TIRSLK-EVM: TI_RSLK MAX

Part Number: TIRSLK-EVM

After finishing building the robot using the steps from TI's website for the TI-RSLK MAX construction guide, I experienced some issues with the product and believe it is because it came defective. After using the TI-RSLK debug software on TI's website I found that only the 2nd and 6th bump sensors were functioning. I also found that the right motor would not rotate and spin the wheel. The encoder would also not increase as I increased the speed on the left motor. I took it all apart, tried a different right motor, a different set of bump sensors, and the same exact issue occurred even after ensuring all the components were connected properly. I believe that I need a replacement kit for this product.

    Hi Shreyas,

    Thanks for the post and video description. That bump switch issue is a mystery as there isn't much that can break in that part of the circuit. Did you confirm the four pins of the bump switch are aligned to the four connector headers. There is a small chance they got mismatched by one pin, but I don't think the behavior you demonstrated reflects that. If those are properly connected than the issue might lie with the LaunchPad pins themselves having an issue. So on the LaunchPad you may want to confirm it is attached to the chassis board properly and all the pins are lined up correctly when you snap it on.

    The other thing you can check for the motor that is not spinning is to loosen the magnet. Sometimes this is pushed down to far and causing friction to prevent the motor shaft from spinning freely. If you hear a grinding noise like the motor is stalling, this is usually an indicator this is what is happening. You can use your fingernail or tool to loosen it. If the magnet comes off, you can easily put it back on. Try to see if that fixes your motor issue.

    I will send you a direct message to follow up on next steps.
