gladiator despite the steering being reversed that day.

Nemesis mk2 will have aluminium rods for support and no tapped HDPE. Also hopefully it works consistently. I have planned this design in CAD, so no components need to be stacked. Yay.

Nemesis mk2 will also be on 3s. so should have a even more powerful forced turn and will be even more uncontrollable. It will also be a bar.

Congrats on the good performance of your bots. Nemesis was definitely a scary one to fight! It's death hum is terrifying!

The next one will have wheel protection, so it should still be able to drive as it will be harder to hit the tyres off the wheels. both finalists(me and rory) need new blades as both are bent. His is bent more. Nemesis mk 2 shall win next time! Beware those at ant freeze as the next one may work consistently. Love the spinning soundtrack though. 3s should give a more reliable spin as the pink motors are designed for 3-4s, and mk1 was on 2s.

Image with the 3g saved from spokes, we should have enough weight for a switch, which should make the pit easier. At sheffield university, I had to be moved back for every fight.

Nemesis mk1 works much better with the new discs and a switch has been added to help stop shorting things. Mk 2 is completely built but two speed controllers haven't worked as the first one a pad fell off and the next one a connection got removed. we have ordered some more and all 3 bots should make ant freeze
