My new sumo robot, ıt took 6. degree ın Turkey competitons. We have better sumos..

Made ın Turkey, Istanbul. It uses 2 maxon 150 watt motors. 7 Pepperl fuchs sensors. For motor control I used sabertooth 25 x2. But It was not enough.


Technıcal Specs:
Voltage 25V (6 cell lipo)
Weıght: 3kg
Speed 1m/sec
Body: Laser cut Alumınıum
Wheels: only two wheels.
Sensors: 1 meter dıstance Industiral sensors.
Gear reducton: 7,2:1
Magnets: A lot of... Pulling force 40-50kg.

Good use of Duct Tape!

What are Pepperl fuchs sensors? Industrial proximity sensors?

Yes Pepperl fuchs sensors have only 0.5 ms response time.



And autodesk Assembly

I don't do facebook, sorry.

That's pretty fast!

What is the part number for the Pepperl fuchs sensors? Just curious.

Sensor model ML100-8-1000-Rt. Diffuse type.

They are threaded for easy mounting. very small red light sensors not infrared because red light is cool:)

I'm not that great with math, but if the bot moves 1 meter in 1 second, with a 0.5mS response time the sensor should be able to check 2000 times in the 1 meter traveled. Or in other words it can check for an opponent every 0.5mm. For a comparison the Sharp GP2D12 has a 39mS response time and it can only check for an opponent 25.6 times in the one meter traveled, or every 3.9cm. You might think the Sharp would do ok, but when you consider the fact that the opponent is also moving at a fast pace, and the fact that you must filter out spurious possibly false detections, it's just too slow.

I had to position my floor-looking IR sensors about an inch forward of my front caster on my ASB-13 'bot. That surprised me. I'm also sampling at a 100mS rate. I'll have to clock it and see how fast it moves. That might explain part of my slower response.

Great! high quality robots( like Fusion) needs high quality sensors ( like ML100-8-1000-Rt) sharps are so slow for japanese style sumo robots

its our robot batusay,
its uses five omron sensors which had 1 ms response time and 2 maxon 150 watt motors
