One of the real selling points for potential developers, though, are the array of servos that power the robot's legs, which can operate simultaneously and provide some 40 pounds of lift apiece.
So, a solar power plant equipped with a QBotix robot will generate power at a levelized cost of electricity (LCOE) that is 8 to 15 percent lower than a power plant with single-axis tracker and 15 to 20 percent lower than a power plan with panels in fixed positions.
