Just Cuz Robotics 32kg Combat Robot Servo
$25.00
This 32kg Robotics Servo provides true 200 Degree range of motion plus Stall Protection!
Most of the 25kg and 35kg servos on the market use an “optimistic” view of their specs. Those labeled for 270 degrees barely provide 180, and the torque ratings vary from misleading to completely inaccurate.
The Just Cuz 32kg Robotics Servo is different. We stand by our specs. Not only will this servo deliver the angle and torque that it says on the tin, but it’s optimized for use in combat robots.
Before offering these servos, the engineers at Just ‘Cuz Robotics tested a huge range of servos at different price points and found what we probably all knew deep down – almost all of them don’t provide the torque that’s listed on their rating. Looking at eBay and Amazon, whether you pay $20 or $55+, chances are the servo you’re buying won’t provide the torque you think it will, especially with all the nearly identical blue and red 20-35kg variants. Testing shows that some delivered <80% of their labeled torque at voltages higher than they are designed for. After testing many options and reaching out to the manufacturers who made the best ones, ItGresa is excited to offer the Just ‘Cuz 32kg-cm servo!
By implementing stall protection, the current draw of this servo will limit itself to about 0.6 amps after it is stalled continuously for more than 8 seconds. Remove the stall condition and after a few seconds, you can expect to get more power once again over and over, without needing to worry about smoking your servo motor!
Includes all parts pictured including 5 different plastic servo horns, rubber shock isolation mounts, M3 servo spline screw, and four mounting screws.

Included in the box:
- 5 different plastic servo horns
- Rubber shock isolation mounts
- M3 servo spline screw
- Four mounting screws
Design Considerations:
- Our testing shows that you can expect 32kg-cm of torque or more when operating this servo with 8.4V to provide this power. This is the same voltage provided from a 2S lipo without a BEC.
- This servo has a custom controller so standard RC radio equipment will provide a true 200-degree range of motion with the usual 1000-2000us RC signal. No range extender is necessary!
- Pair with our custom Motherboard to avoid smoking your servo with a larger than 2S battery and
- Servo torque is measured in units of torque, which is force * distance. This is very intuitive as it’s simply the lifting force provided by an arm of that length. For example, this servo can lift 32 kg with a 1cm arm or 27.77 lb with a 1-inch arm. (This is over 60 pounds with a very short arm! Avoid getting your fingers pinched…)
- Just ‘Cuz recommends designing so no more than 70% of the peak torque is needed to lift your target mass at the end of your arm. This allows a safety factor in your design. For example, at most a 22-inch arm for 1 pound, 7.4-inch long arm to lift 3 pounds, a 5-inch arm to lift 4.5 pounds, etc.
- Warning: While servos are less dangerous than spinning weapons, it is still strongly recommended that a weapon lock be used with servo-powered weapons as it’s easy to create pinch points with servo-lifting arms and saw arms.

Testing a robot with an active spinning weapon should never be done while maintaining a line of sight with the robot. Ideally, you should be testing inside an enclosed box or arena with at least 1/4″ thick polycarbonate windows or top to see through, and 1/2” or thicker plywood or MDF construction. Operation (Including testing) outside of a suitable arena or test box could cause serious injury.
