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 60 reviewsI love how compact the design is. The simon-says calibration is so intuitive and amazing, I wish all dual ESCs had this feature.
I ran this hub motor on my Antweight vert in Idaho and it absolutely demolished.
I've used these to successfully rehabilitate several destroyed gearboxes with bent or sheared shafts and have been extremely satisfied.
I have nothing bad to say about these, they are a low weight wheel hub with good tolerances and a good geometry for locking in place inside the custom TPU wheels I use on my beetle weight. For best results, use a Dremel to grind a second flat on the motor shaft to give the set screws something to grab onto, and leave a lip at the end so they can't slide off the shaft, then dump a bunch of blue loctite on the set screws so they don't vibrate loose.
I am absolutely floored by the capability of this weapon. I highly recommend to anyone looking for a easy to integrate weapon system. More info below!
I have been wanting to make my own weapon motor for a while. However, with all my other projects, it will be a long while until I am able to tackle that project. I found Seth was developing one and I have used many of his Just 'Cuz Robotics products before which have a reputation of high reliability and longevity within the robot combat environment.
My 3lb bot Defiant has been needing a weapon upgrade for a while. Since I did not want to redesign to implement a better belted system, I found a way to integrate the 1200KV RDY-5536 by changing the uprights of Defiant. There are 4 mounting holes on each side that is easy to attach (be sure not to have the screws go into the rotor). I decided to make small aluminum shims with TPU dampers to mount the motor to the uprights. The overall assembly is easily serviceable and much better protected than an exposed motor. I attempted to use a 55A esc which ended not being enough for my 4s 4 inch weapon disk. I then purchased the Pariah 70A AM32 ESC. That did a trick eliminating overheating and underperformance. Once done, I tested on some of my old frame
I took my new version of Defiant to Champ Makerspace's combat robot event October 5th and ended up winning the championship with a 4-0 record. The weapon fought 4 hard fights with no issues dishing hit after hit. I do recommend replacing the bearings after a certain amount of fights as they start sounding rough. However, the rotor and housing look mint and the coils are still in like new condition.
I highly recommend, a good amount of knowledge of how brushless motors work and function is highly recommended. At least watch Seth's videos prior to taking them apart. Thanks!!!
I’ve tried all sorts of combinations for wiring too/from the power switch over the last 6 years and I LOVE this little guy. Cheap, easy to solder up, and has served me well for the past 3 events with my Beetle. Nice, clean, durable. No notes. 😎
I just recently switched to these gear motors with the Dragon motor combo. I gotta be honest…. I had no idea my Beetle could move that fast and provide that much torque! They worked well in the last event and managed to keep me moving long enough to win a judges decision when my weapon was down! Highly recommend these guys. Just ensure you mount them properly. The single joint between the gearbox and motor isn’t really made to sustain combat hits, so take that into account.
I initially didn’t have the highest review of this board, I had two main issues that were immediately resolved by Seth. You MUST solder the nut to the top side of the board for it to work properly. The initial CAD file for the board was also incorrect, but has been corrected since. In battle this thing was bulletproof!
This kit was the first kit that I got as a beginner builder, and the kit could not have been more simple. The Instruction video and doc was very helpful for understanding how each part gets put together, and covered all outside setup steps that a beginner builder like me would not have known to set up. Overall a very solid kit.
Took about an hour to an hour and a half to build. Instructions were clear and easy (caveat that I've used the motherboard before so I had a head start on soldering etc. for it) and the bot is much faster than I expected! Weka ESC is a nice step up from the old brushless desc. Easy mixing setup and it's tiny. I mostly wanted a simple bot to beat up on with some home designs and the SSP looks to be a small brick of fury.
Held off on reviewing my SSP kit until I had fought it at a competition. On its debut it went 2-2 and narrowly missing out on advancing to the next round due to finishing 9th place.
I have had to adapt the robot to fit UK beetle rules by adding a removable link and adding an LED light. Being about 200g lighter than most UK beetle weights I was worried about being pushed around and smashed to pieces by bigger weapon bars. The kit held up strong and survived many big impacts and no parts were damaged or needed changing after the event. It was fast and had great pushing power as well.
The only criticism I have is the servo is slow and could do with maybe longer forks as I felt robots kept falling off the end of the forks when it lifted and didn’t flip them over.
Looking forward to my next event and further updates to the bot.
Love 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
