Riverlands Brews & Bots Recap

What has changed for this event?

Swapped back to brushless for this event, specifically the Repeat MK3’s. At the last event in Iowa I utilized brushed motors and they didn’t seem to be up for the task.
A new 4in1 was utilized with 2mm bullet connectors for all of the motor phases.
Utilized the balance connector on the battery to feed 2 cells worth of power to the receiver.
Revised wheel hub design that puts less tension on the belt.
Replaced the 1” wheels with 1.5” and added a traction coat.
Downsized the battery to a 380 mAh 3 cell
Tested out the ER4 receiver in full combat

Left gearbox took a direct hit on the pulley and slightly bent the shaft.
Wheels took most of the hits and held up pretty well, little bit wobbly at the end.

Wheels took pretty much every hit, few good cuts but still had reasonable drive with them.
Left side was still driving a bit poor from prior fight, took another small hit on the pulley.

Phase wires came loose on right motor after a good impact, this hobbled one drive pod early.
The weird bounce hit at the end of the fight managed to feed the left pulley into his weapon in mid air.

Drive pulleys need to have a guard added
Phase wires need to be secured better, some sort of guard or strain relief should do the trick
Need to have more finite control over the weapon speed, it was to difficult to change weapon speed during the match.
Need to have all spares built up, this was a known issue going into this event but will be addressed for 2023 MRCA finals
Going to test retaining the battery with a Velcro strip
The robot is over 50grams light, need to find some spots to put all that weight
