Robotic Following Cart to Replace Light Duty Tractor Tasks?

[candersen10]

Very impressive, am assuming you did this through a memory function; i.e. follow me once and them memorize this route?

Liked fact dog did not confuse it though I wonder how it would halt/brake that line of carts in a must stop now situation.
What kind of tires are you running on it now?

Could one go pick up and retrieve parking lot shopping carts ?

Stopping power is quite good we've seen. Each robot can put about 4-5 HP, and thus tow about 5000 pounds on hard surfaces (each of those green carts weights about 500-550 lbs).

As of now, you train the robot once to memorize a route, and then it can travel along that learned route both directions over multiple days/weeks/months while towing vehicles. Were a dog to confuse it, we would have a real problem...The one site where we were testing has 15,000 of those carts to give some idea of scale.

Here's a Gen 5 Burro.

Hello Candersen10, re post 221 and sounds.
1) AVOID the LOUD surround type noise that Cat used on it's machines. It disturbs/irritates everybody and FAILS to tell the people at risk of being runover they need to pay attention.
2) Use highly directional sound for movement so when people hear it they know they NEED to pay attention.
3)Offer a choice of sounds as some people have specific frequency deafness,(some sounds will slice through high background sound), other people are just hyper sensitive to certain sounds. I am one. (people find my phone and text ringtone weird as they have been selected to cut through engine noise, - I drive tractors.)
It has been facinating watching this machine evolve.
Have you thought about a possible market in the horse set? carting hay grain etc.
Good luck

Instead of walking to the parts rack every few minutes, each technician is followed by a robotized parts car that contains all the components for a single engine.

Germany, AMG plant where one man builds the whole engine.

Getting user feedback that we need some sounds for our robot. Specifically, sounds for:

- robot in motion
- robot with someone in the way
- someone moving too fast away from a robot and robot wanting them to slow down
- robot waiting and awake but not doing anything

Any ideas? Seems like everything to date in ag is back up alarms and beeps.

Don't limit yourself to single sounds. In dealing with factory automation over the years I've seen some people have success using music as signals (a certain tune means a certain thing). The varied notes in a tune give a better chance that even people with some hearing deficit can detect it. George Jetson car sounds are cool, but high frequency deafness is fairly common. Mid-high frequency noise pollution is also quite common in work environments. It is a lot like looking across a field. You may not pick up on something that should stick out, but if it moves you can detect it. It is basically the same way with sounds.

I would also suggest looking at lighting. We use a blue warning light on our forklifts. It projects ahead of and behind the lift so even if you aren't looking in that direction or the lift hasn't come around the corner you can see the light on the floor, telling you a forklift is approaching. It has saved my bacon a time or two when an inattentive driver comes sailing around a blind corner. You would think noise would be enough, but in a worksite with machines running and multiple beepers and buzzers going off, plus noisy tasks being undertaken you might not be able to pick it out from 10 feet away.

wow, very impressive.
could you show a pic of the lcd screen and operating controls?

The burro sure seems narrow and tipsy, it would fall over in our yard. It is very interesting technology.

At work, in use. In application not narrow not tipsy. Robust, 1000s of miles traveled autonomously, 1000s of hours of operation.
