Waveshare ESP32 robotic arm kit with 5+1 DoF supports ROS2, LeRobot, and Jetson Orin NX integration

RoArm M3 Pro and RoArm M3 S High Torque Serial Bus Servo Robotic Arm Kit

Waveshare has recently released the RoArm-M3-Pro and RoArm-M3-S, a 5+1 DOF high-torque ESP32 robotic arm kit. The main difference between the two is that the RoArm-M3-Pro features all-metal ST3235 bus servos for durability and longevity, on the other hand, the RoArm-M3-S uses standard servo motors which are less durable for long-term use. These robotic arms feature a lightweight structure, a 360° omnidirectional base, and five flexible joints, which together create a 1m workspace with a 200 grams @ 0.5m payload. A 2-DOF wrist joint enables multi-dimensional clamping and precise force control. It integrates an ESP32 MCU, supporting multiple wireless control modes via a web app, it also supports inverse kinematics for accurate positioning, curve velocity control for smooth motion, and adaptive force control. The design is open source and with ROS2 compatibility, it allows secondary development via JSON commands and ESP-NOW for multi-device communication. Compatible with the LeRobot AI framework, […]

MaTouch SmartKnob Assembled ESP32-based rotary knob with touchscreen display sells for $69

Makerfabs has recently released “MaTouch SmartKnob Assembled” based on the SmartKnob View open-source hardware design but enclosed in a plastic case. As a reminder, the SmartKnob View is an ESP32-S3-based DIY rotary knob built around a BLDC motor. With clever software and engineering, the motor is so configured that it can do software configurable detents, haptic feedback, magnetic encoder, and more. It also has a round LCD touchscreen, and USB-C, and features a convenient 3D enclosure that can also be attached to your wall with some sticky pull tabs. The SmartKnob View was a great concept, but its DIY nature made it difficult for many people to get their hands on one as it was never manufactured in quantities. The MaTouch SmartKnob Assembled solves this issue by building upon the original design and comes fully assembled for immediate use. The original module integrates a 240×240 round LCD and uses an […]
