Robot coprocessor

Post by skye » February 8th, 2016, 12:44 pm

I am working on a Mojo design that will act as a coprocessor for my ARM based robot. I plan to have it interface to an accelerometer/gyro to use as an IMU. With the FPGA I should be able to integrate as fast as the data is available. Right now on the ARM I am limited to about 200 Hz. The Mojo would also run the camera for obstacle avoidance. I am also thinking of using the RAM shield for telemetry data but storage may not be big enough.

I have broken this project up into smaller chunks. I am currently on step1 "Understand ISE".
Next will come:
"Simple TX UART" (debug)
"I2C Master" (Talk to gyros, ...)
"I2C Slave" (Talk to ARM)
"Camera" (Avoid red barrels in the Sparkfun AVC)
"Memory" (Log data to ram rather than the current SD card)

Sounds like a really sweet project!I'd love to hear about your progress.

I'm also living in Denver now so I'll be at SparkFun's AVC this year.
