The KSR10 Robotic Arm with the optional USB kit still requires 4 huge batteries to operate.
This is offcourse rather strange, since the arm is now connected to a USB port, which has the ability to supply +5v.
The arm motors only use 3v.
The standard setup uses the 4 batteries in a -3v - 0 - +3v setup, so there is no simple way to just connect the +5v usb power to power the robot’s motors.
Does anyone have a suggestion for a easy setup to prevent me from changing D-cells every time?
(The easiest thing i can think of right now is putting 4 NiMh aa-cells in the compartiment to provide the 2x3v, and integrate a small 220v or solar charger. This still requires one extra cable, and i prefer to use only one cable: USB. But the solar thing is still a nice idea)
