The Talon Claw/Grabber is an accessory for the the Bit:Bot robot, allowing the robot to grasp small objects using standard servo code in MakeCode for the micro:bit. Specific code has been added to the BitBot package to control this Talon directly.
There's no soldering required. Just attach few screws and you're ready to go.
Included are 3 PCBs that make up the Talon, a metal gear servo, and all the screws and pillars you will need. Also included is a Pimoroni spanner widget to help tighten the nylock nut.
You will require an Angle:Bit or similar to allow access to the microbit once this is fitted
Note that the ultrasonic add-on cannot be fitted at the same time as they use the same connections.
See the 4Tronix blog entry for assembly, setup and usage instructions.
Note: Bit:Bot and micro:bit not included, but available separately.
