Wireless controller
The new wireless controller was designed and 3D printed. The new controller has better connectors that connect wires from the buttons and the switch to the transmission circuit of the controller. The controller was designed considering that the following features should be reflected in the user interface system:
1. The controller should have all required input commands (4 buttons for planar movement, power switch, power acknowledgment LED, CHARGE button, JUMP button).
2. More room for the transmission circuit of the controller.
3. A separate battery compartment so that the complete circuit is not exposed while changing batteries.
4. The edges of the controller are curved for user safety. The controller has a better grip for human hands (inspired by the existing video game controllers).

Second prototype of the wireless remote controller
Today we demonstrated the second prototype of the wireless controller. The figure below illustrates the wireless controller which has been designed considering the requirements of the user interface subsystem. The controller allows user to execute any command in at most two steps. It has the following controls:
Today we demonstrated the second prototype of the wireless controller. The figure below illustrates the wireless controller which has been designed considering the requirements of the user interface subsystem. The controller allows user to execute any command in at most two steps. It has the following controls:
1. Planar motion controls – Forward, backward, rotate left, and rotate right
2. Charge button – Compresses the fiberglass spring and brings the robot to ready-to-jump position.
3. Jump button – Releases the spring to make the robot jump
4. On/Off switch – Switches the controller on or off
5. Power LED – Acknowledges that the controller is switched on

First prototype of the wireless remote controller
The figure below is a picture of the wireless controller chassis fabricated for the jumping system. The controller suffices all the system requirements for the design of the user interface of the jumping toy. The circuit of the controller was powered using four NiMH batteries which supplied 4.8V. The controller has an On/Off switch to power the wireless controller. The user can set the jumping power using the black knob connected to a potentiometer and command the system to launch using the launch button.

Testing circuit of the wireless remote controller
Today we demonstrated the successful communication between two XBee modules. We implemented a controller and a receiver to imitate the actual remote controller of our robot and the receiving module on our robot, respectively. The controller consists of a XBee, a XBee Explorer, a potentiometer, a button and a LED; the receiver consists of a XBee, Fio v3 microcontroller, two LEDs and a servo motor. On the controller end, users can adjust the potentiometer to a desired position and press the button to send the information to the receiver. Whenever the button is pressed, the status-indicating LED would be lit and the analog value of the potentiometer would be converted to a digital signal through an AD Converter on XBee and then be sent to the receiver. On the receiver end, two status-indicating LEDs were used, one indicating the receiver has received a signal and the other indicating the opposite. If the packet is received by the XBee on the receiver end, it would be deciphered by the microcontroller then converted to signals that control the LEDs and the servo motor, which rotates according to the potentiometer value on the controller end. The picture below shows the setup.
