Simple One-Servo Walker
« on: September 29, 2015, 07:04:35 PM »
From upcoming part three of a series in SERVO magazine. Passive legs let the bot fall forward.

Thanks, it's a bit monolithy sitting still. In motion, it's somewhere between TARS and the drones Huey, Dewey & Louie.

Speaking of TARS, I have to get back to this one:

Pretty cool, erco.

Hmm... Technically, it's a quintuped? Well done. I wonder if it could move a little smoother without the pauses between servo movements.

Very nice one motor walker.  I'm a fan of this style of minimalism.  Beyond keeping the costs and build complexity down, you keep both weight and power requirements under control.

I keep subscriptions to both Servo and Nuts & Volts magazines.  I'll be looking for your write-ups.

Wow! This little guy is quite responsive in it's light tracking ability. I have a love of simple bots and also single motor/actuator robots, this fits both categories. Nice work! It looks like I need to restart my subscription to Servo ASAP.

What do you use the numeric display for on the bot? Also do you have a close up of the leg mechanics to share or will that be in Servo magazine?

Construction is pretty forgiving, you can see some details at https://www.youtube.com/watch?t=142&v=_99Bq5mOFDs

That 3-digit LED display is a $1 Ebay DVM. It keeps resetting when the robot walks, the alkaline batteries can't keep with servo current demands. It's useful for monitoring analog sensor values, as shown at https://www.youtube.com/watch?v=8gotiXIKFV8

A more interesting use of the onboard DVM is as a general numerical display by PWMing calibrated values to it. Cheapest LED display in town. https://www.youtube.com/watch?v=G4U6-0F0_Lw   and   https://www.youtube.com/watch?v=rfnpWDJ1R8E

Excellent, I just heard from a guy in the PICAXE forum who built this bot. Nice to see that it wasn't hard to duplicate, that was my goal. Hopefully there will be more, construction is detailed in the next SERVO magazine (November).

Part three of my PICAXE series is in SERVO's November issue, featuring this little bot. The first half is online at http://servo.texterity.com/servo/201511/?folio=68&pg=68#pg68

Speaking of simplicity, I found another "Walking Breadboard" on Youtube. It has trouble getting traction. Looks like he has some pivoting feet on the servo arm "legs". IMO they need to grip one way and slide the other, or else use ratcheting wheels.
