With modularized mechanical structures, electronic modules, and Arduino programming, I made this aulminium alloy robot with Makeblock. (Now they are on Kickstarter, and many super-value kits are available.)
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Tools
Tools needed: Screw drivers and a plier.
Step 2: Prepare Motors
The tank is two motor drived. So I first need to make two motors possible to be installed onto the beam structure.
First solder the wires and the connectors to the motor.
Then add the motor bracket.
Step 3: Prepare Wheels
Two 90T wheels with shaft connector needs to be installed onto the motors.
Two 90T wheels and twelve 66T wheels with flange bearing are needed.
Step 4: Prepare All the Neccessary Parts
Beams with different length
Step 5: Make the Frame Structre
Connect two beams with a plate to make a long beam.
Step 6: Install Two Motors
Step 7: Install the Wheels
90T wheels were installed on the end, while the 66T wheels installed in the middle.
Step 8: Fasten Screws
Make sure all the wheels fastened.
Step 9: Add the Track
The track is chainable, so that I can change the length per needed.
Step 10: The Tank Subbase Is Ready
The basic tank is ready. if you add the drivring circuits and a Microcontroller, it is controllable.
Step 11: Prepare the Robot Arm and Hand
I also prepared the robot arm and hand for the tank.
Step 12: Install the Arm
The arm was driven by a geared DC motor with timing belt. The servo can be used to control the robot hand.
Step 13: Prepare the Electronic Moddules
I also prepared the Arduino compatible electronic modules. They can drive 3 DC motors, two servos, and be controllable remotely by infrared controller.
Step 14: Install the Hand and the Electronics
Step 15: Done
I haven't finished the progrmming and test. Once finished, more videos will be posted here. Just keep an eye on it.
