Welcome to the JECCbot_mini wiki!
The JECCbot mini is an outdoor robotics platform intended for participation in contests like Robotem Rovne (http://kufr.cz/), Roboorienteering (http://robotika.vosrk.cz/roboorienteering/index.php) or Robotour (https://robotika.cz/) but also for general robotic experiments. It has the size to be able to drive on streets, ways and grass and to get over small obstacles like stones.
The robot has several mounting positions for controller boards and supports the following footprints (layout of mounting holes)
- Arduino Uno, Arduino Leonardo, ...
- Arduino Mega
- ST Nucleo Boards
- Raspberry Pi Model B
-
print the main chassis and the rear chassis with a 3D printer.
-
connect the main chassis with the rear chassis using four M6x16 screws and nuts. There are undercuts to hold the nuts.
-
mount the roller wheel on the rear chassis using four M6x12 screws and nuts. Choose the holes which fit best to your roller wheel. There are undercuts to hold the nuts.
-
mount the gearmotors with four M3x8 srews each
-
mount the wheeladapter into the wheel
-
mount the wheel with adapter onto the motor shaft
-
mount the On/Off-switch on the top left side
-
mount the emergency button on the top right side
-
mount the 8 mm M3 distance bolts for the arduino boards with six M3x8 screws. alternative mounting possibilities for electronics are listed below.
-
mount the arduino board on top of these distance bolts
There are several mounting positions fro electronics on the JECCbot mini. The relevant holes are colored in red.
There is a mounting position for one Arduino Uno or Mega on the top side of the robot. Use six M3 screws and nuts with distance bolts.
There is an alternative mounting position for one Arduino Uno or Mega on the bottom side of the robot to keep the top side clear for other boards. Use six M3 screws and nuts with distance bolts.
There is a mounting position for one Raspberry Pi Model A or B (the big one) on the top side of the robot. Use four M2.5 screws and nuts with distance bolts.
There is a mounting position for one Adafruit 9-DOF Absolute Orientation IMU Fusion Breakout - BNO055 (Adafruit 2472) on the top side of the robot. Use four M2 screws and nuts with distance bolts.
There is a mounting position for one Adafruit Ultimate GPS Breakout - 66 channel w/10 Hz updates (Adafruit 746) on the top side of the robot. Use two M2 screws and nuts with distance bolts.
There is a mounting position for one DJI Naza-m V2 GPS receiver on the top side of the robot. Use four M3 screws and nuts.
There are several mounting holes reserved for expansion on the top side of the robot. They have a grid of 25 mm x 50 mm. You can mount some standard sections on them Use M6 screws and nuts. There are undercuts to hold the nuts.
