SERVO WIRE CONNECTIONS

Make sure to connect the Hummingbird Duo Controller to the power supply when using the motors of servos: USB alone does not provide enough power to run these components.

Gear MotorAn electric motor with speed control that can rotate in either direction - connects to the yellow terminals or the orange terminals.

Servo180 degree motor with controls for specific angular positions - the servo is the only com-ponent that connects to the Hummingbird Duo Controller through a grid of metal posts.

Leg Adapters

Gear Motor Brackets

Soft Arms

Gear motor brackets can be used to connect gear motors to the motor bases.

Leg adapters can be used to connect the c-shaped legs to the gear motors.

1) Screw leg adapter into gear motor using center hole

2) Screw c-shaped leg onto leg adapter using two outer holes

1) Slip the bracket over the

gear motor

2) Screw the bracket into

the motor base

Soft arms can be connected to the motor bases to make robots with greater stability.

1) Screw the soft arm into

the motor base

Servo Gripper Mount

The servo gripper mount can be used to connect the servo to the motor base in different ways. You can attach it flat on the motor base or use the right angle mounts to attach it vertically.

1) Screw the servo into the servo gripper mount

2) Screw the servo gripper

mount into the motor base

directly

The soft gripper can then be attached to the servo so that you can control the gripper opening and closing by programming the servo.

(see pg. 9: Building a Gripper)

3) Screw the right angle mounts into the motor base

2) Screw the right angle mounts into the servo gripper mount

Motor Bases

The motor bases can be used to help connect all pieces together to make one whole robot. You can use one motor base or connect the two motor bases together to attach more pieces to them.

You can connect the two motor bases together to make a bigger robot with the motor base connectors

WHAT ATTACHES WHERE?

You can connect the Hummingbird DUO to the bottom of the two motor base

PROGRAM Programming Gear Motors

7

Programming Gear Motors

If you are only using one or two gear motors then connect them to the orange motor pins.

Gear motors spin 360 degrees and can be used with the C-shaped legs to make your robot move.

If you are using three or four gear motors then connect two of them to the orange motor pins and two of them to the yellow pins.

If you put gear motors in the orange motor pins then you want to select the orange pins.

If you put gear motors in the yellow motor pins then you want to select the yellow pins.

* positive speed makes the motor move forward, negative speed makes it move backwards

* There is only positive speed so if you want to make these motors move the other way then you have to switch the wires in the - and + yellow pins

PROGRAMProgramming Servos

8

Programming Servos

Servos spin 180 degrees and can be used to make the gripper open and close.

You can connect up to four servos in the servo pins. Make sure the black goes on the - pin, the red wire goes on the + pin, and the yellow wire goes on the S pin.

Select which servo ports you put servo motors in. Then you can program what degree you want your servo to turn to. The speed of the servo is always the same, it can’t be changed.

BUILD Gripper

Building a Gripper

Build a gripper to help your robot pick things up.

Materials- Hummingbird DUO- 1 servo (from Hummingbird kit)- Lever servo attachment- Servo gripper mount- 2 gripper extensions- Soft gripper- Motor base (if needed)

2) Screw servo into servo gripper mount (see pg. 5 : Connecting the Servo Gripper Mount)

1) Screw lever servo attachment to servo

3) Connect gripper extensions to end of lever servo attachment, putting a washer between them

What kinds of animals do you know that can grab objects like this gripper?

4) Screw the gripper extensions into the first holes of the soft gripper, one on top and one of bottom of the soft gripper.

6) If needed, attach gripper to motor base (see pg.5: Connecting the Servo Gripper Mount)

8) Connect servo to Hummingbird DUO (see pg.3: Connecting Motors)

9) Program the servo (see pg.8: Programming Servos)

7) If needed, attach Hummingbird to motor base (see pg.6: Connecting the Motor Bases)

5) Screw one of the second holes of the soft gripper into the servo gripper mount.
