  • Ultrasonic Distance Sensor (Static) CrumbleBot Addon (BOTSONIC)
    Static Ultrasonic Distance Sensor for CrumbleBot

    This a simple, screw-together addon for all versions of CrumbleBot. Using the 2 mounting holes at the front, together with the power supply extension pieces (included) you can easily add distance sensing to your CrumbleBot.

    Using a single Croc Clip for the sensor reading and Crumble Software 25.2 or later, you can check if the CrumbleBot is about to hit an obstacle then avoid it if necessary.

    No soldering is required, and the kit can be assembled in a few minutes using only a small philips (cross head) screwdriver

    Contents:
    • Ready assembled ultrasonic PCB
    • Red positive power extension
    • Black negative power extension
    • 2 x M3 15mm hex pillars
    • 6 x M3 6mm screws
    • 2 x M3 nuts

  • Ultrasonic Distance Sensor (Panning) CrumbleBot Addon (BOTSONPAN)
    Panning Ultrasonic Distance Sensor for CrumbleBot

    This a simple, screw-together addon for all versions of CrumbleBot. Using the 2 mounting holes at the front, together with the power supply extension pieces (included) you can easily add distance sensing to your CrumbleBot.

    This version of the kit includes a servo to allow you to move the ultrasonic sensor left and right, using the inbuilt Crumble software commands.

    Using two Croc Clips, one for the servo and one for the for the sensor reading, as well as Crumble Software 25.2 or later, you can check if the CrumbleBot is about to hit an obstacle then avoid using a more sophisticated algorithm than just a static (non-moving) sensor. Of course, you can simply not move the sensor and use the simple software shown in the static sensor listing

    The program shown above detects an obstacle within 15cm, then looks left and right to see which direction has the closest obstacle. It then reverses out of the way of the current obstacle, before turning towards the direction with most space to move.

    No soldering is required, and the kit can be assembled in a few minutes using only a small philips (cross head) screwdriver

    Contents:
    • Ready assembled ultrasonic PCB (moving)
    • Ready assembled servo PCB (static)
    • Servo, complete with various fixings
    • Red positive power extension
    • Black negative power extension
    • 2 x M3 25mm hex pillars
    • 6 x M3 6mm screws
    • 2 x M3 nuts
    • 4 way female-female 10cm cable to connect the sensor to the static servo PCB

  • Adafruit Triple 3-Axis Accelerometer ADXL335 (ADA163)
    Adafruit updated their triple-axis accelerometer to now have an on-board 3.3V regulator - making it a perfect choice for interfacing with a 5V microcontroller such as the Arduino.

    This breakout comes with 3 analog outputs for X, Y and Z axis measurements on a 0.75"x0.75" breakout board. The ADXL335 is the latest and greatest from Analog Devices, known for their exceptional quality MEMS devices. The VCC takes up to 5V in and regulates it to 3.3V with an output pin. The analog outputs are ratiometric: that means that 0g measurement output is always at half of the 3.3V output (1.65V), -3g is at 0v and 3g is at 3.3V with full scaling in between.

    Fully assembled and tested. Comes with 8 pin 0.1" standard header in case you want to use it with a breadboard or perfboard. Two 2mm (0.08") mounting holes for easy attachment.

    The XYZ filter capacitors are 0.1uF for a 50 Hz bandwidth
