Vertigo 3lb combat robot (Beetleweight)

thingiverse

First off, a huge shoutout and thanks to redditors u/Xxx_tinyhippo_xxX and u/turdgargler for their incredible help with my combat robot system. I couldn't have completed this project without your invaluable support. (Edit: V1.5 is now out! This version fixes some major errors found within the chassis, and changes the shaft to make putting it, and the weapon on, much easier. The wire holder has also been improved. Lastly, the switch suggestion has been changed from the charger jack version, whose wires burn out with the amount of current going through it, to the mini power switch, which can handle the current better. Look out for version 2.0 by the end of this year, which should have modified, lighter and more powerful electronics, and a stronger frame, and a cheaper, heavier weapon disc!) This is my highly advanced combat robot, Vertigo, weighing in at just 3 pounds. Estimated, you should have about 22 spare grams after building the entire robot. This is designed to be a very competitive design, and not one for a beginner builder! I highly recommend building an antweight robot or a beetleweight wedge before working on this project. You will need: From Botkits: 2 high-torque drive motors at 780RPM and 1 Scorpion DESC motor From Fingertech Robotics: 2 powerful brushless ESC's with 20A capacity 2 Fingertech Inrunners for exceptional speed 2 strong belts rated at 150T 2 precision pulleys rated at 9T 2 robust drum spinner pulleys (No flanges) 1 Mini Power Switch for reliable power control 1 Terminal Block pair for secure connections 1 high-quality wheel hub pair with 4mm diameter and 0.75" length 1 durable wheel pair with 2.25*0.75" dimensions 6-32 1/4" button head screws for secure assembly SCE55 5/16" needle roller bearings for smooth movement From Endbots.com: 22mm gearmotor mounts for precise fitment From Ebay/Amazon: 1 receiver: (No link-choose whatever receiver is compatible for your transmitter.) 18/20 gauge wire for reliable wiring Some pieces of foam for shock insulation 1300MaH battery (I suggest the Tattu 1300mAh 3S 11.1V 45C RC Lipo Battery) for high-performance power 4-40 1/4" countersunk/button head screws for securing the weapon shaft From SendCutSend(Or CNC/Waterjet/Laser cutting company of your choice): Vertigo's robust weapon disc made from 0.5" AR500 steel and Vertigo's durable wedge made from 0.06" grade 5 titanium Assembly should be straightforward, with each part going to its corresponding place. Electronics may be a bit of a tight fit, but careful fitting should allow everything to fit within its assigned spot. Print the bot out of carbon fiber PLA or NylonX...for reference, the chassis without anything on, made out of carbon fiber PLA, weighed about 207 grams. Make sure to print and buy spare parts!
