This page contains a short validation of the Spot robot from Boston Dynamics. These tests were performed commanding the robot via the Clearpath ROS API for Spot. All recorded velocities are from onboard odometry of the robot.
These data are brought to you by CTU-CRAS-Norlab team for DARPA SubT Challenge. Check our Youtube playlist if you want to see more about our team and robots.
Sample ROS driver data including cameras
We have recorded a short bag file of all topics provided by the ROS driver from clearpath. You will need to add github.com/clearpathrobotics/spot_ros to your workspace to be able to play the bag file.
The maximum forward velocity we measured is 1.5 m/s. If the robot is commanded more than 2 m/s, its motion intermittently stops from time to time. BAG file
Sideways motion
The maximum sideways velocity we measured is 0.9 m/s, but a more nominal value would be around 0.6 m/s. BAG file
In-place rotation
The maximum rotational velocity we measured is 1.5 rad/s. BAG file
Endurance
Battery life test was started with original Spot battery charged at 86%. The robot was commanded to rotate in-place with a speed of 1.2 rad/s. The test was aborted after 20 minutes with 63% of battery left. We thus extrapolate that the total battery life is 100 / (86 - 63) * 20 * 60 = 5218 seconds = 87 minutes = 1.45 hours.
The computer that recorded the measurements and commanded the robot was self-powered so it did not drain any power from the robot's battery. BAG file
