LEGO Spot Micro v2 with a Motorized Chariot

[@MaxBrix]

The length of stride with the feet almost touching is awesome!

[@diywalkers7898]

Great observation, one that only a fellow self-torturing walker builder would see, lol. It also means it needs flat ground, so no walking in streams with rocky bottoms like your 6-bar!

[@carlbModels]

hmmmmmmmmm I'm interested in this mech, it's very clean. Walking machines are certainly a while new game for me, and I love seeing what you lot have done! 👍🍺🇬🇧

[@diywalkers7898]

@@carlbModels It doesn't step high, but this 4-bar linkage does seem to be a candidate for good performance on flat terrain?

[@HiroLaboOECU]

Very smooth passive walking and turning.

[@diywalkers7898]

Ha, only another self-torturing builder of walkers would pick up on the detail that allowing the legs of walk passively means the legs on the outside of a turn can stride faster, somewhat like a car's differential, resulting in smoother turns!

[@oracid]

This gait is really great !

[@diywalkers7898]

Thanks Oracid1! It doesn't step high unfortunately, but it does have consistent footspeed, which makes it a good candidate for walking passively (being pushed/pulled)

@@diywalkers7898 I always use 5 bars, but I am thinking that if I use a servo arm as your 4 bars Crank and an other servo arm as Rocker, it could work. One of your 4 bars don't move. I call this bar g, as "ground". What about if g=0 ? That what I use, in my 5 bars g=0. I explain it here, kzbin.info/www/bejne/epTQeYCOedd8pJI at 1'07".

[@MaxBrix]

How about that stride!

[@diywalkers7898]

Your video explanation of g=0 is great, and powering your rocker with a servo arm is necessary with a 5-bar linkage with 2 DOFs?

[@diywalkers7898]

@@oracid Wait - are you saying that you want to try reducing your 5-bar linkage (4 leg bars + frame) to a 4-bar linkage? While also powering the crank and the rocker? If so this could work but since only 1 DOF the rocker would be constrained to match the crank's movement perfectly, so nothing would be gained but complexity? Or do you mean something else? I love your 5-Bar BTW - if you ever want to write it up on our blog you are of course welcome!

[@bleysingram7789]

Have you tried putting the steering in as a joint between the walker assembly and the motor? like an actual chariot.

[@diywalkers7898]

yes but it causes either the legs or the wheels to get pushed sideways

[@jonskhag]

Hello again, i havent been able to build my walker since i used one of the lever pieces for a build, just an update ;)

[@diywalkers7898]

Thx Jon, I hope your build works out to your satisfaction!

[@jackieglade]

nice! ive made a walker too! are the legs motorized or does the cart just push them?

[@diywalkers7898]

Hi Jackie Glade - if you want, paste a video link to your walker in this comment thread? This build's legs are not motorized - just pushed/pulled by the cart (called "passive walking" by some)
