Structure

Part	Reference	Comment
	Robot frame	The robot frame can be cut in 3mm MDF or PMMA frame.dxf
	Marker	The marker part can be cut in 3mm MDF or PMMA Then, print the relevant robot markers and stick them on it. marker.dxf Robot markers
	Mainboard	Mainboard assembled PCB Click here for more details on electronics
	Structural screws	Those screws are used to fix the motors 6x M3x30 6x M3x8 female-male spacer 6x M3x20 female-male spacer 12x M3 nuts All around the board, we use spacers to protect the robot 10x M3x30 female-male spacer 10x M3x8

Motors and wheels

	GA12-N20 rated 6V 1:210 reduction Hall encoders (7 CPR) 6p JST-ZH connector	3x motors The current reduction trade-off offers a high torque and the speed of the robots are thus limited. This is however not an issue in adversarial game where precision counts more than velocity.
	Motor cables	3x JST-ZH cables (double ended, inversed), 6 pins, length: 5cm. Possible reference: A06ZR06ZR28H51A.
	Motor couplers	Those couplers have internal diameter of 3mm, the small part of the ring is 10mm, the big part is ~22mm and the screw spacing is 16mm.
	3D parts	Option 1, use FDM 3D printer and print the following: 3x Half-wheel part1 (wheel1.stl) 3x Half-wheel part2 (wheel2.stl) 3x Motorbox-top (motorbox_top.stl) 3x Motorbox-bottom (motorbox_bottom.stl) Option 2, print this pack using SLS
	Wheel screws	30x M3x8 screws 30x M3 nuts 60x M3x6 cylindrical shaft See the 3D view
	V623ZZ	60x Bearings for passive wheels
	O-ring 8mm ID, 2mm thick	60x O-ring for passive wheels, those are optional (without them it works as well)

Kicker

	JF-0530B 6V	A small plunger that can be sourced from many online. Used to kick the ball.
	Kicker tip	Can be cut using laser cutter out of MDF or PMMA: kicker_tip_1.dxf : Front for laser, requires engraving for the nut kicker_tip_1.step : Front for CNC kicker_tip_2.dxf : Bottom
	Kicker screws	2x M3x4 screws 2x M3 lockwasher 2x M3 square nuts DIN 562

Powering

	18650 VT6	2x 18650 batteries
	2x18650 holder	Holder for 2x18650 batteries with jack 2.35mm output
