Arduino Compatible Brushless controllers from this project https://hackaday.io/project/165217-brushless-actuator-arduino-compatible with multi-turn absolute magnetic encoder. Beaded string drive (Vertical Blind cord) in four corners of the room. Claw uses the RC servos with the electronics removed and replaced with a custom triple H-Bridge Driver, good current feedback and SAMD21 running an Arduino compatible controller. Visual Studio .Net application runs the show. RS485 comms to the Brushless Actuators and Bluetooth comms to the thee servos. The claw is battery powered.Stuffed animal objected detection using Maixduino and the OV2640 camera module. Machine learning requires multiple images of the same object taken at different angles with different backgrounds. My daughter has over 200 stuffed toys, so her room can get a little messy. The pla
New Maixduinos RISC-V AI and machine learning dev kits arrived yesterday but shipped with the wrong camera. Swapped out camera from ESP-CAM, loaded the demo and it can detect supposably 1000 items. It does an ok job. Lighting is important. Object is Stig’s helmet.
Now to train it on stuffed toys to complete the room cleaning robot.
This is my daughter's idea after getting frustrated/losing at Timezone's claw machines. She helped with the wiring, installation and setup. Thanks mini-maker Sienna.
Xbox controller is modified and the pot signals go into a Sparkfun's SAMD21 dev board which sends pot positions via USB to the Visual Studio .Net app.
The motors are limited to about 2 Watts (kid mode) . 0.5kg counter weights keeps the beaded cord on the pulley without skipping. The absolute encoder with multi-turn software counter keeps track of the cord's length.
She has some pretty condescending thoughts on how to improve the current design. But it's such a great daddy-daughter project.
This is the spare room (old nursery). The claw moves to one of the upper corner when not in use.
