Assembling the Tinker Pi Robot for Microbit #tt13
Tinkerer: Lory Livezey
The Tinker Pi Robot is a modular learning platform that can be configured to run on any of the open source micro-controllers, such as Arduino, Raspberry Pi, and as we'll be doing in this tutorial, the Micro:bit.
What you will need
Step 1 - Attach the Castor to the Black Base
The castor, or third wheel, is attached to the bottom, using the screws in the bag marked
castor. The screws should be inserted in the colored piece, and run through and first hand-tighten the nut on the castor. Use a screw driver to tighten.
Step 2 - Attach the Motors
Place the colored bottom on the black bottom. Next, we'll attach the motors.
The two pieces that are the same snap onto the two notches on the outside edge. One of the two inner pieces has an "L" shape, the other is straight.
The bracket with the "L" shape should be inserted on the
left side, pushed down through the colored piece.
Flip the base over, and snap the side bracket in the notch on the side:
Slide the motor in between the black brackets. Slide the screw through. Hold the nut with your finger and tighten the screw with a screwdriver:
The straight bracket will slide down through the
Slide the screw through the motor and the two brackets, then tighten with a screwdriver.
Feed the wires up through the bottom layer:
Step 3 - Attach Bridges to Base
bridges hold the top layer to the bottom layer. Snap the bridges into the base layer, then use the screws in the bag labeled
bridges-- four screws are inserted from the base of the bridge, through the bottom layer, then a nut is first hand-tightened, then tightened with a screwdriver. You should have two screws left over for the next step.
Step 4 - Attach Top Layer to Bridges
Place the colored top against the black top and use the two remaining screws to attach the top layer to the bridges, using the center holes. Insert the screws through the top and hand-tighten the nuts underneath. Use your screw driver to tighten.
Step 5 - Assemble the Wheels
Snap the black tires onto the colored wheels. It works best if you start at the bottom and work your way up.
Insert the hubs into the wheels through the
outside of the wheel. The
inside of the wheel is flat, the
outside has the design. Screw the wheels into the motors.
Next, insert the wheels onto the motors:
Screw them on:
Step 6 - Assemble the Motor Board Snapee
The motor board snapee will allow you to snap the motor board into the robot. Insert the screw through the side with the snaps. Slide the nut on next. It has threads and won't "screw", but the nut is just there as a spacer to allow some air for the circuit board.
Snap the motor board onto the top layer of the robot.
Step 6 - Assemble the Micro:bit Case
Place the Micro:bit onto the back piece.
Then snap the face onto the back:
Plug the Micro:bit into the Motor Board.
Step 7 - Attach the Breadboard to the Breadboard Snapee
Peel the adhesive off of the breadboard and apply it to the snap. Make sure you line this up accurately, or the other pieces may not fit right.
Plug the breadboard power supply into the breadboard:
Plug Red Wire (+) and Black Wire (-) into the breadboard's (+) and (-) row:
Plug in the 9V Battery:
The breadboard power supply can supply either 5V or 3.3V to either side of the breadboard. We will need 5V to power the Motor Board, so whichever side you plug the power wires into should be set to 5V:
Step 8 - Wire up the Motor Board
The breadboard snap will fit into the bottom level of the robot -- there are 2 slots sticking up that hold the 9v Battery in place:
Next, plug the red and black wires from the breadboard into the
- on the Motor Board:
Plug the motors into the Motor Board as shown below -- red, black, black red. If you get these mixed up, you won't hurt anything. Your wheels may turn the opposite way that you would expect.
Step 9 - Ready to Program!
You have successfully assembled the Tinker Pi Robot for the Micro:bit. The next step will be to program it, or if you can do that without instructions, you can download the two hex files here.
