It's highly likely that I'm going to change the head for something that's definitely non-Bionicle to make this walker more steampunkish. I would still like to stay with the semi-autonomous angle using morse code to control it though. This would give me a certain amount of randomness to the operation of what is a fairly powerful close combat armoured walker. Dice rolls to see if the message was received (1= no go) and then to see if the message is correctly understood (1= moves off in random direction).
Basically in operation the other British scout walker I built earlier would follow on behind this walker and the driver would have it under his control. I've since armed this one man scout walker with a Grimthype Patent Heat Ray Cannon so it now has the ability to defend itself, - though hopefully not against the semi-autonomous walker should it go rogue
