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 70 reviewsI had been struggling with getting multiple power wires constantly connected in a toggle connector. If I touched the wires just right one component would lose power. I decided to give the all in one PCB board a try to see if that would help. Not only was I able to have secure connections it I got rid of my standalone power switch with harness and my BEC! Things are much more organized and takes up a lot less space. This is differently a great option to simplify your robots wiring and make it more robust
Bought the drive motor/ esc bundle. It was basically plug and play. Worked as it should. Switched one esc to brushed with help from discord. Worked like it should. Highly recommend. (Not combat tested at this moment)
Great motor for my battle bot
I used one of these on my 1lb Aerator, and they never failed me. Way lighter than an external BEC too.
This gear ratio allows for better control. Very happy with them. Thank you Just 'Cuz!
These things are fast. I think that they're a good light-weight alternative to the Fingertech and Repeat Max motors. I bought the 5.2:1 ratios, then realized that a bot should not go 12mph. I'm waiting for a set of 27:1 to come in, those should fix all my issues. Tested them with a higher reduction, their accelleration is insane especially with the 35A escs.
This thing is a beast, both in power and construction. My beetleweight has this, it's a scary powerful weapon, and i'm looking forwards to fighting it. So far, i've only ever had issues with fastening the motor, which can be fixed using blue threadlocker, and the weapon mount hasn't given me issues, as it's not vibrating, rather it's part of the rotating assembly. The whole thing with the snaggletooth blade weighed in at about 13oz. That's a bit nuts, BUT most of that is rotating mass directly tied to the weapon, so free extra hit power.
I like the motor good quality, but thinking it would be a good way to extend the battery in my aeroscout by drawing less amps, however the motor does not have enough power for the plane to leave the ground there for i does not work for my application
I 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.
