FAQ
Yes — the kit excludes 3D-printed structural parts. You’ll either need access to a 3D printer or a third-party seller to provide those components. The open-source guides specify exact STL files and recommended materials. These guides also define tolerances. This is optional for any AI Robotic Arm Kit that demands customizability.
Absolutely. The AI Robotic Arm Kit is explicitly compatible with Jetson devices. It provides PyTorch-focused examples and deployment tips. These are tailored to edge environments like Jetson Nano, Orin NX, and reComputer Mini configurations.
Performance is hobbyist to research-grade, limited by the servo motors’ resolution and mechanical tolerances. It’s suitable for grasping, pick-and-place, and RL/IL research. However, it is not suitable for high-precision industrial repeatability. Further upgrades and calibration are needed for some AI Robotic Arm Kits.
Leader-follower lets you record demonstrations. It allows a human-guided arm to teach a follower arm in real time. This process is invaluable for imitation learning. It is also crucial for quickly correcting behaviors during reinforcement learning trials.
Yes — assembly guides and calibration tutorials are included. However, beginners should be comfortable with basic wiring. They should also know how to use a 3D printer or source parts. Additionally, installing software dependencies on Jetson or host computers is necessary when setting up an AI Robotic Arm Kit.

Price is nice but the marketing pics show it doing stuff that seems unrealistic for the kit. Kinda annoyed tbh.
Agreed. Treat those videos as aspirational — with enough mods you can get close, but out-of-the-box it’s more of a learning tool.
Fair point — some promotional videos show heavily tuned demos. I tried to be clear about hobby-grade precision versus industrial systems in the verdict.
Long post — hope it’s useful:
I bought the SO-ARM101 Pro to prototype a pick-and-place on the edge with a Jetson Nano.
First week: lots of calibration and a couple of firmware updates.
Second week: integrated a simple CNN for object detection and had it pick up small parts reliably.
Third week: started upgrading brackets to PLA+ to reduce flex — big improvement.
TL;DR: It’s a weekend away from being actually useful, and open-source makes that doable.
I used a lightweight MobileNet SSD, quantized — Nano handled 10-12 FPS, Xavier was much smoother. Depends on your pipeline.
Good to know — thanks for sharing the workflow. 🙏
Fantastic breakdown, Grace. The bracket upgrade tip is especially helpful — I’ll ask the team to link to common 3D-print profiles.
Do you mind sharing the CNN model size? Curious about real-time performance on Nano vs Xavier.
Longer thoughts:
I actually built a small demo with the SO-ARM101 Pro and an NVIDIA Jetson Xavier NX.
Setup took a few evenings — mostly because I printed extra cable clips and re-routed wires.
The open-source drivers worked out of the box but I had to adapt a few ROS nodes to my config.
If you’re comfortable writing a little glue code, this kit becomes really useful.
Noted — I’ll add a power recommendation blurb to the article based on this thread. Thanks!
I used a 12V/10A DC supply and a separate 5V regulator for peripherals. Make sure to test under load — servos spike on startup.
Thanks for sharing these steps! Any tips for power supply sizing for Xavier NX + arm + extra servos?
Appreciate the write-up, Michael. Good point about ROS nodes — we tried to document common Jetson setups but community patches help a lot.
Wow, budget AND open-source? Color me intrigued. But uh — where are all the 3D printed parts mentioned? Mine arrived without anything extra 😂
The Pro without 3D printed parts comes as the electronics/servo bundle; you’re expected to source or print the mechanical brackets if you want alternate configurations. I’ll clarify that in the article.
Same here, Olivia — packaging could be clearer. Took me a minute to realize some mounting pieces are optional community designs.
Not gonna lie, I bought this because the article made it sound too good to pass up 🤷♀️
First weekend: struggled with a dependency hell, and soldering the power leads was fun (not).
Second weekend: finally ran a demo and felt like a champ. 😅
Love that it’s open-source but PLEASE improve the quickstart for newbies — I almost gave up.
If it helps, I can paste my minimal working requirements later in this thread.
That would be life-saving. ty!!
Thanks for the honesty, Ava. We’ll work on a better quickstart with step-by-step screenshots and a verified dependency list.
I’ll compile contributions into a community-start guide and link it at the top of the article once we have them.
Hands-on impressions:
– Assembly: straightforward, clear labeling helps.
– Software: decent examples, some flaky dependencies on older Python versions.
– Motion: pleasantly smooth for demos, but don’t expect industrial repeatability.
– Community: active and helpful, which makes upgrades and mods easier.
Overall: great teaching/prototyping platform for the price.
Could you post the dependency list? I’m terrible with version conflicts 😅
Thanks, Sophia — that aligns with our verdict. I’ll include notes about Python dependency versions that worked for you if you can share them.
Sure — I used Python 3.8, ROS Noetic on Ubuntu 20.04, and pinned the pyserial and numpy versions in my fork. Will upload a gist later.
Great hands-on review — thanks! I’ve been looking for an affordable 6-DOF arm to pair with my Jetson Nano and this looks like a solid option. Curious about the servo quality: does anyone here notice a lot of backlash when doing precise moves?
Thanks, Emma. In my testing the servos are hobby-grade: fine for prototyping and learning, but you’ll notice some backlash compared to industrial gearboxes. Careful tuning and software compensation helps a lot.
Noticed a bit of slop on the gripper on mine, but overall the arm’s performance for the price is impressive. Worth it for tinkering imo.
I had similar thoughts — backlash exists but is manageable with PID tweaks. If you need millimeter-level repeatability, consider upgrading the wrist servos later.
Bought one last month — pretty happy. Easy to hack and the community examples got me moving fast. Recommended for hobbyists!
Glad it worked out for you, Noah. Any mods or add-ons you’d recommend for newcomers?
A simple camera mount and a better gripper were my first upgrades. Also, print a small base to bolt it down — saves a lot of headaches.
Couple of technical notes:
– Kinematics are open and documented; inverse kinematics libraries integrate cleanly.
– Be careful with singularities in some poses; plan motion paths to avoid weird joint flips.
– Wiring harness could be neater, consider heat shrink and strain relief for production use.
Thanks for the detail, Isabella. Useful tip about singularities — I’ll expand the article’s section on motion planning best practices.
Good call on strain relief: our lab had one failure due to a loose connector — easy fix but annoying during demos.
I’m considering this for a university lab — cost is great, but I’m worried about durability in heavy teaching use. Any experiences with long-term reliability? Also, can the arm be taught via demonstration (i.e., kinesthetic teaching) or is it all code?
If you want force/torque based teaching, you’ll need add-on sensors. The arm’s controller can accept external sensor input, though — so integration is possible.
Good questions. For heavy lab use, expect occasional servo replacements over months of high-frequency cycles. The platform supports trajectory control so you can implement kinesthetic-like teaching by recording poses, but it doesn’t have a dedicated torque-sensing mode out of the box.
I’ll add a section on classroom durability and suggested spares to the article — thanks for flagging this.
We used one in a semester-long course: it survived fine with moderate use, but we kept spare servos. For teaching, I wrote a simple jog-and-record interface so students could ‘teach’ sequences without deep ROS knowledge.
One more note: ensure you have a good maintenance protocol (check gear mesh, tighten fasteners) — that extended our units’ lifetime.
If I wanted to use this as a cat entertainment device (teach it to fetch crumpled paper), is it overkill or the perfect tiny robot butler? 😂
Ha — probably overkill but definitely doable. Just make sure the gripper and motion speed are set to be safe around pets.
I trained mine to nudge small objects slowly. The cat ignored it, but the humans were amused. 10/10 would recommend for novelty projects.
If you succeed, please post a video — would love to see a robotic arm get zero respect from a cat.
