WolfBotz Mini Sumo Robot – IEEE CEFET/RJ

WolfBotz Mini Sumo Robot – IEEE CEFET/RJ

Robot and Team Name

The robot’s name is Maiara from WolfBotz which is part of the Student Branch IEEE CEFET/RJ

When you build? And Duration of progress

We started building in January 2019 and finished in May 2019, it took 4 months of work. However, it’s continuously upgraded and improved.

What was the hardest part you achieved?

The circuit board had more problems due to its complexity

Robot’s Total Weight & Dimensions
Almost 500g.

Maximum speed it can achieve
The robot can achieve around 1.2 m/s

Which batteries it uses?
We use a Lipo Battery 1000 mAh 4s 65c Turnigy Graphene Drone Aero.

Motor models and reduction system?
We use a fingertech 33:1 motor

At your robot what is more stronger, torque or speed?

Also please explain your electronics. Which Microcontroller system is used? What is compliementary circuits like regulator boards, motor drivers or other sensors…
We use a regulator, one motor driver, a ICSP connector and PIC as microcontroller. The project also counts with Fingertech 33:1 motor, JS40F sensors and ML1 micro line sensors. Besides that, all the electronics are connected on the same board.

How did you made your PCBs, custom made or factory production? Or ready boards?
Our PCBs were made by factory production.

How many sensors robot uses? What is Edge sensor and Opponent sensor Features?
The robot uses 7 sensors, among them, 5 JS40F JSumo sensors for opponents and 2 ML1 JSumo line sensors for the edge line.

Are there any tournaments that robot competed? Any degrees?
Yes. In 2020, until now, the robot has competed on IronCup. In 2019, it competed on IronCup, Bosch, Salão de Robótica and Smile. It won first place on Smile competition in 2019.

What do you plan for future on that robot?
We are willing to an even better robot, to achieve higher positions on the next competitions. Besides that, we work hard to improve the robotics visibility in our country and hope to get the chance to appear on television as we once did.

If any JSumo product helped you please declare
We used five JS40F JSumo sensors and two ML1 micro line sensor that were of great help.

Parts List of Robot

One motor driver, two wheels, one machined steel base, a voltage regulator, seven JSumo sensors, a start and a reset button and a Chassis machined by Transcional.
