They make a lot of sense for stability in slower moving bots. For faster, dynamically balanced ones you really want to get rid of them.

Humans are actually an awesome example of a middle ground between the two. Stubby toes that keep you nice and stable but don’t get in the way when running.

I love the look of toes on robots but I would probably go for some sort of leg+wheel personally :grin:

Edit: to be clear they also participate in grip and transferring effort to the ground when running. But there are ways of doing that with less waisted energy , complexity and mechanical movement. Look for example at Boston Dynamics bipeds, no toes

With the right actuators, it should be possible to mimic human like biomechanics to some extent. And it’s probably better than a solid foot like what Boston Dynamics is doing, but it increases complexity. Although digitigrade is probably the way to go for running purposes.

A wheel in the heel perhaps? With a break to retain the ability to walk?

You pay taxes, so you’re good :+1:

Not if you don’t pay into it (or don’t pay taxes in France)

It’s a wired exclusion to penalize expat 
 The way it’s setup, if you are French and spent enough time outside of France, you have every incentive to stay outside of the country and never move back.
I have friends who moved abroad as kids (their parents moved) then moved to France as adults and had no access to healthcare for several years (until they had payed enough taxes to “qualify”)

I find surprising the reliance on joints for robot design, it seam like compliant mechanism and flexible materials are underutilized.

@enginerd have you played games like Scarp mechanic or GearBlocks?
I get the impression you’d love them

Hey hey hey! Don’t you dare put Heelys on my robot! :joy:
No I meant something along these lines


You can lock the wheels and just walk

You can do whatever you want with your robot, but I’m talking about what I want for myself here.

I’d be ok being your robot, but my body will still be my body. :wink:

Stability might be harder to achieve. Still, large wheels are a good idea.

Ever since I read about Molly Millions with her segmented display, I’ve wanted to implant a clock, however rudimentary. But even as low power as they can be, they’d still need a battery, and then you’d need some way to read it. An external device for power in or display out both render it pointless, but I still want one.

I’d tend to prefer to have wheels for most things, just so long as I can climb stairs.

I’ll take treads over wheels.

Or maybe a bastardization of the two where the wheel can expand and turn into treads

:thinking:

Probably not for me, but it’s cool regardless. And it would be fun to try at least.

Same! That’s would be very efficient, and hopefully comfortable for use in the lab and similar places. Still, fitting in cars could be a problem.

These are called Mattracks, they’re sold as conversions for atv/utv, four wheel drive pickups, and some heavy trucks.

Now imagine them perfectly triangular, with the ability to power the tread (tank / track style), or the ability to rotate the whole triangular assembly. One is fast, the other climbs stairs.

Now put them together and you could climb shit fast.

I call them dumpster pigeons :sweat_smile:
They aggregate near dumps to get in all that rotting trash 
 They will scavenge anything they can before actually hunting 
 Even vulture are more picky about what they eat :roll_eyes:

 ace ventura was made in 1995
 in the very beginning of the film, he loses a raccoon on a zipline rescue mission. he takes it badly and ends up in a Tibetan monk monetary
 a British dude comes to hire him to rescue another animal and at first he refuses, saying he’s a child of light and earthly money has no meaning to him
 then the dude tells him how much they are offering, to which Ace says “reaaheeeheeaaalllyyyyy” because the amount was just so insane he gave up all his enlightenment on the spot.

The amount was $20,000.

PFFFFFFFFFFFFFFF HAHAHAHHAHHAHHAHAH!!!

Still worth more than an empty promise of enlightenment

It’s fairly easy for hobbyists to reduce specific manufacturing processes into absolutes. When you order a 35 ohm resistor you expect the resistor to be 35 ohms
 when you order a batch of PCBs, you expect them to all be identical and produced exactly to your drawings and specifications. This tendency is especially true when software engineers start dabbling with hardware. Software is exactly what it is. It’s only when you realize all the error correction and redundancies going on at the hardware level to run that software faithfully, you start to understand the realities outside of the virtual environment software occupies.

While making flex I found this beauty


Luckily the error was visible to my naked eyes but sometimes these types of manufacturing defects are completely hidden between layers or solder mask.

It is this type of reality that keeps me from jumping into battery powered devices. No matter how perfect your circuit design is, the realities of PCB and component manufacturing mean you could still have a failure that could result in a lethal outcome.

This is why i have to qc the hundreds of repeaters i order. I find on average i have about 10-15% that are out of spec of my level of expectation.

And with my luck if i didnt do this QC, i would have that one that is completely underperforming be the one that goes out to someone with the largest audience of influence.

It is 100% worth the time invested to ensure the product that is produced is up to your standards. We all appreciate it even if we arent aware of the level of detail that you employ.

Working as a quality inspector, I fully get it

Changes the way I look at a lot of stuff

You know, i wouldnt mind a “defective” unit that falls out of spec :slight_smile: you know, for freedom reasons.
