    Hello everyone,

    Just a quick introduction, my name is Robert Shalders aka Robo Rob and this build diary will cover the progress of Flatfish from 1.0 to 2 and a bit. I will find the old pictures of the 1st attempt but for now will cover the improvements from Flatfish 2.

    Flatfish 1.0 design goals were to have a low to the ground invertible robot with a geared down motor powering a front scoop/lifter. It partially succeeded, having decent drive and a weapon that couldn't quite lift enough weight to cope with other featherweight robots. So for Flatfish 2 the plan was to convert it into a ram/wedge. Flatfish 1.0 only featured in Robots Live Stevenage 2018.

    Flatfish 2.0 was an improvement on the first one, with caster wheels on the front and a solid wedge. However, this version had drive issues as the wheels were not moving that freely on the chassis which was overloading the motors! Not only that, the steel wedge on the front bent inwards in combat which negated the caster wheels at the front. So back to the drawing board for correcting the design.

    Flatfish 2 and a bit has now got proper washers on the drive shafts to locate the wheels in a better place, as well as fresh orange Banebots wheels with a harder wearing compound. The front wedge is shaped to prevent the steel deforming as it is now fully supported by the HDPE wedgelets.

    The next event planned is Robots Live Stevenage 2019 and after that onto Extreme Robots in 2020.

    More updates and older pictures to follow!

    Nice! The stickers/fish scales decoration is a genius idea. Look forward to seeing more!

    2 775 brushed motors with the Saturn gearboxes from Ranglebox and got spares while they were still on sale. 5S lipo and a junction box to connect it all together. Botbitz 85A ESCs and thick cables. My skills lie in electronics/electrical so the mechanical part of the design was a new challenge for me! The Ranglebox parts have been in the robot since the first iteration.

    Below are a few pictures of the original Flatfish. Credits to Team Panoramic for the Robots Live picture. I use the original scoop as a lucky charm now.
