Sphero BB-8
The Sphero BB-8 is a toy robot from Sphero that is controlled using Bluetooth LE. For more information, go to http://www.sphero.com/bb8
How to Install
go get -d -u gobot.io/x/gobot/...
How to Use
package main
import (
"os"
"time"
"gobot.io/x/gobot"
"gobot.io/x/gobot/platforms/ble"
"gobot.io/x/gobot/platforms/sphero/bb8"
)
func main() {
bleAdaptor := ble.NewClientAdaptor(os.Args[1])
bb8 := bb8.NewDriver(bleAdaptor)
work := func() {
gobot.Every(1*time.Second, func() {
r := uint8(gobot.Rand(255))
g := uint8(gobot.Rand(255))
b := uint8(gobot.Rand(255))
bb8.SetRGB(r, g, b)
})
}
robot := gobot.NewRobot("bb",
[]gobot.Connection{bleAdaptor},
[]gobot.Device{bb8},
work,
)
robot.Start()
}
How to Connect
The Sphero BB-8 is a Bluetooth LE device.
You need to know the BLE ID of the BB-8 you want to connect to. The Gobot BLE client adaptor also lets you connect by friendly name, aka "BB-1247".
OSX
To run any of the Gobot BLE code you must use the GODEBUG=cgocheck=0
flag in order to get around some of the issues in the CGo-based implementation.
If you connect by name, then you do not need to worry about the Bluetooth LE ID. However, if you want to connect by ID, OS X uses its own Bluetooth ID system which is different from the IDs used on Linux. The code calls thru the XPC interfaces provided by OSX, so as a result does not need to run under sudo.
For example:
GODEBUG=cgocheck=0 go run examples/bb8.go BB-1247
Ubuntu
On Linux the BLE code will need to run as a root user account. The easiest way to accomplish this is probably to use go build
to build your program, and then to run the requesting executable using sudo
.
For example:
go build examples/bb8.go
sudo ./bb8 BB-1247
Windows
