The goal here was to create a as functional a Propeller robot as possible for less than $50. The Bluetooth capability pushes it over the $50 mark, but I thought it was a feature that was worthwhile for someone beginning in robotics. I was able to adapt a mini-BASIC to run over the Bluetooth connection which accepts BASIC programs like this one.
10 FORWARD 150
20 PRINT HCSR04
30 IF HCSR04 < 150 THEN BACKWARD 200
30 IF HCSR04 < 150 THEN RIGHT 250
40 GOTO 10
Program in BASIC via Bluetooth connection, wander aimlessly.
- Actuators / output devices: Two 5v Stepper Motors
- Control method: Semi-autonomous, Bluetooth
- CPU: Parallax Propeller
- Power source: 4-AA Batteries
- Programming language: Propeller Spin / BASIC
- Sensors / input devices: IR, HC-SR04
- Target environment: indoor
