Update
Got some more done to Kaizer today. Finished off the lifter mechanism bar one bolt that I need to buy tomorrow so should hopefully be able to give it a test then. Haven't got it all wired up yet but only got a few more mechanical bits and pieces to do before that.
How it's looking so far, managed to re-use the lid as well, with a bit of trimming:

I had borrowed the batteries out of Carcinus to use for testing, thereby giving 19.2V but this meant that if I wanted to run both robots at the same time I would have to buy another two packs eventually. So in keeping with the current parts recycling philosophy that I'm trying to employ, I've taken a bit of a step backwards technology-wise and opted for some SLAs that have been sitting about to use in the robot. Two 6V, 4.5Ah batteries linked in series for 12V. They have similar dimensions to the Ni-mh packs except for being slightly taller but that works out as an advantage for when it comes to securing the batteries in place.

The drills are 16.8V so they will be undervolted, but they have a top speed of 1000rpm as opposed to the standard 550rpm drill so the robot should still be quite nippy. The lifter drill is 9.6V so it will be slightly overvolted, which should give a nice level of extra speed and power. A full lift of the forks takes a few seconds now (compared to 20 seconds for the old actuator unit) and the distance travelled by the nut on the threaded rod is a mere few inches for full travel so the forks will hopefully be more effective this time round.
Aim to get a bit of a test run in tomorrow so will see how the SLAs cope with it.
