| For the motors, the //Explorer// board uses 2 pin Molex connectors the same as found in many PC power supplies (internal plug connecting the mains wires, c0mes with high current wires attached). I modified an 8 AA cell battery pack to accommodate just 6 AA cells to provide a 7.2 to 8.4V battery for the system, found a plug (ex PC speaker I think) that matched the //Explorer// power jack. Strangely the //Explorer// board has large-pinned sockets for the outgoing power to the motors, but only a tiny battery socket through which all that power has to come! | For the motors, the //Explorer// board uses 2 pin Molex connectors the same as found in many PC power supplies (internal plug connecting the mains wires, c0mes with high current wires attached).

| | ===== Conclusions ===== |
| | Experimentation with this robot platform was cut short by one of the motors stripping a gear, perhaps the motors were more worn out than I remember, or the plastic/nylon gears had simply dried out and become brittle with age. Unfortunately I haven't got an alternative low geared motors to replace it with. |
