The MSG gripper uses FOC stepper motors without gearboxes, enabling precise control of gripping force and accurate detection of forces applied by or to the gripper. It is designed for modern embedded AI applications and teleoperation. All hardware designs are open source.

Open-source robot arm meets hand tracking
[📍GitHub below]
It is designed with an industrial mindset but built as a 3D-printed desktop system.
PAROL6 paired with a LEAP Motion controller is a nice example of how accessible robot teleoperation has become.
• Hand motion is streamed to the robot at 100 Hz via UDP
• A pneumatic gripper is controlled by simple fist open and close gestures
• The entire robot stack is open source, from mechanics to control software
Combine that with low-latency hand tracking and you get a very practical platform for learning manipulation, teleoperation, and human-robot interfaces.
This kind of setup is great for experimentation, teleop, data collection, and teaching robots by demonstration
All without proprietary hardware or locked software.

Stacking closed loop stepper drivers to simulate our robotic arm! 🦾
This lets us safely test the comms stack and flash individual motors without risking mechanical damage or tedious disassembly if something goes wrong.
We just shipped motorgui.com v0.0.1 — the first release of our desktop tool for working with our stepper and BLDC motor drivers.
What it can do today:
- Flash application firmware over CAN or UART
- Configure drivers over CAN or UART
- Plot position, speed, and torque/current in real time
- Run calibration and apply presets
Had to disassemble our phantom omni (haptic device from 2009) since one of the pen potentiometers is not working.
Its interested that they use DC motors with gear reducers to drive the first 3 joints. You can see the motor in the second image.
We got some really cool gripper jaws available for our Open Source grippers!
Check it out on our Github:
github.com/Source-Robotics/M…
If you are using our BLDC or STEPFOC drivers check out our web based GUI at: motorgui.com
It supports UART and CAN interface and firmware flashing!
* Also works with our MSG and SSG grippers!
Everything on this table represents the full bill of materials required to bring our PAROL6 robot arm to life! (Except 3D printed parts 😅)
Demo of our latest PAR6 robot running gravity compensation. The robot is from now on in beta access and we will gradually be releasing our progress on github: github.com/PCrnjak/PAR6-Coll…
