TIRSLK-EVM: TIRSLK-EVM

Part Number: TIRSLK-EVM

HI,

I built the robot and completed the Lab module 5 successfully. However, when I was going the Lab 6 and downloaded the program, one of the batteries overheated and exploded with acid leaking out. After that the chassis board stopped working. After I put new batteries on, irrespective of whether I turn the chassis on using the switch the chassis board gets turned on with the blue LED indicating power always on. I checked the voltages, I get the 5V and the 3.3 V. I am not able to measure the current since I do not have the current measuring multimeter.

Please advice on what diagnostics I can do. 

Thanks,

Vishnu

  • Hello Vishnu,

    Thanks for choosing TI-RSLK MAX robot. I am sorry you ran into some issues.

    Please confirm where  the unit was purchased from. Also if you are referring to the lecture modules and all documentation ( USER Guide has all necessary information)

    - Please confirm the batteries used 

    - Also can you send a photo of the robot, with the TI LaunchPad on the robot, please see RSLK MAX  USER guide for correct configuration on the position of the LauchPad jumpers.

    If you are seeing the 5V and 3.3 V on the TI chassis board looks like your TI chassis  board is OK, do you see any damage on the chassis board?

    Please check each board separately - MSP432 LaunchPad can be tested per Lab 1&  2, you will need to measure current, voltage of the LaunchPad.

    I hope we can recover the robot.

    Thanks 
    Ayesha

     

     

  • Hi Vishnu,

    Be sure to inspect for physical damage. If you noticed any burning smell or bubbles on the power regulators this could indicate something got burned out. Hopefully the damage was just to the battery and not the circuit. 

    You should be able to test by going back through the previous labs. You can also use the debugging tool at www.ti.com/rslkdebugtool

    You want to isolate first that the LaunchPad is working correctly. Verify it is detected when plugged in to the PC and you are able to flash programs to it from CCS. Then next you can start testing with the robot. 

  • Hi Mark,

    Thanks for the response. I was able to clear out the battery acid from the chassis board. I did do some basic diagnostics. It does seem to work now. I will be monitoring the voltage and current closely so that the problem does not reccur.  Thanks,

    Vishnu

  • Hi Vishnu,

    That's promising news. Glad you are able to recover the robot and continue. Thanks!
