Some notes on the other parts of the build.

I bought a Gimson Robotics linear actuator. Impressed with it so far. Claimed at 29mm/s at 12V, they say it runs comfortably at 18V, which it has done under no load. I will have to run two circuits in the robot an 18V and a 6S ~22.4V circuit. I may have a third 5V circuit for led's etc.

To operate the the linear actuator, I saw in another thread the idea of using two microswitches (10A versions I located) and a servo motor to operate one or the other. I have some small servo's I got for ants, that I will use.

Small recommendation on the microswitches idea: if you're going to do that, I'd recommend commissioning a 3D printed holder for those, as well as to insulate the connectors. I attempted to use the switches with my model, but just found them too fiddly in the end, and so used an ESC instead.

Thanks I will look at what I can do to fix them firmly.y

My biggest concern at this point is weight. When I weighed it last it was 11.5kg, without battery or any other electrics or the front ramp and hinge. This is a problem but not insurmountable.

Chain drive is fitted, linear actuator is fitted. I installed a 12-24v led in rear for "alive/powered" indicator.

I will now continue to work on electronics. Before looking for ways to lose weight from the body.

Possibilities include:
Drilling holes in floor
Drilling holes in frames
Drilling holes in sides
Smaller battery
Lightening the wheels
Smaller battery
