tv: Measuring Battery Use

Season 3 : Ep. 12 | 3:46



In this episode I use the ACS714 Current Sensor to attempt to measure battery use of my dogbot leg. But will it work?

tv: Solutions for Wire Flexibility

Season 3 : Ep. 11 | 6:49



This episode reviews some of my favorite viewer contributed solutions to my wire flexibility problem. Thanks to all who contributed their ideas!

tv: Measuring Wire Flexibility

Season 3 : Ep. 10 | 10:30



I noticed a trend in the comments from the last video. I got a lot of comments about using a smaller gauge wire. In this episode I test the flexibility of 30 gauge, 26 gauge, and 26 gauge shielded wire. Thanks for all the feedback from the last episode! In the next episode I'll dive deeper into that feedback.

tv: A Problem of Flexibility

Season 3 : Ep. 9 | 3:13



I need your help. I'm stuck! I need a way to receive information from the DogBot foot without restricting it's movement. Any ideas? Please leave a comment if you have any ideas!

Here are the background videos leading up to this one:

tv: How to Wire a Robot

Season 3 : Ep. 8 | 9:18



In this episode we consider what goes into wiring a robot. We look at a cheap source of 24 gauge wire, look at standardized connectors, and go over wire organization.

tv: Robotic Leg Assembly

Season 3 : Ep. 7 | 3:23



In this episode we assemble the latest version of the dogBot leg!

tv: Servo Animation

Season 3 : Ep. 6 | 4:18



In this episode we plug in our hacked servo. This hack allows us to not only tell the servo what to do, but also record movement. One application of this is to record a manual motion while the servo is disabled, then enable the servo and play the motion back! - Season 3 : Ep. 6 For more episodes, visit: http://tv.onshoulders.org
