A system can use electrical signals from the body to control infrared appliances such as a television. Electrodes capture signals produced by blinks or muscle movements, Neuro PlayGround Lite detects them, and its ESP32-based hardware sends the corresponding infrared remote command.
The Neuro PlayGround Lite can measure small biopotential signals including EEG, EMG, ECG and EOG. In this example, the practical control is less science-fiction mind reading than turning eye and muscle signals into new physical input buttons. The project was demonstrated by Upside Down Labs.
Instead of looking for the remote, you first attach electrodes to your forehead. It adds a few steps, but turning a blink into a channel button still feels pleasantly futuristic.
Bentobot was built so online friends could control real combat robots from phones and computers anywhere in the world. Thomas Nguyen created three small Raspberry Pi Zero 2 W-powered machines with drive motors and separate weapon motors, including flippers and spinning weapons. Viewers could join live streams, receive access through an app and immediately fight physical robots in the arena. Nguyen even created a lightweight custom language to reduce control latency. Instead of simulating robot combat online, the network ends at actual machines hitting each other.
Most online games keep the damage virtual. Here, the internet connection ends in two real robots smashing into each other.
