Haha... This reminds me of Double Rainbow. Great job, guys!

gudjob,but i only use PIC16f84a and build in 3hours.gud job all of you.nice work..may all of u success.

That was very cool. >.> Robot Wars time?

It seems to me you are underestimating this project. Implementing the controller was 2 days work for us(may be this is what took you guys 2 weeks!) but we had to machine each mechanical component by ourselves, make our own data aquisition PCB from scratch using a CPLD to interface to the ISA bus of the industrial PC.

[raminsaheb]

The power management was also an issue as the computer needs 3-5amps at 5 volts (try finding a power supply which feeds from a battery that does that!). As the voltage of the battery drops all the controller parameter change which have to be dynamically adjusted. Additionally, you can re-program the controller on the fly a through your wirless LAN connection.

This is nice, check out our "Proyecto Equilibrista Electronica ITCR", it is similar to this one.

8 months?? A PID Inverted pendulum would take less than a day to build based on a 16F684 and AN964

[raminsaheb]

Try implementing a PID on a Pentium 3 industrial PC (mounted on the robot) interface that to a custom made DAQ and write five 40 page detailed reports to convince your supervisor and you'll understand how short 8 months could be ;)

[tsport100]

You need to tell your supervisor he's just made you spend 8 months reinvent the wheel. Not only does a PIC do this without a DAQ (let alone a custom one) but it'll also run the H bridges. A group of high school kits built a Home made Segway copy over a couple of weekends.

@raminsaheb why a Pentium 3?

I really don't understand. Doesn't your supervisor know yet that MCUs exist?

After all, is it a programming work or robotics?

You'd need a real hard CPU for VERY complex robotics projects, like ASIMO, etc...

I made my own quite stable mini segway in just 2-3? days, and I'm not a programmer nor electronics designer (YET)!

[raminsaheb]

@TitanaMaster the robot is running matlab xpc tagret which is resource hungry. The plus side is that you can easily implement your controller using blocks in simulink in a matter of minutes (not days). This makes it an ideal robot for classrooms where you teach students about controllers and make them implement controllers for it. See other vids.

ha very nice.

[ideegeniali]

Congrats, but So what? A 20 years old guy can do a balancing robot in 2 weeks, smaller, faster, cheaper than that...

[benhumpert]

congrats!!

[Anniebmice]

Way to go guys!!! Congratulations on your achievement!! Best of luck to you!

[pepperluig]

Woow Congratulations!! That's pretty impressive

[raminsaheb]

Cooool
