At April 2013 I made new magnetic sumo robot. Features: 2 Maxon RE35 Dc Motors 2 Omron E3z-D62 Sensors 3 Keyence PZG-41 Sensors. 4 QRE1113GR Edge Sensors. Custom made motor controllers 2 Wheeled Design. A lot of neodmiyum magnets. Blue pcbs are custom built motor drivers. At the center Pic16F877 Carrier board with SMPS voltage regulator. Here, video explains lots of things. 😉
Last year I designed some sumo robot controller circuits. All components (Motor drivers, voltage regulators, Arduino) in one board. Firstly I made some test with breadboard. This wasn’t last design. I doubled mosfet transistors at last design. Last through pin design. It was like an art to make this board. I used at Shadow sumo robot. After I used smaller SMD motor controller designs. Also Design’s one fault is not having optocouplers (Very big Fault..)
How to Design & Make a Good Sumo Robot In this article, I will share my sumo robot design and build secrets. Firstly we are starting with sumo robot parts. Please click the bottom image for bigger visual, in that article I will go deeply at each section for sumo robots. We can divide sumo robot to 3 subdivision: Mechanic System – Structure Electronic System – Organs Software system – Robot’s spirit Firstly we starting mechanical System. The mechanical system covers motors, gearing, wheels and robot’s [...]
Cellat (Executioner) Sumo Robot (Old 2008 Year Project) Actually it has three plexiglass plane. İt uses 4 Maxon motors, They rated 48V!! Yess:) Motors are weighing 400gr ea. It’s wheels are 6cm diameter Neoprene formula car tires.. Motors have high speed about 638 rpm and 14 kg-cm torque. I’m was using 36! NiMH AAA cells. (It was a long times ago before li-po batteries…) (more…)
Technical Specs: Voltage: 25V (6 cell lipo) Weight: 3kg Speed: 1m/sec Body: Laser cut Aluminium Wheels: Only two wheels. Sensors: 1 meter distance industrial sensors. Gear reduction: 7,2:1 Magnets: A lot of neodymium (NdFeB) magnets… Pulling force 40-50kg. It competed at Turkey 2011 competitions. Watch below. Pepperl fuchs sensors have only 0.5 ms response time. Robot’s System: And Autodesk assembly pics. All project has been designed with Autodesk Inventor. Motors: Maxon RE40 Model motors were used. They are big, beefy motors.
Deep Impact Sumo Robot [dropcap color=”color-default” font=”arial” style=”normal” size=”ltt-2em”]I[/dropcap] watched videos of how to develop the project, Japanese sumo robots as fast as it can be extremely sharp turn in the thought of how make. And Deep Impact was born:) it has 2 edge contrast sensor, 2 ultrasonic sensor and 6 infrared sensors. It uses six Faulhaber dc gear motors. Robot Body The body of the robot must be big to take 6 dc motor and big enough to hold 12 cell battery and [...]
