The ZA6 robot is built to industrial standards, using EtherCAT servo motors, harmonic gear drives, and aluminum castings. It can carry a 6kg payload with a reach of 975mm, requires only 20A of single-phase 220V ac, and costs less than $20,000. The ZA6 is the only industrial robot to use Python as its programming language. Additionally, the ZA6 is powered by PathPilot, Tormach’s control software based on the Robot Operating System (ROS) software. Because ROS and PathPilot are open-source, the ZA6 is particularly attractive to users who need code transparency or want access to low-level system variables. Other key specifications include a total weight of 65kg (electrical cabinet included), +/- 0.5 mm repeatability, twelve digital inputs and outputs, 24V 2A I/O power supply, and 200-240V ac, 50-60Hz single-phase power.
