Polachrome (plastic antweight combat robot)

Description

Polachrome is a 2wd vertical spinner with heavy emphasis on armor and forks. It may be a good starting point for beginners who want to branch out from a kit. I hope this guide outlines everything you need to know to build one of your own.

SAFETY SPIEL:

• Even at 1lb the spinner moves fast enough to cause injury. Always use a weapon lock and keep the robot disabled when not in a safe testing/combat environment. 
• You are responsible for your own safety when building or driving any combat robot

Electronics:

• Drive motors: (2x)
• Spinner motor: It was designed with this in mind but the v3 might be a drop in replacement (you'll want at least 1800 KV)
• Drive ESC: (1x)
• Spinner ESC: (1x)
• Receiver: (1x)
• Power switch (1x)
• Battery: Comes in a 2 pack

Hardware:

• All bolts are m3 and range in length from 6mm to 35mm (I will put in a full breakdown soon)
• This robot uses custom cast urethane wheels: I use this
• You'll probably need some misc wires to connect the spinner ESC to the motor
• All nuts should be m3 nyloc nuts
• Bearing: (1x)

Other required parts:

• I use a flysky fs-ia6 transmitter for the remote you don't need to get one that comes with a transmitter
• You will also need a lipo charger
• I use wago connectors to distribute power from the switch. It would save a ton of space on the inside if you simply soldered them but wagos make repair much easier

Printing tips:

• All robot parts are printed out of overture Super PLA+
• The molds should be printed in tpu
• There should be enough weight headroom for the side forks to be printed solid (99+ walls)
• Weapon should be printed Solid
• Walls should be at least 6
• Brick layers are strongly recommended
• Printing the middle forks on a smooth build plate improves ground game though the same result can probably be gotten through sanding
• The middle forks should be printed with the smallest layer height possible
• The spinner support has a print in place bearing. you will need to put a pause in the print in the slicer, insert the bearing, and continue.
• Supports are recommended

Assembly:

• Mold release is strongly recommended but not required
• Be careful using the right screw lengths when screwing into the spinner motor, if it does not spin freely the bolts are too long
• The electronics are a bit of a squeeze so be patient

Trouble Shooting:

• Depending on how your motors are set up you may need to reverse certain channels on the transmitter for it to drive properly
• Make sure to solder the positive wire to the positive terminal on the motors 
• Due to being somewhat wide the robot turns very quickly. this can be turned down by adjusting the sensitivity on the remote if needed.
• You will need to bind the remote to the receiver. It's best to just look up a guide. There is a bind button on the receiver and remote
• If the spinner is spinning the wrong way just swap two of the wires going to the esc as that changes the direction
