Snake Robot #2 PREVIEW VERSION

It's time to finish the snake robot and see if I can ride it. It has eight wheels and four segments with large servos between them that cause it to flex in both directions. It's modular - each segment is linked together with a serial bus and houses its own power and Arduino.

Now it makes sense as to why you didn't need handlebars. 😄 Great project.

Michael Bigby

Awesome vid as usual! It feels like the arch axis wiper motors could be replaced with some passive suspension. Small shock and coil? How much does your weight need to be spread to all four segments?

I wonder if maybe you need to mount the seat much higher up on a standoff platform, then you could have space for foot rests and allowance for the machine to bend up and down (with beefier motors and gearing of course) without affecting the rider position. The handle bars would still be problematic unless you could have some kind of mechanism to adjust the height (and possibly the lateral position) dynamically to offset the bending motion.

So cool. I wonder if you made a snake with wheels that only spun in one direction (maybe with a ratchet?) if you could make it so it uses serpentine locomotion! What a neat idea this is though, the result is awesome.

It does look like the hinge mechanism protrudes underneath quite a bit when bending up. #wheelclearance Beyond that the whole project is wild. Drives great and looks neatly distinct from other builds I've seen. Well done!

I think the actuators all need to be strong enough to lift my weight. Probably a 10:1 reduction on each one would be enough torque.

It does definitely get grounded when it bends, but that's something to consider for the next one.

You obviously get a lot of use out of the LulzBot printers, can you share your unfiltered opinion on how well they hold up and retain tolerances?

I've only ever used Lulzbot printers, so it's hard to make a comparison, but they work well for me. I tend to design around what I know will come out of internal holes etc, so I don't know how tolerances compare to other machines. Reliability is very good - otherwise I wouldn't get the projects done in time.
