We have covered a bunch of cool Servosila robot in the past. This Servosila Robotic Arm is a desktop version that you can control using a joystick. The robotic arm can be mounted on a chassis of a mobile robot. These robots are waterproof and dust proof, so they can withstand rain and snow.
These are attachable payload modules to enhance your existing robots’ capability. They are compatible with Linux or Windows. An ROS package is also available to developers.
