Tankbot 1.5 - Model to Fab
You’ll see a couple instances of these model-fabrication visuals throughout the blog and site. I like seeing designs come to life - especially if I’m the one fabricating. So, v1.5 does away with a lot of electrical tape, and is a more engineered chassis.
I put a few Antennae on with a double servo gimbal so they move around, this freaked Holly out. I took it off. Had to introduce an external 5V regulator which could output more amperage to the radio to power the servos. The TrexJr motor controller board has a 5V out to power the radio, but it is limited to 50mA, enough to drive the radio receiver, but not servos.
Here is the chassis design, followed by the fabricated piece.
Here is a picture of my use of zip-ties to mount the motors. The rounded plastic pieces constrain the motors vertical freedom, and the zip ties hold the motors in place. Like so:
And here are some more pictures of the model.
