Robots come in as many form factors as there are applications for them. Sizes range from massive industrial machines to tiny bots the size of insects. In the field of robotic human augmentation, a lot of focus is put on large exoskeletons that can make a person stronger. Now, a joint effort between researchers from MIT and the Rhode Island School of Design is bringing robotic augmentation in the other direction with a small robotic arm that’s worn like a wristwatch.
The platform is capable of that dexterity thanks to a series of customizable modules. A base module is placed on a wristband and provides power. The user can then stack various servo and sensor modules to build the robotic arm that suits their needs. Each module has its own ATtiny85 microcontroller, and the modules are chained together to communicate with I2C.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
