Meet the Bots!
Team Just 'Cuz Robotics has a small army of combat robots which we bring to competitions all over! Watch a few event recaps to learn more about each bot.
Let customers speak for us
from 49 reviewsLove the board in half life makes repairs quick and easy would recommend to any new builds if you have the space
Choosing these was probably overkill for what I'm doing but my last bot's gearbox disintegrated on me so, if nothing else, that won't be a problem this next time. Great quality. If you're wondering if you should buy them, just do it.
Works just as advertised. Small, effective, and very easy to set up. Haven't battle tested it yet but otherwise very happy with the purchase.
Got roofed many times but the escs for my drive kept kicking. Would recommend to anyone looking for beetle weight brushless drive. Worked out of box with no modification to firmware
I bought an SSP to learn how to build a robot, and it certainly delivered. Every part needed, and detailed instructions on how to assemble it (with videos as well). Very satisfied, and would definitely recommend for anyone else who is looking to get started in combat robotics but don't know how to start.
We’ve been using early copies of the WEKA including in one tournament and they’ve been great. We are using them with viper motors and the drive works great. The “Simon says” setup makes wiring these super simple.
The only switch that I had used before was the small fingertech switch which is alright, but soldering to it took some practice and required some splitting to get going. On this switch I was able to directly solder all of my connections through which took far less time. Also if you use a dual motor esc then you have an extra output to potentially hook something up to which I didn't need for my horizontal spinner
The only negative is that you have to solder the washer to the back of the board which I recall being kind of annoying. It's also 4 grams heavier than the fingertech one but that's just negligible on a beetle
These are the smallest and most reliable receivers I've found! In my opinion they're the best choice for any afsdh2a compatible transmitter. There are other similar versions out there that may run different firmware or protocols than your transmitter is set up for so buying straight from JCR is the safest option in my experience.
I've been using these in my antweights for about a year and they're great! I've never experienced meaningful damage to one. I give them to friends regularly to help beef up their designs.
These shoulder bolts were going to cost $120ish from McMaster Carr for a quantity of 10… they work perfectly
as dead shafts for my antweight shuffler, and I cannot recommend these enough.
I've never had any issues with the hex hubs, they just work. I fit them into my own tires because I like more width than the Just Cuz tires. They make your builds easier and stronger.
Amazingly resilient. I use those for most of my builds and I've only had one bend one me and my bot took quite a a hit to do that.
Went to UCR and there were quite a few bots including myself using the Motherboard V2.2. I went through 4 brutal fights and I never once worried that my power would fail.
The lifting forks can take hits and are great at their job. The barbed forks are exceptional (especially at fighting other control bots!), they provide great leverage and are just long enough to outreach many other bots and get under. The barbs help great with keeping the opponent off the floor, and the forks are also durable enough to take direct hits without breaking themselves or damaging the mounts. They’re definitely my preferred front end configuration and it’s worth it to get some spares!
Such a great way to get into combat robotics ! So many great tutorials to watch and component information for beginners. Excellent buy!
