Autonomous magnetic robots that discount christian louboutin shoes uk traverse vertical surfaces

The robots are outfitted with several light sensors, allowing them to respond to simple user interactions.My implementation supports 3 robot which can be changed by covering the topmost light sensor:

Red robots move fast, going towards objects(Such as human hands or other robots)

This instructable details my first prototype.In the christian louboutin shoes uk sale future i plan to build in more complex, autonomous behaviors.I will use these robots to engage people in public spaces such as elevators or hallways.In doing so, i hope to facilitate creative interaction between people and technology in mundane, everyday settings.

SErvos are an easiEr altErnative to using dc motors such as hobby or gear motors.They feature a built in gearbox and drive circuitry.Say a sErvo costs 10 bucks.If you get a hobby motor for $1, you still need gears and drive circuitry.The common l293d dual buy louboutin shoes uk motor drive chip(Aka dual half bridge)Costs about 5 bucks.Not to mention this requires more pins of your microcontrollEr(Like arduino)Vs.A sErvo only requiring one.A gear motor(With a built in gear box)Will typically cost more than a sErvo itself.So.SErvos are quick, cheap(Er), and are generally more convenient.In a project like this, there's no space to build 2 gearboxes with about a 120:1 gear ratio each.It also leaves a lot less room for error. I can't tell you how many robots I've built whEre the fatal Error was an evErSo tiny flaw in the gear train.
